-.SH DESCRIPTION
-\&\fB do_dssp\fR
-\&reads a trajectory file and computes the secondary structure for
-\&each time frame
-\&calling the dssp program. If you do not have the dssp program,
-\&get it from http://swift.cmbi.ru.nl/gv/dssp. \fB do_dssp\fR assumes
-\&that the dssp executable is located in
-\&\fB /usr/local/bin/dssp\fR. If this is not the case, then you should
-\&set an environment variable \fB DSSP\fR pointing to the dssp
-\&executable, e.g.:
-
-
-\&\fB setenv DSSP /opt/dssp/bin/dssp\fR
-
-
-\&The structure assignment for each residue and time is written to an
-\&\fB .xpm\fR matrix file. This file can be visualized with for instance
-\&\fB xv\fR and can be converted to postscript with \fB xpm2ps\fR.
-\&Individual chains are separated by light grey lines in the \fB .xpm\fR and
-\&postscript files.
-\&The number of residues with each secondary structure type and the
-\&total secondary structure (\fB \-sss\fR) count as a function of
-\&time are also written to file (\fB \-sc\fR).
-
-
-\&Solvent accessible surface (SAS) per residue can be calculated, both in
-\&absolute values (A2) and in fractions of the maximal accessible
-\&surface of a residue. The maximal accessible surface is defined as
-\&the accessible surface of a residue in a chain of glycines.
-\&\fB Note\fR that the program \fB g_sas\fR can also compute SAS
-\&and that is more efficient.
-
-
-\&Finally, this program can dump the secondary structure in a special file
-\&\fB ssdump.dat\fR for usage in the program \fB g_chi\fR. Together
-\&these two programs can be used to analyze dihedral properties as a
-\&function of secondary structure type.

-.SH DESCRIPTION
-\&\fB editconf\fR converts generic structure format to \fB .gro\fR, \fB .g96\fR
-\&or \fB .pdb\fR.
-\&
-
-
-\&The box can be modified with options \fB \-box\fR, \fB \-d\fR and
-\&\fB \-angles\fR. Both \fB \-box\fR and \fB \-d\fR
-\&will center the system in the box, unless \fB \-noc\fR is used.
-\&
-
-
-\&Option \fB \-bt\fR determines the box type: \fB triclinic\fR is a
-\&triclinic box, \fB cubic\fR is a rectangular box with all sides equal
-\&\fB dodecahedron\fR represents a rhombic dodecahedron and
-\&\fB octahedron\fR is a truncated octahedron.
-\&The last two are special cases of a triclinic box.
-\&The length of the three box vectors of the truncated octahedron is the
-\&shortest distance between two opposite hexagons.
-\&Relative to a cubic box with some periodic image distance, the volume of a
-\&dodecahedron with this same periodic distance is 0.71 times that of the cube,
-\&and that of a truncated octahedron is 0.77 times.
-\&
-
-
-\&Option \fB \-box\fR requires only
-\&one value for a cubic, rhombic dodecahedral, or truncated octahedral box.
-\&
-
-
-\&With \fB \-d\fR and a \fB triclinic\fR box the size of the system in the \fI x\fR\-, \fI y\fR\-,
-\&and \fI z\fR\-directions is used. With \fB \-d\fR and \fB cubic\fR,
-\&\fB dodecahedron\fR or \fB octahedron\fR boxes, the dimensions are set
-\&to the diameter of the system (largest distance between atoms) plus twice
-\&the specified distance.
-\&
-
-
-\&Option \fB \-angles\fR is only meaningful with option \fB \-box\fR and
-\&a triclinic box and cannot be used with option \fB \-d\fR.
-\&
-
-
-\&When \fB \-n\fR or \fB \-ndef\fR is set, a group
-\&can be selected for calculating the size and the geometric center,
-\&otherwise the whole system is used.
-\&
-
-
-\&\fB \-rotate\fR rotates the coordinates and velocities.
-\&
-
-
-\&\fB \-princ\fR aligns the principal axes of the system along the
-\&coordinate axes, with the longest axis aligned with the \fI x\fR\-axis.
-\&This may allow you to decrease the box volume,
-\&but beware that molecules can rotate significantly in a nanosecond.
-\&
-
-
-\&Scaling is applied before any of the other operations are
-\&performed. Boxes and coordinates can be scaled to give a certain density (option
-\&\fB \-density\fR). Note that this may be inaccurate in case a \fB .gro\fR
-\&file is given as input. A special feature of the scaling option is that when the
-\&factor \-1 is given in one dimension, one obtains a mirror image,
-\&mirrored in one of the planes. When one uses \-1 in three dimensions,
-\&a point\-mirror image is obtained.
-
-
-\&Groups are selected after all operations have been applied.
-
-
-\&Periodicity can be removed in a crude manner.
-\&It is important that the box vectors at the bottom of your input file
-\&are correct when the periodicity is to be removed.
-\&
-
-
-\&When writing \fB .pdb\fR files, B\-factors can be
-\&added with the \fB \-bf\fR option. B\-factors are read
-\&from a file with with following format: first line states number of
-\&entries in the file, next lines state an index
-\&followed by a B\-factor. The B\-factors will be attached per residue
-\&unless an index is larger than the number of residues or unless the
-\&\fB \-atom\fR option is set. Obviously, any type of numeric data can
-\&be added instead of B\-factors. \fB \-legend\fR will produce
-\&a row of CA atoms with B\-factors ranging from the minimum to the
-\&maximum value found, effectively making a legend for viewing.
-\&
-
-
-\&With the option \fB \-mead\fR a special \fB .pdb\fR (\fB .pqr\fR)
-\&file for the MEAD electrostatics
-\&program (Poisson\-Boltzmann solver) can be made. A further prerequisite
-\&is that the input file is a run input file.
-\&The B\-factor field is then filled with the Van der Waals radius
-\&of the atoms while the occupancy field will hold the charge.
-\&
-
-
-\&The option \fB \-grasp\fR is similar, but it puts the charges in the B\-factor
-\&and the radius in the occupancy.
-\&
-
-
-\&Option \fB \-align\fR allows alignment
-\&of the principal axis of a specified group against the given vector,
-\&with an optional center of rotation specified by \fB \-aligncenter\fR.
-\&
-
-
-\&Finally, with option \fB \-label\fR, \fB editconf\fR can add a chain identifier
-\&to a \fB .pdb\fR file, which can be useful for analysis with e.g. Rasmol.
-\&
-
-
-\&To convert a truncated octrahedron file produced by a package which uses
-\&a cubic box with the corners cut off (such as GROMOS), use:
-
-\&\fB editconf \-f in \-rotate 0 45 35.264 \-bt o \-box veclen \-o out\fR
-
-\&where \fB veclen\fR is the size of the cubic box times sqrt(3)/2.

-.SH DESCRIPTION
-\&\fB g_anaeig\fR analyzes eigenvectors. The eigenvectors can be of a
-\&covariance matrix (\fB g_covar\fR) or of a Normal Modes analysis
-\&(\fB g_nmeig\fR).
-
-
-\&When a trajectory is projected on eigenvectors, all structures are
-\&fitted to the structure in the eigenvector file, if present, otherwise
-\&to the structure in the structure file. When no run input file is
-\&supplied, periodicity will not be taken into account. Most analyses
-\&are performed on eigenvectors \fB \-first\fR to \fB \-last\fR, but when
-\&\fB \-first\fR is set to \-1 you will be prompted for a selection.
-
-
-\&\fB \-comp\fR: plot the vector components per atom of eigenvectors
-\&\fB \-first\fR to \fB \-last\fR.
-
-
-\&\fB \-rmsf\fR: plot the RMS fluctuation per atom of eigenvectors
-\&\fB \-first\fR to \fB \-last\fR (requires \fB \-eig\fR).
-
-
-\&\fB \-proj\fR: calculate projections of a trajectory on eigenvectors
-\&\fB \-first\fR to \fB \-last\fR.
-\&The projections of a trajectory on the eigenvectors of its
-\&covariance matrix are called principal components (pc's).
-\&It is often useful to check the cosine content of the pc's,
-\&since the pc's of random diffusion are cosines with the number
-\&of periods equal to half the pc index.
-\&The cosine content of the pc's can be calculated with the program
-\&\fB g_analyze\fR.
-
-
-\&\fB \-2d\fR: calculate a 2d projection of a trajectory on eigenvectors
-\&\fB \-first\fR and \fB \-last\fR.
-
-
-\&\fB \-3d\fR: calculate a 3d projection of a trajectory on the first
-\&three selected eigenvectors.
-
-
-\&\fB \-filt\fR: filter the trajectory to show only the motion along
-\&eigenvectors \fB \-first\fR to \fB \-last\fR.
-
-
-\&\fB \-extr\fR: calculate the two extreme projections along a trajectory
-\&on the average structure and interpolate \fB \-nframes\fR frames
-\&between them, or set your own extremes with \fB \-max\fR. The
-\&eigenvector \fB \-first\fR will be written unless \fB \-first\fR and
-\&\fB \-last\fR have been set explicitly, in which case all eigenvectors
-\&will be written to separate files. Chain identifiers will be added
-\&when writing a \fB .pdb\fR file with two or three structures (you
-\&can use \fB rasmol \-nmrpdb\fR to view such a \fB .pdb\fR file).
-
-
-\& Overlap calculations between covariance analysis:
-
-\& \fB Note:\fR the analysis should use the same fitting structure
-
-
-\&\fB \-over\fR: calculate the subspace overlap of the eigenvectors in
-\&file \fB \-v2\fR with eigenvectors \fB \-first\fR to \fB \-last\fR
-\&in file \fB \-v\fR.
-
-
-\&\fB \-inpr\fR: calculate a matrix of inner\-products between
-\&eigenvectors in files \fB \-v\fR and \fB \-v2\fR. All eigenvectors
-\&of both files will be used unless \fB \-first\fR and \fB \-last\fR
-\&have been set explicitly.
-
-
-\&When \fB \-v\fR, \fB \-eig\fR, \fB \-v2\fR and \fB \-eig2\fR are given,
-\&a single number for the overlap between the covariance matrices is
-\&generated. The formulas are:
-
-\& difference = sqrt(tr((sqrt(M1) \- sqrt(M2))2))
-
-\&normalized overlap = 1 \- difference/sqrt(tr(M1) + tr(M2))
-
-\& shape overlap = 1 \- sqrt(tr((sqrt(M1/tr(M1)) \- sqrt(M2/tr(M2)))2))
-
-\&where M1 and M2 are the two covariance matrices and tr is the trace
-\&of a matrix. The numbers are proportional to the overlap of the square
-\&root of the fluctuations. The normalized overlap is the most useful
-\&number, it is 1 for identical matrices and 0 when the sampled
-\&subspaces are orthogonal.
-
-
-\&When the \fB \-entropy\fR flag is given an entropy estimate will be
-\&computed based on the Quasiharmonic approach and based on
-\&Schlitter's formula.

-.SH DESCRIPTION
-\&\fB g_analyze\fR reads an ASCII file and analyzes data sets.
-\&A line in the input file may start with a time
-\&(see option \fB \-time\fR) and any number of \fI y\fR\-values may follow.
-\&Multiple sets can also be
-\&read when they are separated by & (option \fB \-n\fR);
-\&in this case only one \fI y\fR\-value is read from each line.
-\&All lines starting with and @ are skipped.
-\&All analyses can also be done for the derivative of a set
-\&(option \fB \-d\fR).
-
-
-\&All options, except for \fB \-av\fR and \fB \-power\fR, assume that the
-\&points are equidistant in time.
-
-
-\&\fB g_analyze\fR always shows the average and standard deviation of each
-\&set, as well as the relative deviation of the third
-\&and fourth cumulant from those of a Gaussian distribution with the same
-\&standard deviation.
-
-
-\&Option \fB \-ac\fR produces the autocorrelation function(s).
-
-
-\&Option \fB \-cc\fR plots the resemblance of set i with a cosine of
-\&i/2 periods. The formula is:
-2 (int0\-T y(t) cos(i pi t) dt)2 / int0\-T y(t) y(t) dt
-
-\&This is useful for principal components obtained from covariance
-\&analysis, since the principal components of random diffusion are
-\&pure cosines.
-
-
-\&Option \fB \-msd\fR produces the mean square displacement(s).
-
-
-\&Option \fB \-dist\fR produces distribution plot(s).
-
-
-\&Option \fB \-av\fR produces the average over the sets.
-\&Error bars can be added with the option \fB \-errbar\fR.
-\&The errorbars can represent the standard deviation, the error
-\&(assuming the points are independent) or the interval containing
-\&90% of the points, by discarding 5% of the points at the top and
-\&the bottom.
-
-
-\&Option \fB \-ee\fR produces error estimates using block averaging.
-\&A set is divided in a number of blocks and averages are calculated for
-\&each block. The error for the total average is calculated from
-\&the variance between averages of the m blocks B_i as follows:
-\&error2 = Sum (B_i \- B)2 / (m*(m\-1)).
-\&These errors are plotted as a function of the block size.
-\&Also an analytical block average curve is plotted, assuming
-\&that the autocorrelation is a sum of two exponentials.
-\&The analytical curve for the block average is:
-
-\&f(t) = sigma\fB *\fRsqrt(2/T ( alpha (tau1 ((exp(\-t/tau1) \- 1) tau1/t + 1)) +
-
-\& (1\-alpha) (tau2 ((exp(\-t/tau2) \- 1) tau2/t + 1)))),
-where T is the total time.
-\&alpha, tau1 and tau2 are obtained by fitting f2(t) to error2.
-\&When the actual block average is very close to the analytical curve,
-\&the error is sigma\fB *\fRsqrt(2/T (a tau1 + (1\-a) tau2)).
-\&The complete derivation is given in
-\&B. Hess, J. Chem. Phys. 116:209\-217, 2002.
-
-
-\&Option \fB \-bal\fR finds and subtracts the ultrafast "ballistic"
-\&component from a hydrogen bond autocorrelation function by the fitting
-\&of a sum of exponentials, as described in e.g.
-\&O. Markovitch, J. Chem. Phys. 129:084505, 2008. The fastest term
-\&is the one with the most negative coefficient in the exponential,
-\&or with \fB \-d\fR, the one with most negative time derivative at time 0.
-\&\fB \-nbalexp\fR sets the number of exponentials to fit.
-
-
-\&Option \fB \-gem\fR fits bimolecular rate constants ka and kb
-\&(and optionally kD) to the hydrogen bond autocorrelation function
-\&according to the reversible geminate recombination model. Removal of
-\&the ballistic component first is strongly adviced. The model is presented in
-\&O. Markovitch, J. Chem. Phys. 129:084505, 2008.
-
-
-\&Option \fB \-filter\fR prints the RMS high\-frequency fluctuation
-\&of each set and over all sets with respect to a filtered average.
-\&The filter is proportional to cos(pi t/len) where t goes from \-len/2
-\&to len/2. len is supplied with the option \fB \-filter\fR.
-\&This filter reduces oscillations with period len/2 and len by a factor
-\&of 0.79 and 0.33 respectively.
-
-
-\&Option \fB \-g\fR fits the data to the function given with option
-\&\fB \-fitfn\fR.
-
-
-\&Option \fB \-power\fR fits the data to b ta, which is accomplished
-\&by fitting to a t + b on log\-log scale. All points after the first
-\&zero or with a negative value are ignored.
-
-Option \fB \-luzar\fR performs a Luzar & Chandler kinetics analysis
-\&on output from \fB g_hbond\fR. The input file can be taken directly
-\&from \fB g_hbond \-ac\fR, and then the same result should be produced.

-.SH DESCRIPTION
-\&\fB g_angle\fR computes the angle distribution for a number of angles
-\&or dihedrals. This way you can check whether your simulation
-\&is correct. With option \fB \-ov\fR you can plot the average angle of
-\&a group of angles as a function of time. With the \fB \-all\fR option
-\&the first graph is the average, the rest are the individual angles.
-
-
-\&With the \fB \-of\fR option, \fB g_angle\fR also calculates the fraction of trans
-\&dihedrals (only for dihedrals) as function of time, but this is
-\&probably only fun for a selected few.
-
-
-\&With option \fB \-oc\fR a dihedral correlation function is calculated.
-
-
-\&It should be noted that the index file should contain
-\&atom\-triples for angles or atom\-quadruplets for dihedrals.
-\&If this is not the case, the program will crash.
-
-
-\&With option \fB \-or\fR a trajectory file is dumped containing cos and
-\&sin of selected dihedral angles which subsequently can be used as
-\&input for a PCA analysis using \fB g_covar\fR.

-.SH DESCRIPTION
-\&\fB g_bar\fR calculates free energy difference estimates through
-\&Bennett's acceptance ratio method (BAR). It also automatically
-\&adds series of individual free energies obtained with BAR into
-\&a combined free energy estimate.
-
-
-\&Every individual BAR free energy difference relies on two
-\&simulations at different states: say state A and state B, as
-\&controlled by a parameter, lambda (see the \fB .mdp\fR parameter
-\&\fB init_lambda\fR). The BAR method calculates a ratio of weighted
-\&average of the Hamiltonian difference of state B given state A and
-\&vice versa. If the Hamiltonian does not depend linearly on lambda
-\&(in which case we can extrapolate the derivative of the Hamiltonian
-\&with respect to lambda, as is the default when \fB free_energy\fR is on),
-\&the energy differences to the other state need to be calculated
-\&explicitly during the simulation. This can be controlled with
-\&the \fB .mdp\fR option \fB foreign_lambda\fR.
-
-
-\&Input option \fB \-f\fR expects multiple \fB dhdl.xvg\fR files.
-\&Two types of input files are supported:
-
-\&\fB *\fR Files with only one \fI y\fR\-value, for such files it is assumed
-\& that the \fI y\fR\-value is dH/dlambda and that the Hamiltonian depends
-\& linearly on lambda. The lambda value of the simulation is inferred
-\& from the subtitle (if present), otherwise from a number in the
-\& subdirectory in the file name.
-\&
-
-\&\fB *\fR Files with more than one \fI y\fR\-value. The files should have columns
-\& with dH/dlambda and Deltalambda. The lambda values are inferred
-\& from the legends: lambda of the simulation from the legend of dH/dlambda
-\& and the foreign lambda values from the legends of Delta H.
-
-
-\&The lambda of the simulation is parsed from \fB dhdl.xvg\fR file's legend
-\&containing the string 'dH', the foreign lambda values from the legend
-\&containing the capitalized letters 'D' and 'H'. The temperature
-\&is parsed from the legend line containing 'T ='.
-
-
-\&The input option \fB \-g\fR expects multiple \fB .edr\fR files.
-\&These can contain either lists of energy differences (see the
-\&\fB .mdp\fR option \fB separate_dhdl_file\fR), or a series of histograms
-\&(see the \fB .mdp\fR options \fB dh_hist_size\fR and \fB dh_hist_spacing\fR).
-\&The temperature and lambda values are automatically deduced from
-\&the \fB ener.edr\fR file.
-
-The free energy estimates are determined using BAR with bisection,
-\&with the precision of the output set with \fB \-prec\fR.
-\&An error estimate taking into account time correlations
-\&is made by splitting the data into blocks and determining
-\&the free energy differences over those blocks and assuming
-\&the blocks are independent.
-\&The final error estimate is determined from the average variance
-\&over 5 blocks. A range of block numbers for error estimation can
-\&be provided with the options \fB \-nbmin\fR and \fB \-nbmax\fR.
-
-
-\&\fB g_bar\fR tries to aggregate samples with the same 'native' and 'foreign'
-\&lambda values, but always assumes independent samples. \fB Note\fR that
-\&when aggregating energy differences/derivatives with different
-\&sampling intervals, this is almost certainly not correct. Usually
-\&subsequent energies are correlated and different time intervals mean
-\&different degrees of correlation between samples.
-
-
-\&The results are split in two parts: the last part contains the final
-\&results in kJ/mol, together with the error estimate for each part
-\&and the total. The first part contains detailed free energy
-\&difference estimates and phase space overlap measures in units of
-\&kT (together with their computed error estimate). The printed
-\&values are:
-
-\&\fB *\fR lam_A: the lambda values for point A.
-
-\&\fB *\fR lam_B: the lambda values for point B.
-
-\&\fB *\fR DG: the free energy estimate.
-
-\&\fB *\fR s_A: an estimate of the relative entropy of B in A.
-
-\&\fB *\fR s_A: an estimate of the relative entropy of A in B.
-
-\&\fB *\fR stdev: an estimate expected per\-sample standard deviation.
-
-
-\&The relative entropy of both states in each other's ensemble can be
-\&interpreted as a measure of phase space overlap:
-\&the relative entropy s_A of the work samples of lambda_B in the
-\&ensemble of lambda_A (and vice versa for s_B), is a
-\&measure of the 'distance' between Boltzmann distributions of
-\&the two states, that goes to zero for identical distributions. See
-\&Wu & Kofke, J. Chem. Phys. 123 084109 (2005) for more information.
-\&
-
-
-\&The estimate of the expected per\-sample standard deviation, as given
-\&in Bennett's original BAR paper: Bennett, J. Comp. Phys. 22, p 245 (1976).
-\&Eq. 10 therein gives an estimate of the quality of sampling (not directly
-\&of the actual statistical error, because it assumes independent samples).
-
-
-\&To get a visual estimate of the phase space overlap, use the
-\&\fB \-oh\fR option to write series of histograms, together with the
-\&\fB \-nbin\fR option.

-.SH DESCRIPTION
-\&\fB g_chi\fR computes phi, psi, omega, and chi dihedrals for all your
-\&amino acid backbone and sidechains.
-\&It can compute dihedral angle as a function of time, and as
-\&histogram distributions.
-\&The distributions \fB (histo\-(dihedral)(RESIDUE).xvg\fR) are cumulative over all residues of each type.
-
-
-\&If option \fB \-corr\fR is given, the program will
-\&calculate dihedral autocorrelation functions. The function used
-\&is C(t) = cos(chi(tau)) cos(chi(tau+t)) . The use of cosines
-\&rather than angles themselves, resolves the problem of periodicity.
-\&(Van der Spoel & Berendsen (1997), Biophys. J. 72, 2032\-2041).
-\&Separate files for each dihedral of each residue
-\&\fB (corr(dihedral)(RESIDUE)(nresnr).xvg\fR) are output, as well as a
-\&file containing the information for all residues (argument of \fB \-corr\fR).
-
-
-\&With option \fB \-all\fR, the angles themselves as a function of time for
-\&each residue are printed to separate files \fB (dihedral)(RESIDUE)(nresnr).xvg\fR.
-\&These can be in radians or degrees.
-
-
-\&A log file (argument \fB \-g\fR) is also written. This contains
-
-\&(a) information about the number of residues of each type.
-
-\&(b) The NMR 3J coupling constants from the Karplus equation.
-
-\&(c) a table for each residue of the number of transitions between
-\&rotamers per nanosecond, and the order parameter S2 of each dihedral.
-
-\&(d) a table for each residue of the rotamer occupancy.
-
-
-\&All rotamers are taken as 3\-fold, except for omega and chi dihedrals
-\&to planar groups (i.e. chi2 of aromatics, Asp and Asn; chi3 of Glu
-\&and Gln; and chi4 of Arg), which are 2\-fold. "rotamer 0" means
-\&that the dihedral was not in the core region of each rotamer.
-\&The width of the core region can be set with \fB \-core_rotamer\fR
-
-
-\&The S2 order parameters are also output to an \fB .xvg\fR file
-\&(argument \fB \-o\fR ) and optionally as a \fB .pdb\fR file with
-\&the S2 values as B\-factor (argument \fB \-p\fR).
-\&The total number of rotamer transitions per timestep
-\&(argument \fB \-ot\fR), the number of transitions per rotamer
-\&(argument \fB \-rt\fR), and the 3J couplings (argument \fB \-jc\fR),
-\&can also be written to \fB .xvg\fR files.
-
-
-\&If \fB \-chi_prod\fR is set (and \fB \-maxchi\fR 0), cumulative rotamers, e.g.
-\&1+9(chi1\-1)+3(chi2\-1)+(chi3\-1) (if the residue has three 3\-fold
-\&dihedrals and \fB \-maxchi\fR = 3)
-\&are calculated. As before, if any dihedral is not in the core region,
-\&the rotamer is taken to be 0. The occupancies of these cumulative
-\&rotamers (starting with rotamer 0) are written to the file
-\&that is the argument of \fB \-cp\fR, and if the \fB \-all\fR flag
-\&is given, the rotamers as functions of time
-\&are written to \fB chiproduct(RESIDUE)(nresnr).xvg\fR
-\&and their occupancies to \fB histo\-chiproduct(RESIDUE)(nresnr).xvg\fR.
-
-
-\&The option \fB \-r\fR generates a contour plot of the average omega angle
-\&as a function of the phi and psi angles, that is, in a Ramachandran plot
-\&the average omega angle is plotted using color coding.

-.SH KNOWN PROBLEMS
-\- Produces MANY output files (up to about 4 times the number of residues in the protein, twice that if autocorrelation functions are calculated). Typically several hundred files are output.
-
-\- phi and psi dihedrals are calculated in a non\-standard way, using H\-N\-CA\-C for phi instead of C(\-)\-N\-CA\-C, and N\-CA\-C\-O for psi instead of N\-CA\-C\-N(+). This causes (usually small) discrepancies with the output of other tools like \fB g_rama\fR.
-
-\- \fB \-r0\fR option does not work properly
-
-\- Rotamers with multiplicity 2 are printed in \fB chi.log\fR as if they had multiplicity 3, with the 3rd (g(+)) always having probability 0

-.SH DESCRIPTION
-\&\fB g_cluster\fR can cluster structures using several different methods.
-\&Distances between structures can be determined from a trajectory
-\&or read from an \fB .xpm\fR matrix file with the \fB \-dm\fR option.
-\&RMS deviation after fitting or RMS deviation of atom\-pair distances
-\&can be used to define the distance between structures.
-
-
-\&single linkage: add a structure to a cluster when its distance to any
-\&element of the cluster is less than \fB cutoff\fR.
-
-
-\&Jarvis Patrick: add a structure to a cluster when this structure
-\&and a structure in the cluster have each other as neighbors and
-\&they have a least \fB P\fR neighbors in common. The neighbors
-\&of a structure are the M closest structures or all structures within
-\&\fB cutoff\fR.
-
-
-\&Monte Carlo: reorder the RMSD matrix using Monte Carlo.
-
-
-\&diagonalization: diagonalize the RMSD matrix.
-
-
-\&gromos: use algorithm as described in Daura \fI et al.\fR
-\&(\fI Angew. Chem. Int. Ed.\fR \fB 1999\fR, \fI 38\fR, pp 236\-240).
-\&Count number of neighbors using cut\-off, take structure with
-\&largest number of neighbors with all its neighbors as cluster
-\&and eliminate it from the pool of clusters. Repeat for remaining
-\&structures in pool.
-
-
-\&When the clustering algorithm assigns each structure to exactly one
-\&cluster (single linkage, Jarvis Patrick and gromos) and a trajectory
-\&file is supplied, the structure with
-\&the smallest average distance to the others or the average structure
-\&or all structures for each cluster will be written to a trajectory
-\&file. When writing all structures, separate numbered files are made
-\&for each cluster.
-
-
-\&Two output files are always written:
-
-\&\fB \-o\fR writes the RMSD values in the upper left half of the matrix
-\&and a graphical depiction of the clusters in the lower right half
-\&When \fB \-minstruct\fR = 1 the graphical depiction is black
-\&when two structures are in the same cluster.
-\&When \fB \-minstruct\fR 1 different colors will be used for each
-\&cluster.
-
-\&\fB \-g\fR writes information on the options used and a detailed list
-\&of all clusters and their members.
-
-
-\&Additionally, a number of optional output files can be written:
-
-\&\fB \-dist\fR writes the RMSD distribution.
-
-\&\fB \-ev\fR writes the eigenvectors of the RMSD matrix
-\&diagonalization.
-
-\&\fB \-sz\fR writes the cluster sizes.
-
-\&\fB \-tr\fR writes a matrix of the number transitions between
-\&cluster pairs.
-
-\&\fB \-ntr\fR writes the total number of transitions to or from
-\&each cluster.
-
-\&\fB \-clid\fR writes the cluster number as a function of time.
-
-\&\fB \-cl\fR writes average (with option \fB \-av\fR) or central
-\&structure of each cluster or writes numbered files with cluster members
-\&for a selected set of clusters (with option \fB \-wcl\fR, depends on
-\&\fB \-nst\fR and \fB \-rmsmin\fR).

-.SH DESCRIPTION
-\&This program computes the size distributions of molecular/atomic clusters in

-\&The total number of clusters is written to an \fB .xvg\fR file.
-
-
-\&When the \fB \-mol\fR option is given clusters will be made out of

-\&In this case an index file would still contain atom numbers
-\&or your calculation will die with a SEGV.
-
-
-\&When velocities are present in your trajectory, the temperature of
-\&the largest cluster will be printed in a separate \fB .xvg\fR file assuming
-\&that the particles are free to move. If you are using constraints,
-\&please correct the temperature. For instance water simulated with SHAKE
-\&or SETTLE will yield a temperature that is 1.5 times too low. You can
-\&compensate for this with the \fB \-ndf\fR option. Remember to take the removal
-\&of center of mass motion into account.
-
-
-\&The \fB \-mc\fR option will produce an index file containing the
-\&atom numbers of the largest cluster.

-\&\fB g_confrms\fR computes the root mean square deviation (RMSD) of two
-\&structures after least\-squares fitting the second structure on the first one.
-\&The two structures do NOT need to have the same number of atoms,
-\&only the two index groups used for the fit need to be identical.
-\&With \fB \-name\fR only matching atom names from the selected groups
-\&will be used for the fit and RMSD calculation. This can be useful
-\&when comparing mutants of a protein.
-\&
-
-
-\&The superimposed structures are written to file. In a \fB .pdb\fR file
-\&the two structures will be written as separate models
-\&(use \fB rasmol \-nmrpdb\fR). Also in a \fB .pdb\fR file, B\-factors
-\&calculated from the atomic MSD values can be written with \fB \-bfac\fR.

-.SH DESCRIPTION
-\&\fB g_covar\fR calculates and diagonalizes the (mass\-weighted)
-\&covariance matrix.
-\&All structures are fitted to the structure in the structure file.
-\&When this is not a run input file periodicity will not be taken into
-\&account. When the fit and analysis groups are identical and the analysis
-\&is non mass\-weighted, the fit will also be non mass\-weighted.
-\&
-
-
-\&The eigenvectors are written to a trajectory file (\fB \-v\fR).
-\&When the same atoms are used for the fit and the covariance analysis,
-\&the reference structure for the fit is written first with t=\-1.
-\&The average (or reference when \fB \-ref\fR is used) structure is
-\&written with t=0, the eigenvectors
-\&are written as frames with the eigenvector number as timestamp.
-\&
-
-
-\&The eigenvectors can be analyzed with \fB g_anaeig\fR.
-\&
-
-
-\&Option \fB \-ascii\fR writes the whole covariance matrix to
-\&an ASCII file. The order of the elements is: x1x1, x1y1, x1z1, x1x2, ...
-\&
-
-
-\&Option \fB \-xpm\fR writes the whole covariance matrix to an \fB .xpm\fR file.
-\&
-
-
-\&Option \fB \-xpma\fR writes the atomic covariance matrix to an \fB .xpm\fR file,
-\&i.e. for each atom pair the sum of the xx, yy and zz covariances is
-\&written.
-\&
-
-
-\&Note that the diagonalization of a matrix requires memory and time
-\&that will increase at least as fast as than the square of the number
-\&of atoms involved. It is easy to run out of memory, in which
-\&case this tool will probably exit with a 'Segmentation fault'. You
-\&should consider carefully whether a reduced set of atoms will meet
-\&your needs for lower costs.

-.SH DESCRIPTION
-\&\fB g_current\fR is a tool for calculating the current autocorrelation function, the correlation
-\&of the rotational and translational dipole moment of the system, and the resulting static
-\&dielectric constant. To obtain a reasonable result, the index group has to be neutral.
-\&Furthermore, the routine is capable of extracting the static conductivity from the current
-\&autocorrelation function, if velocities are given. Additionally, an Einstein\-Helfand fit
-\&can be used to obtain the static conductivity.
-
-
-\&The flag \fB \-caf\fR is for the output of the current autocorrelation function and \fB \-mc\fR writes the
-\&correlation of the rotational and translational part of the dipole moment in the corresponding
-\&file. However, this option is only available for trajectories containing velocities.
-\&Options \fB \-sh\fR and \fB \-tr\fR are responsible for the averaging and integration of the
-\&autocorrelation functions. Since averaging proceeds by shifting the starting point
-\&through the trajectory, the shift can be modified with \fB \-sh\fR to enable the choice of uncorrelated
-\&starting points. Towards the end, statistical inaccuracy grows and integrating the
-\&correlation function only yields reliable values until a certain point, depending on
-\&the number of frames. The option \fB \-tr\fR controls the region of the integral taken into account
-\&for calculating the static dielectric constant.
-\&
-
-
-\&Option \fB \-temp\fR sets the temperature required for the computation of the static dielectric constant.
-\&
-
-
-\&Option \fB \-eps\fR controls the dielectric constant of the surrounding medium for simulations using
-\&a Reaction Field or dipole corrections of the Ewald summation (eps=0 corresponds to
-\&tin\-foil boundary conditions).
-\&
-
-
-\&\fB \-[no]nojump\fR unfolds the coordinates to allow free diffusion. This is required to get a continuous
-\&translational dipole moment, required for the Einstein\-Helfand fit. The results from the fit allow
-\&the determination of the dielectric constant for system of charged molecules. However, it is also possible to extract
-\&the dielectric constant from the fluctuations of the total dipole moment in folded coordinates. But this
-\&option has to be used with care, since only very short time spans fulfill the approximation that the density
-\&of the molecules is approximately constant and the averages are already converged. To be on the safe side,
-\&the dielectric constant should be calculated with the help of the Einstein\-Helfand method for
-\&the translational part of the dielectric constant.

-\&Optionally, output can be in text form to a \fB .dat\fR file with \fB \-od\fR, instead of the usual \fB .xpm\fR file with \fB \-o\fR.
-\&
-
-
-\&The default analysis is a 2\-D number\-density map for a selected
-\&group of atoms in the x\-y plane.
-\&The averaging direction can be changed with the option \fB \-aver\fR.
-\&When \fB \-xmin\fR and/or \fB \-xmax\fR are set only atoms that are
-\&within the limit(s) in the averaging direction are taken into account.
-\&The grid spacing is set with the option \fB \-bin\fR.
-\&When \fB \-n1\fR or \fB \-n2\fR is non\-zero, the grid
-\&size is set by this option.
-\&Box size fluctuations are properly taken into account.
-\&
-
-
-\&When options \fB \-amax\fR and \fB \-rmax\fR are set, an axial\-radial
-\&number\-density map is made. Three groups should be supplied, the centers
-\&of mass of the first two groups define the axis, the third defines the
-\&analysis group. The axial direction goes from \-amax to +amax, where
-\&the center is defined as the midpoint between the centers of mass and
-\&the positive direction goes from the first to the second center of mass.
-\&The radial direction goes from 0 to rmax or from \-rmax to +rmax
-\&when the \fB \-mirror\fR option has been set.
-\&
-
-
-\&The normalization of the output is set with the \fB \-unit\fR option.
-\&The default produces a true number density. Unit \fB nm\-2\fR leaves out
-\&the normalization for the averaging or the angular direction.
-\&Option \fB count\fR produces the count for each grid cell.
-\&When you do not want the scale in the output to go
-\&from zero to the maximum density, you can set the maximum
-\&with the option \fB \-dmax\fR.

-.SH DESCRIPTION
-\&\fB g_dielectric\fR calculates frequency dependent dielectric constants
-\&from the autocorrelation function of the total dipole moment in
-\&your simulation. This ACF can be generated by \fB g_dipoles\fR.
-\&For an estimate of the error you can run g_statistics on the
-\&ACF, and use the output thus generated for this program.
-\&The functional forms of the available functions are:
-
-
-\&One parameter: y = Exp[\-a1 x],
-
-\&Two parameters: y = a2 Exp[\-a1 x],
-
-\&Three parameters: y = a2 Exp[\-a1 x] + (1 \- a2) Exp[\-a3 x].
-
-\&Start values for the fit procedure can be given on the command line.
-\&It is also possible to fix parameters at their start value, use \fB \-fix\fR
-\&with the number of the parameter you want to fix.
-\&
-
-
-\&Three output files are generated, the first contains the ACF,
-\&an exponential fit to it with 1, 2 or 3 parameters, and the
-\&numerical derivative of the combination data/fit.
-\&The second file contains the real and imaginary parts of the
-\&frequency\-dependent dielectric constant, the last gives a plot
-\&known as the Cole\-Cole plot, in which the imaginary
-\&component is plotted as a function of the real component.
-\&For a pure exponential relaxation (Debye relaxation) the latter
-\&plot should be one half of a circle.

-.SH DESCRIPTION
-\&\fB g_dipoles\fR computes the total dipole plus fluctuations of a simulation
-\&system. From this you can compute e.g. the dielectric constant for
-\&low\-dielectric media.
-\&For molecules with a net charge, the net charge is subtracted at
-\¢er of mass of the molecule.
-
-
-\&The file \fB Mtot.xvg\fR contains the total dipole moment of a frame, the
-\&components as well as the norm of the vector.
-\&The file \fB aver.xvg\fR contains |Mu|2 and | Mu |2 during the
-\&simulation.
-\&The file \fB dipdist.xvg\fR contains the distribution of dipole moments during
-\&the simulation
-\&The value of \fB \-mumax\fR is used as the highest value in the distribution graph.
-
-
-\&Furthermore, the dipole autocorrelation function will be computed when
-\&option \fB \-corr\fR is used. The output file name is given with the \fB \-c\fR
-\&option.
-\&The correlation functions can be averaged over all molecules
-\&(\fB mol\fR), plotted per molecule separately (\fB molsep\fR)
-\&or it can be computed over the total dipole moment of the simulation box
-\&(\fB total\fR).
-
-
-\&Option \fB \-g\fR produces a plot of the distance dependent Kirkwood
-\&G\-factor, as well as the average cosine of the angle between the dipoles
-\&as a function of the distance. The plot also includes gOO and hOO
-\&according to Nymand & Linse, J. Chem. Phys. 112 (2000) pp 6386\-6395. In the same plot,
-\&we also include the energy per scale computed by taking the inner product of
-\&the dipoles divided by the distance to the third power.

-\&This will calculate the autocorrelation function of the molecular
-\&dipoles using a first order Legendre polynomial of the angle of the
-\&dipole vector and itself a time t later. For this calculation 1001
-\&frames will be used. Further, the dielectric constant will be calculated
-\&using an epsilonRF of infinity (default), temperature of 300 K (default) and
-\&an average dipole moment of the molecule of 2.273 (SPC). For the
-\&distribution function a maximum of 5.0 will be used.

-.SH DESCRIPTION
-\&\fB g_dyndom\fR reads a \fB .pdb\fR file output from DynDom
-\&(http://www.cmp.uea.ac.uk/dyndom/).
-\&It reads the coordinates, the coordinates of the rotation axis,
-\&and an index file containing the domains.
-\&Furthermore, it takes the first and last atom of the arrow file
-\&as command line arguments (head and tail) and
-\&finally it takes the translation vector (given in DynDom info file)
-\&and the angle of rotation (also as command line arguments). If the angle
-\&determined by DynDom is given, one should be able to recover the
-\&second structure used for generating the DynDom output.
-\&Because of limited numerical accuracy this should be verified by
-\&computing an all\-atom RMSD (using \fB g_confrms\fR) rather than by file
-\&comparison (using diff).
-
-
-\&The purpose of this program is to interpolate and extrapolate the
-\&rotation as found by DynDom. As a result unphysical structures with
-\&long or short bonds, or overlapping atoms may be produced. Visual
-\&inspection, and energy minimization may be necessary to
-\&validate the structure.

-.SH DESCRIPTION
-\&\fB g_enemat\fR extracts an energy matrix from the energy file (\fB \-f\fR).
-\&With \fB \-groups\fR a file must be supplied with on each
-\&line a group of atoms to be used. For these groups matrix of
-\&interaction energies will be extracted from the energy file
-\&by looking for energy groups with names corresponding to pairs
-\&of groups of atoms, e.g. if your \fB \-groups\fR file contains:
-
-\&\fB 2\fR
-
-\&\fB Protein\fR
-
-\&\fB SOL\fR
-
-\&then energy groups with names like 'Coul\-SR:Protein\-SOL' and
-\&'LJ:Protein\-SOL' are expected in the energy file (although
-\&\fB g_enemat\fR is most useful if many groups are analyzed
-\&simultaneously). Matrices for different energy types are written
-\&out separately, as controlled by the
-\&\fB \-[no]coul\fR, \fB \-[no]coulr\fR, \fB \-[no]coul14\fR,
-\&\fB \-[no]lj\fR, \fB \-[no]lj14\fR,
-\&\fB \-[no]bham\fR and \fB \-[no]free\fR options.
-\&Finally, the total interaction energy energy per group can be
-\&calculated (\fB \-etot\fR).
-
-
-\&An approximation of the free energy can be calculated using:
-\&E(free) = E0 + kT log( exp((E\-E0)/kT) ), where ''
-\&stands for time\-average. A file with reference free energies
-\&can be supplied to calculate the free energy difference
-\&with some reference state. Group names (e.g. residue names)
-\&in the reference file should correspond to the group names
-\&as used in the \fB \-groups\fR file, but a appended number
-\&(e.g. residue number) in the \fB \-groups\fR will be ignored
-\&in the comparison.

-.SH DESCRIPTION
-\&\fB g_energy\fR extracts energy components or distance restraint
-\&data from an energy file. The user is prompted to interactively
-\&select the desired energy terms.
-
-
-\&Average, RMSD, and drift are calculated with full precision from the
-\&simulation (see printed manual). Drift is calculated by performing
-\&a least\-squares fit of the data to a straight line. The reported total drift
-\&is the difference of the fit at the first and last point.
-\&An error estimate of the average is given based on a block averages
-\&over 5 blocks using the full\-precision averages. The error estimate
-\&can be performed over multiple block lengths with the options
-\&\fB \-nbmin\fR and \fB \-nbmax\fR.
-\&\fB Note\fR that in most cases the energy files contains averages over all
-\&MD steps, or over many more points than the number of frames in
-\&energy file. This makes the \fB g_energy\fR statistics output more accurate
-\&than the \fB .xvg\fR output. When exact averages are not present in the energy
-\&file, the statistics mentioned above are simply over the single, per\-frame
-\&energy values.
-
-
-\&The term fluctuation gives the RMSD around the least\-squares fit.
-
-
-\&When the \fB \-viol\fR option is set, the time averaged
-\&violations are plotted and the running time\-averaged and
-\&instantaneous sum of violations are recalculated. Additionally
-\&running time\-averaged and instantaneous distances between
-\&selected pairs can be plotted with the \fB \-pairs\fR option.
-
-
-\&Options \fB \-ora\fR, \fB \-ort\fR, \fB \-oda\fR, \fB \-odr\fR and
-\&\fB \-odt\fR are used for analyzing orientation restraint data.
-\&The first two options plot the orientation, the last three the
-\&deviations of the orientations from the experimental values.
-\&The options that end on an 'a' plot the average over time
-\&as a function of restraint. The options that end on a 't'
-\&prompt the user for restraint label numbers and plot the data
-\&as a function of time. Option \fB \-odr\fR plots the RMS
-\&deviation as a function of restraint.
-\&When the run used time or ensemble averaged orientation restraints,
-\&option \fB \-orinst\fR can be used to analyse the instantaneous,
-\¬ ensemble\-averaged orientations and deviations instead of
-\&the time and ensemble averages.
-
-
-\&Option \fB \-oten\fR plots the eigenvalues of the molecular order
-\&tensor for each orientation restraint experiment. With option
-\&\fB \-ovec\fR also the eigenvectors are plotted.
-
-
-\&Option \fB \-odh\fR extracts and plots the free energy data
-\&(Hamiltoian differences and/or the Hamiltonian derivative dhdl)
-\&from the \fB ener.edr\fR file.
-
-
-\&With \fB \-fee\fR an estimate is calculated for the free\-energy
-\&difference with an ideal gas state:
-
-\& Delta A = A(N,V,T) \- A_idgas(N,V,T) = kT ln e(Upot/kT)
-
-\& Delta G = G(N,p,T) \- G_idgas(N,p,T) = kT ln e(Upot/kT)
-
-\&where k is Boltzmann's constant, T is set by \fB \-fetemp\fR and
-\&the average is over the ensemble (or time in a trajectory).
-\&Note that this is in principle
-\&only correct when averaging over the whole (Boltzmann) ensemble
-\&and using the potential energy. This also allows for an entropy
-\&estimate using:
-
-\& Delta S(N,V,T) = S(N,V,T) \- S_idgas(N,V,T) = (Upot \- Delta A)/T
-
-\& Delta S(N,p,T) = S(N,p,T) \- S_idgas(N,p,T) = (Upot + pV \- Delta G)/T
-\&
-
-
-\&When a second energy file is specified (\fB \-f2\fR), a free energy
-\&difference is calculated dF = \-kT ln e \-(EB\-EA)/kT A ,
-\&where EA and EB are the energies from the first and second energy
-\&files, and the average is over the ensemble A. The running average
-\&of the free energy difference is printed to a file specified by \fB \-ravg\fR.
-\&\fB Note\fR that the energies must both be calculated from the same trajectory.

-.SH DESCRIPTION
-\&\fB g_filter\fR performs frequency filtering on a trajectory.
-\&The filter shape is cos(pi t/A) + 1 from \-A to +A, where A is given
-\&by the option \fB \-nf\fR times the time step in the input trajectory.
-\&This filter reduces fluctuations with period A by 85%, with period
-\&2*A by 50% and with period 3*A by 17% for low\-pass filtering.
-\&Both a low\-pass and high\-pass filtered trajectory can be written.
-
-
-\&Option \fB \-ol\fR writes a low\-pass filtered trajectory.
-\&A frame is written every \fB \-nf\fR input frames.
-\&This ratio of filter length and output interval ensures a good
-\&suppression of aliasing of high\-frequency motion, which is useful for
-\&making smooth movies. Also averages of properties which are linear
-\&in the coordinates are preserved, since all input frames are weighted
-\&equally in the output.
-\&When all frames are needed, use the \fB \-all\fR option.
-
-
-\&Option \fB \-oh\fR writes a high\-pass filtered trajectory.
-\&The high\-pass filtered coordinates are added to the coordinates
-\&from the structure file. When using high\-pass filtering use \fB \-fit\fR
-\&or make sure you use a trajectory that has been fitted on
-\&the coordinates in the structure file.

-.SH DESCRIPTION
-\&\fB g_hbond\fR computes and analyzes hydrogen bonds. Hydrogen bonds are
-\&determined based on cutoffs for the angle Acceptor \- Donor \- Hydrogen
-\&(zero is extended) and the distance Hydrogen \- Acceptor.
-\&OH and NH groups are regarded as donors, O is an acceptor always,
-\&N is an acceptor by default, but this can be switched using
-\&\fB \-nitacc\fR. Dummy hydrogen atoms are assumed to be connected
-\&to the first preceding non\-hydrogen atom.
-
-
-\&You need to specify two groups for analysis, which must be either
-\&identical or non\-overlapping. All hydrogen bonds between the two
-\&groups are analyzed.
-
-
-\&If you set \fB \-shell\fR, you will be asked for an additional index group
-\&which should contain exactly one atom. In this case, only hydrogen
-\&bonds between atoms within the shell distance from the one atom are
-\&considered.

-.SH DESCRIPTION
-\&\fB g_helix\fR computes all kinds of helix properties. First, the peptide
-\&is checked to find the longest helical part, as determined by
-\&hydrogen bonds and phi/psi angles.
-\&That bit is fitted
-\&to an ideal helix around the \fI z\fR\-axis and centered around the origin.
-\&Then the following properties are computed:
-
-
-\&\fB 1.\fR Helix radius (file \fB radius.xvg\fR). This is merely the
-\&RMS deviation in two dimensions for all Calpha atoms.
-\&it is calced as sqrt((SUM i(x2(i)+y2(i)))/N), where N is the number
-\&of backbone atoms. For an ideal helix the radius is 0.23 nm
-
-\&\fB 2.\fR Twist (file \fB twist.xvg\fR). The average helical angle per
-\&residue is calculated. For an alpha\-helix it is 100 degrees,
-\&for 3\-10 helices it will be smaller, and
-\&for 5\-helices it will be larger.
-
-\&\fB 3.\fR Rise per residue (file \fB rise.xvg\fR). The helical rise per
-\&residue is plotted as the difference in \fI z\fR\-coordinate between Calpha
-\&atoms. For an ideal helix, this is 0.15 nm
-
-\&\fB 4.\fR Total helix length (file \fB len\-ahx.xvg\fR). The total length
-\&of the
-\&helix in nm. This is simply the average rise (see above) times the
-\&number of helical residues (see below).
-
-\&\fB 5.\fR Number of helical residues (file \fB n\-ahx.xvg\fR). The title says
-\&it all.
-
-\&\fB 6.\fR Helix dipole, backbone only (file \fB dip\-ahx.xvg\fR).
-
-\&\fB 7.\fR RMS deviation from ideal helix, calculated for the Calpha
-\&atoms only (file \fB rms\-ahx.xvg\fR).
-
-\&\fB 8.\fR Average Calpha \- Calpha dihedral angle (file \fB phi\-ahx.xvg\fR).
-
-\&\fB 9.\fR Average phi and psi angles (file \fB phipsi.xvg\fR).
-
-\&\fB 10.\fR Ellipticity at 222 nm according to Hirst and Brooks.

-.SH DESCRIPTION
-\&\fB g_helixorient\fR calculates the coordinates and direction of the average
-\&axis inside an alpha helix, and the direction/vectors of both the
-\&Calpha and (optionally) a sidechain atom relative to the axis.
-
-
-\&As input, you need to specify an index group with Calpha atoms
-\&corresponding to an alpha\-helix of continuous residues. Sidechain
-\&directions require a second index group of the same size, containing
-\&the heavy atom in each residue that should represent the sidechain.
-
-
-\&\fB Note\fR that this program does not do any fitting of structures.
-
-
-\&We need four Calpha coordinates to define the local direction of the helix
-\&axis.
-
-
-\&The tilt/rotation is calculated from Euler rotations, where we define
-\&the helix axis as the local \fI x\fR\-axis, the residues/Calpha vector as \fI y\fR, and the
-\&\fI z\fR\-axis from their cross product. We use the Euler Y\-Z\-X rotation, meaning
-\&we first tilt the helix axis (1) around and (2) orthogonal to the residues
-\&vector, and finally apply the (3) rotation around it. For debugging or other
-\&purposes, we also write out the actual Euler rotation angles as \fB theta[1\-3].xvg\fR

-\&\fB g_membed\fR embeds a membrane protein into an equilibrated lipid bilayer at the position
-\&and orientation specified by the user.
-
-
-\&SHORT MANUAL
-\-\-\-\-\-\-\-\-\-\-\-\-
-
-\&The user should merge the structure files of the protein and membrane (+solvent), creating a
-\&single structure file with the protein overlapping the membrane at the desired position and
-\&orientation. The box size is taken from the membrane structure file. The corresponding topology
-\&files should also be merged. Consecutively, create a \fB .tpr\fR file (input for \fB g_membed\fR) from these files,with the following options included in the \fB .mdp\fR file.
-
-\& \- \fB integrator = md\fR
-
-\& \- \fB energygrp = Protein\fR (or other group that you want to insert)
-
-\& \- \fB freezegrps = Protein\fR
-
-\& \- \fB freezedim = Y Y Y\fR
-
-\& \- \fB energygrp_excl = Protein Protein\fR
-
-\&The output is a structure file containing the protein embedded in the membrane. If a topology
-\&file is provided, the number of lipid and
-\&solvent molecules will be updated to match the new structure file.
-
-\&For a more extensive manual see Wolf et al, J Comp Chem 31 (2010) 2169\-2174, Appendix.
-
-
-\&SHORT METHOD DESCRIPTION
-
-\&\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-
-
-\&1. The protein is resized around its center of mass by a factor \fB \-xy\fR in the xy\-plane
-\&(the membrane plane) and a factor \fB \-z\fR in the \fI z\fR\-direction (if the size of the
-\&protein in the z\-direction is the same or smaller than the width of the membrane, a
-\&\fB \-z\fR value larger than 1 can prevent that the protein will be enveloped by the lipids).
-
-\&2. All lipid and solvent molecules overlapping with the resized protein are removed. All
-\&intraprotein interactions are turned off to prevent numerical issues for small values of \fB \-xy\fR
-\& or \fB \-z\fR
-
-\&3. One md step is performed.
-
-\&4. The resize factor (\fB \-xy\fR or \fB \-z\fR) is incremented by a small amount ((1\-xy)/nxy or (1\-z)/nz) and the
-\&protein is resized again around its center of mass. The resize factor for the xy\-plane
-\&is incremented first. The resize factor for the z\-direction is not changed until the \fB \-xy\fR factor
-\&is 1 (thus after \fB \-nxy\fR iterations).
-
-\&5. Repeat step 3 and 4 until the protein reaches its original size (\fB \-nxy\fR + \fB \-nz\fR iterations).
-
-\&For a more extensive method description see Wolf et al, J Comp Chem, 31 (2010) 2169\-2174.
-
-
-\&NOTE
-\-\-\-\-
-
-\& \- Protein can be any molecule you want to insert in the membrane.
-
-\& \- It is recommended to perform a short equilibration run after the embedding
-\&(see Wolf et al, J Comp Chem 31 (2010) 2169\-2174), to re\-equilibrate the membrane. Clearly
-\&protein equilibration might require longer.

-\&\fB g_mindist\fR computes the distance between one group and a number of
-\&other groups. Both the minimum distance
-\&(between any pair of atoms from the respective groups)
-\&and the number of contacts within a given
-\&distance are written to two separate output files.
-\&With the \fB \-group\fR option a contact of an atom an other group
-\&with multiple atoms in the first group is counted as one contact
-\&instead of as multiple contacts.
-\&With \fB \-or\fR, minimum distances to each residue in the first
-\&group are determined and plotted as a function of residue number.
-
-
-\&With option \fB \-pi\fR the minimum distance of a group to its
-\&periodic image is plotted. This is useful for checking if a protein
-\&has seen its periodic image during a simulation. Only one shift in
-\&each direction is considered, giving a total of 26 shifts.
-\&It also plots the maximum distance within the group and the lengths
-\&of the three box vectors.
-
-
-\&Other programs that calculate distances are \fB g_dist\fR
-\&and \fB g_bond\fR.

-.SH DESCRIPTION
-\&\fB g_morph\fR does a linear interpolation of conformations in order to
-\&create intermediates. Of course these are completely unphysical, but
-\&that you may try to justify yourself. Output is in the form of a
-\&generic trajectory. The number of intermediates can be controlled with
-\&the \fB \-ninterm\fR flag. The first and last flag correspond to the way of
-\&interpolating: 0 corresponds to input structure 1 while
-\&1 corresponds to input structure 2.
-\&If you specify \fB \-first\fR 0 or \fB \-last\fR 1 extrapolation will be
-\&on the path from input structure x1 to x2. In general, the coordinates
-\&of the intermediate x(i) out of N total intermidates correspond to:
-
-
-\&x(i) = x1 + (first+(i/(N\-1))*(last\-first))*(x2\-x1)
-
-
-\&Finally the RMSD with respect to both input structures can be computed
-\&if explicitly selected (\fB \-or\fR option). In that case, an index file may be
-\&read to select the group from which the RMS is computed.

-.SH DESCRIPTION
-\&\fB g_msd\fR computes the mean square displacement (MSD) of atoms from
-\&a set of initial positions. This provides an easy way to compute
-\&the diffusion constant using the Einstein relation.
-\&The time between the reference points for the MSD calculation
-\&is set with \fB \-trestart\fR.
-\&The diffusion constant is calculated by least squares fitting a
-\&straight line (D*t + c) through the MSD(t) from \fB \-beginfit\fR to
-\&\fB \-endfit\fR (note that t is time from the reference positions,
-\¬ simulation time). An error estimate given, which is the difference
-\&of the diffusion coefficients obtained from fits over the two halves
-\&of the fit interval.
-
-
-\&There are three, mutually exclusive, options to determine different
-\&types of mean square displacement: \fB \-type\fR, \fB \-lateral\fR
-\&and \fB \-ten\fR. Option \fB \-ten\fR writes the full MSD tensor for
-\&each group, the order in the output is: trace xx yy zz yx zx zy.
-
-
-\&If \fB \-mol\fR is set, \fB g_msd\fR plots the MSD for individual molecules
-\&(including making molecules whole across periodic boundaries):
-\&for each individual molecule a diffusion constant is computed for
-\&its center of mass. The chosen index group will be split into
-\&molecules.
-
-
-\&The default way to calculate a MSD is by using mass\-weighted averages.
-\&This can be turned off with \fB \-nomw\fR.
-
-
-\&With the option \fB \-rmcomm\fR, the center of mass motion of a
-\&specific group can be removed. For trajectories produced with
-\&GROMACS this is usually not necessary,
-\&as \fB mdrun\fR usually already removes the center of mass motion.
-\&When you use this option be sure that the whole system is stored
-\&in the trajectory file.
-
-
-\&The diffusion coefficient is determined by linear regression of the MSD,
-\&where, unlike for the normal output of D, the times are weighted
-\&according to the number of reference points, i.e. short times have
-\&a higher weight. Also when \fB \-beginfit\fR=\-1,fitting starts at 10%
-\&and when \fB \-endfit\fR=\-1, fitting goes to 90%.
-\&Using this option one also gets an accurate error estimate
-\&based on the statistics between individual molecules.
-\&Note that this diffusion coefficient and error estimate are only
-\&accurate when the MSD is completely linear between
-\&\fB \-beginfit\fR and \fB \-endfit\fR.
-
-
-\&Option \fB \-pdb\fR writes a \fB .pdb\fR file with the coordinates of the frame
-\&at time \fB \-tpdb\fR with in the B\-factor field the square root of
-\&the diffusion coefficient of the molecule.
-\&This option implies option \fB \-mol\fR.

-.SH DESCRIPTION
-\&\fB g_nmeig\fR calculates the eigenvectors/values of a (Hessian) matrix,
-\&which can be calculated with \fB mdrun\fR.
-\&The eigenvectors are written to a trajectory file (\fB \-v\fR).
-\&The structure is written first with t=0. The eigenvectors
-\&are written as frames with the eigenvector number as timestamp.
-\&The eigenvectors can be analyzed with \fB g_anaeig\fR.
-\&An ensemble of structures can be generated from the eigenvectors with
-\&\fB g_nmens\fR. When mass weighting is used, the generated eigenvectors
-\&will be scaled back to plain Cartesian coordinates before generating the
-\&output. In this case, they will no longer be exactly orthogonal in the
-\&standard Cartesian norm, but in the mass\-weighted norm they would be.
-
-
-\&This program can be optionally used to compute quantum corrections to heat capacity
-\&and enthalpy by providing an extra file argument \fB \-qcorr\fR. See the GROMACS
-\&manual, Chapter 1, for details. The result includes subtracting a harmonic
-\°ree of freedom at the given temperature.
-\&The total correction is printed on the terminal screen.
-\&The recommended way of getting the corrections out is:
-
-
-\&\fB g_nmeig \-s topol.tpr \-f nm.mtx \-first 7 \-last 10000 \-T 300 \-qc [\-constr]\fR
-
-
-\&The \fB \-constr\fR option should be used when bond constraints were used during the
-\&simulation \fB for all the covalent bonds\fR. If this is not the case,
-\&you need to analyze the \fB quant_corr.xvg\fR file yourself.
-
-
-\&To make things more flexible, the program can also take virtual sites into account
-\&when computing quantum corrections. When selecting \fB \-constr\fR and
-\&\fB \-qc\fR, the \fB \-begin\fR and \fB \-end\fR options will be set automatically as well.
-\&Again, if you think you know it better, please check the \fB eigenfreq.xvg\fR

-.SH DESCRIPTION
-\&\fB g_nmtraj\fR generates an virtual trajectory from an eigenvector,
-\&corresponding to a harmonic Cartesian oscillation around the average
-\&structure. The eigenvectors should normally be mass\-weighted, but you can
-\&use non\-weighted eigenvectors to generate orthogonal motions.
-\&The output frames are written as a trajectory file covering an entire period, and
-\&the first frame is the average structure. If you write the trajectory in (or convert to)
-\&PDB format you can view it directly in PyMol and also render a photorealistic movie.
-\&Motion amplitudes are calculated from the eigenvalues and a preset temperature,
-\&assuming equipartition of the energy over all modes. To make the motion clearly visible
-\&in PyMol you might want to amplify it by setting an unrealistically high temperature.
-\&However, be aware that both the linear Cartesian displacements and mass weighting will
-\&lead to serious structure deformation for high amplitudes \- this is is simply a limitation
-\&of the Cartesian normal mode model. By default the selected eigenvector is set to 7, since
-\& the first six normal modes are the translational and rotational degrees of freedom.

-\- If the configuration script found Motif or Lesstif on your system, you can use the graphical interface (if not, you will get an error):
-\fB \-X\fR gmx_bool \fB no\fR Use dialog box GUI to edit command line options
-
-\- When compiled on an SGI\-IRIX system, all GROMACS programs have an additional option:
-\fB \-npri\fR int \fB 0\fR Set non blocking priority (try 128)
-
-\- Optional files are not used unless the option is set, in contrast to non\-optional files, where the default file name is used when the option is not set.
-
-\- All GROMACS programs will accept file options without a file extension or filename being specified. In such cases the default filenames will be used. With multiple input file types, such as generic structure format, the directory will be searched for files of each type with the supplied or default name. When no such file is found, or with output files the first file type will be used.
-
-\- All GROMACS programs with the exception of \fB mdrun\fR and \fB eneconv\fR check if the command line options are valid. If this is not the case, the program will be halted.
-
-\- Enumerated options (enum) should be used with one of the arguments listed in the option description, the argument may be abbreviated. The first match to the shortest argument in the list will be selected.
-
-\- Vector options can be used with 1 or 3 parameters. When only one parameter is supplied the two others are also set to this value.
-
-\- All GROMACS programs can read compressed or g\-zipped files. There might be a problem with reading compressed \fB .xtc\fR, \fB .trr\fR and \fB .trj\fR files, but these will not compress very well anyway.
-
-\- Most GROMACS programs can process a trajectory with fewer atoms than the run input or structure file, but only if the trajectory consists of the first n atoms of the run input or structure file.
-
-\- Many GROMACS programs will accept the \fB \-tu\fR option to set the time units to use in output files (e.g. for \fB xmgr\fR graphs or \fB xpm\fR matrices) and in all time options.

-.SH DESCRIPTION
-\&Compute the order parameter per atom for carbon tails. For atom i the
-\&vector i\-1, i+1 is used together with an axis.
-\&The index file should contain only the groups to be used for calculations,
-\&with each group of equivalent carbons along the relevant acyl chain in its own
-\&group. There should not be any generic groups (like System, Protein) in the index
-\&file to avoid confusing the program (this is not relevant to tetrahedral order
-\¶meters however, which only work for water anyway).
-
-
-\&The program can also give all
-\&diagonal elements of the order tensor and even calculate the deuterium
-\&order parameter Scd (default). If the option \fB \-szonly\fR is given, only one
-\&order tensor component (specified by the \fB \-d\fR option) is given and the
-\&order parameter per slice is calculated as well. If \fB \-szonly\fR is not
-\&selected, all diagonal elements and the deuterium order parameter is
-\&given.
-
-The tetrahedrality order parameters can be determined
-\&around an atom. Both angle an distance order parameters are calculated. See
-\&P.\-L. Chau and A.J. Hardwick, Mol. Phys., 93, (1998), 511\-518.

-\&For the radius of gyration the total and the three principal components
-\&for the average gyration tensor are written.
-\&With option \fB \-v\fR the eigenvectors are written.
-\&With option \fB \-pc\fR also the average eigenvalues of the individual

-\&With option \fB \-i\fR the mean square internal distances are

-
-
-\&With option \fB \-p\fR the persistence length is determined.
-\&The chosen index group should consist of atoms that are
-\&consecutively bonded in the polymer mainchains.
-\&The persistence length is then determined from the cosine of
-\&the angles between bonds with an index difference that is even,
-\&the odd pairs are not used, because straight polymer backbones
-\&are usually all trans and therefore only every second bond aligns.
-\&The persistence length is defined as number of bonds where
-\&the average cos reaches a value of 1/e. This point is determined
-\&by a linear interpolation of log(cos).

-.SH DESCRIPTION
-\&The structure of liquids can be studied by either neutron or X\-ray
-\&scattering. The most common way to describe liquid structure is by a
-\&radial distribution function. However, this is not easy to obtain from
-\&a scattering experiment.
-
-
-\&\fB g_rdf\fR calculates radial distribution functions in different ways.
-\&The normal method is around a (set of) particle(s), the other methods
-\&are around the center of mass of a set of particles (\fB \-com\fR)
-\&or to the closest particle in a set (\fB \-surf\fR).
-\&With all methods, the RDF can also be calculated around axes parallel
-\&to the \fI z\fR\-axis with option \fB \-xy\fR.
-\&With option \fB \-surf\fR normalization can not be used.
-
-
-\&The option \fB \-rdf\fR sets the type of RDF to be computed.
-\&Default is for atoms or particles, but one can also select center
-\&of mass or geometry of molecules or residues. In all cases, only
-\&the atoms in the index groups are taken into account.
-\&For molecules and/or the center of mass option, a run input file
-\&is required.
-\&Weighting other than COM or COG can currently only be achieved
-\&by providing a run input file with different masses.
-\&Options \fB \-com\fR and \fB \-surf\fR also work in conjunction
-\&with \fB \-rdf\fR.
-
-
-\&If a run input file is supplied (\fB \-s\fR) and \fB \-rdf\fR is set
-\&to \fB atom\fR, exclusions defined
-\&in that file are taken into account when calculating the RDF.
-\&The option \fB \-cut\fR is meant as an alternative way to avoid
-\&intramolecular peaks in the RDF plot.
-\&It is however better to supply a run input file with a higher number of
-\&exclusions. For e.g. benzene a topology, setting nrexcl to 5
-\&would eliminate all intramolecular contributions to the RDF.
-\&Note that all atoms in the selected groups are used, also the ones
-\&that don't have Lennard\-Jones interactions.
-
-
-\&Option \fB \-cn\fR produces the cumulative number RDF,
-\&i.e. the average number of particles within a distance r.
-
-
-\&To bridge the gap between theory and experiment structure factors can
-\&be computed (option \fB \-sq\fR). The algorithm uses FFT, the grid
-\&spacing of which is determined by option \fB \-grid\fR.

-.SH DESCRIPTION
-\&\fB g_rms\fR compares two structures by computing the root mean square
-\&deviation (RMSD), the size\-independent rho similarity parameter
-\&(\fB rho\fR) or the scaled rho (\fB rhosc\fR),
-\&see Maiorov & Crippen, Proteins \fB 22\fR, 273 (1995).
-\&This is selected by \fB \-what\fR.
-
-Each structure from a trajectory (\fB \-f\fR) is compared to a
-\&reference structure. The reference structure
-\&is taken from the structure file (\fB \-s\fR).
-
-
-\&With option \fB \-mir\fR also a comparison with the mirror image of
-\&the reference structure is calculated.
-\&This is useful as a reference for 'significant' values, see
-\&Maiorov & Crippen, Proteins \fB 22\fR, 273 (1995).
-
-
-\&Option \fB \-prev\fR produces the comparison with a previous frame
-\&the specified number of frames ago.
-
-
-\&Option \fB \-m\fR produces a matrix in \fB .xpm\fR format of
-\&comparison values of each structure in the trajectory with respect to
-\&each other structure. This file can be visualized with for instance
-\&\fB xv\fR and can be converted to postscript with \fB xpm2ps\fR.
-
-
-\&Option \fB \-fit\fR controls the least\-squares fitting of
-\&the structures on top of each other: complete fit (rotation and
-\&translation), translation only, or no fitting at all.
-
-
-\&Option \fB \-mw\fR controls whether mass weighting is done or not.
-\&If you select the option (default) and
-\&supply a valid \fB .tpr\fR file masses will be taken from there,
-\&otherwise the masses will be deduced from the \fB atommass.dat\fR file in
-\&\fB GMXLIB\fR. This is fine for proteins, but not
-\&necessarily for other molecules. A default mass of 12.011 amu (carbon)
-\&is assigned to unknown atoms. You can check whether this happend by
-\&turning on the \fB \-debug\fR flag and inspecting the log file.
-
-
-\&With \fB \-f2\fR, the 'other structures' are taken from a second
-\&trajectory, this generates a comparison matrix of one trajectory
-\&versus the other.
-
-
-\&Option \fB \-bin\fR does a binary dump of the comparison matrix.
-
-
-\&Option \fB \-bm\fR produces a matrix of average bond angle deviations
-\&analogously to the \fB \-m\fR option. Only bonds between atoms in the
-\&comparison group are considered.

-\&\fB g_rmsdist\fR computes the root mean square deviation of atom distances,

-\&The reference structure is taken from the structure file.
-\&The RMSD at time t is calculated as the RMS

-\&structure and the structure at time t.
-
-
-\&\fB g_rmsdist\fR can also produce matrices of the rms distances, rms distances
-\&scaled with the mean distance and the mean distances and matrices with
-\&NMR averaged distances (1/r3 and 1/r6 averaging). Finally, lists
-\&of atom pairs with 1/r3 and 1/r6 averaged distance below the

-\&can be generated, by default averaging over equivalent hydrogens
-\&(all triplets of hydrogens named *[123]). Additionally a list of
-\&equivalent atoms can be supplied (\fB \-equiv\fR), each line containing
-\&a set of equivalent atoms specified as residue number and name and
-\&atom name; e.g.:
-
-
-\&\fB 3 SER HB1 3 SER HB2\fR
-
-
-\&Residue and atom names must exactly match those in the structure

-\&\fB g_rmsf\fR computes the root mean square fluctuation (RMSF, i.e. standard
-\&deviation) of atomic positions in the trajectory (supplied with \fB \-f\fR)
-\&after (optionally) fitting to a reference frame (supplied with \fB \-s\fR).
-
-
-\&With option \fB \-oq\fR the RMSF values are converted to B\-factor
-\&values, which are written to a \fB .pdb\fR file with the coordinates, of the
-\&structure file, or of a \fB .pdb\fR file when \fB \-q\fR is specified.
-\&Option \fB \-ox\fR writes the B\-factors to a file with the average
-\&coordinates.
-
-
-\&With the option \fB \-od\fR the root mean square deviation with
-\&respect to the reference structure is calculated.
-
-
-\&With the option \fB \-aniso\fR, \fB g_rmsf\fR will compute anisotropic
-\&temperature factors and then it will also output average coordinates
-\&and a \fB .pdb\fR file with ANISOU records (corresonding to the \fB \-oq\fR
-\&or \fB \-ox\fR option). Please note that the U values
-\&are orientation\-dependent, so before comparison with experimental data
-\&you should verify that you fit to the experimental coordinates.
-
-
-\&When a \fB .pdb\fR input file is passed to the program and the \fB \-aniso\fR
-\&flag is set
-\&a correlation plot of the Uij will be created, if any anisotropic
-\&temperature factors are present in the \fB .pdb\fR file.
-
-
-\&With option \fB \-dir\fR the average MSF (3x3) matrix is diagonalized.
-\&This shows the directions in which the atoms fluctuate the most and
-\&the least.

-.SH DESCRIPTION
-\&\fB g_rotacf\fR calculates the rotational correlation function
-\&for molecules. Three atoms (i,j,k) must be given in the index
-\&file, defining two vectors ij and jk. The rotational ACF
-\&is calculated as the autocorrelation function of the vector
-\&n = ij x jk, i.e. the cross product of the two vectors.
-\&Since three atoms span a plane, the order of the three atoms
-\&does not matter. Optionally, controlled by the \fB \-d\fR switch, you can
-\&calculate the rotational correlation function for linear molecules
-\&by specifying two atoms (i,j) in the index file.

-
-
-\&This will calculate the rotational correlation function using a first
-\&order Legendre polynomial of the angle of a vector defined by the index
-\&file. The correlation function will be fitted from 2.5 ps until 20.0 ps
-\&to a two\-parameter exponential.

-.SH DESCRIPTION
-\&\fB g_rotmat\fR plots the rotation matrix required for least squares fitting
-\&a conformation onto the reference conformation provided with
-\&\fB \-s\fR. Translation is removed before fitting.
-\&The output are the three vectors that give the new directions
-\&of the x, y and z directions of the reference conformation,
-\&for example: (zx,zy,zz) is the orientation of the reference
-\&z\-axis in the trajectory frame.
-\&
-
-
-\&This tool is useful for, for instance,
-\&determining the orientation of a molecule
-\&at an interface, possibly on a trajectory produced with
-\&\fB trjconv \-fit rotxy+transxy\fR to remove the rotation
-\&in the \fI x\-y\fR plane.
-\&
-
-
-\&Option \fB \-ref\fR determines a reference structure for fitting,
-\&instead of using the structure from \fB \-s\fR. The structure with
-\&the lowest sum of RMSD's to all other structures is used.
-\&Since the computational cost of this procedure grows with
-\&the square of the number of frames, the \fB \-skip\fR option
-\&can be useful. A full fit or only a fit in the \fI x\-y\fR plane can
-\&be performed.
-\&
-
-
-\&Option \fB \-fitxy\fR fits in the \fI x\-y\fR plane before determining
-\&the rotation matrix.

-\&\fB g_sas\fR computes hydrophobic, hydrophilic and total solvent accessible surface area.
-\&As a side effect, the Connolly surface can be generated as well in
-\&a \fB .pdb\fR file where the nodes are represented as atoms and the vertices
-\&connecting the nearest nodes as CONECT records.
-\&The program will ask for a group for the surface calculation
-\&and a group for the output. The calculation group should always
-\&consists of all the non\-solvent atoms in the system.
-\&The output group can be the whole or part of the calculation group.
-\&The average and standard deviation of the area over the trajectory can be plotted
-\&per residue and atom as well (options \fB \-or\fR and \fB \-oa\fR).
-\&In combination with the latter option an \fB .itp\fR file can be
-\&generated (option \fB \-i\fR)
-\&which can be used to restrain surface atoms.
-
-
-\&By default, periodic boundary conditions are taken into account,
-\&this can be turned off using the \fB \-nopbc\fR option.
-
-
-\&With the \fB \-tv\fR option the total volume and density of the molecule can be
-\&computed.
-\&Please consider whether the normal probe radius is appropriate
-\&in this case or whether you would rather use e.g. 0. It is good
-\&to keep in mind that the results for volume and density are very
-\&approximate. For example, in ice Ih, one can easily fit water molecules in the
-\&pores which would yield a volume that is too low, and surface area and density
-\&that are both too high.

-\&\fB g_select\fR writes out basic data about dynamic selections.
-\&It can be used for some simple analyses, or the output can
-\&be combined with output from other programs and/or external
-\&analysis programs to calculate more complex things.
-\&Any combination of the output options is possible, but note
-\&that \fB \-om\fR only operates on the first selection.
-
-
-\&With \fB \-os\fR, calculates the number of positions in each
-\&selection for each frame. With \fB \-norm\fR, the output is
-\&between 0 and 1 and describes the fraction from the maximum
-\&number of positions (e.g., for selection 'resname RA and x 5'
-\&the maximum number of positions is the number of atoms in
-\&RA residues). With \fB \-cfnorm\fR, the output is divided
-\&by the fraction covered by the selection.
-\&\fB \-norm\fR and \fB \-cfnorm\fR can be specified independently
-\&of one another.
-
-
-\&With \fB \-oc\fR, the fraction covered by each selection is
-\&written out as a function of time.
-
-
-\&With \fB \-oi\fR, the selected atoms/residues/molecules are
-\&written out as a function of time. In the output, the first
-\&column contains the frame time, the second contains the number
-\&of positions, followed by the atom/residue/molecule numbers.
-\&If more than one selection is specified, the size of the second
-\&group immediately follows the last number of the first group
-\&and so on. With \fB \-dump\fR, the frame time and the number
-\&of positions is omitted from the output. In this case, only one
-\&selection can be given.
-
-
-\&With \fB \-on\fR, the selected atoms are written as a index file
-\&compatible with \fB make_ndx\fR and the analyzing tools. Each selection
-\&is written as a selection group and for dynamic selections a
-\&group is written for each frame.
-
-
-\&For residue numbers, the output of \fB \-oi\fR can be controlled
-\&with \fB \-resnr\fR: \fB number\fR (default) prints the residue
-\&numbers as they appear in the input file, while \fB index\fR prints
-\&unique numbers assigned to the residues in the order they appear
-\&in the input file, starting with 1. The former is more intuitive,
-\&but if the input contains multiple residues with the same number,
-\&the output can be less useful.
-
-
-\&With \fB \-om\fR, a mask is printed for the first selection
-\&as a function of time. Each line in the output corresponds to
-\&one frame, and contains either 0/1 for each atom/residue/molecule
-\&possibly selected. 1 stands for the atom/residue/molecule being
-\&selected for the current frame, 0 for not selected.
-\&With \fB \-dump\fR, the frame time is omitted from the output.

-.SH DESCRIPTION
-\&Compute the angle and distance between two groups.
-\&The groups are defined by a number of atoms given in an index file and
-\&may be two or three atoms in size.
-\&If \fB \-one\fR is set, only one group should be specified in the index
-\&file and the angle between this group at time 0 and t will be computed.
-\&The angles calculated depend on the order in which the atoms are
-\&given. Giving, for instance, 5 6 will rotate the vector 5\-6 with
-\&180 degrees compared to giving 6 5.
-
-If three atoms are given,
-\&the normal on the plane spanned by those three atoms will be
-\&calculated, using the formula P1P2 x P1P3.
-\&The cos of the angle is calculated, using the inproduct of the two
-\&normalized vectors.
-
-
-\&Here is what some of the file options do:
-
-\&\fB \-oa\fR: Angle between the two groups specified in the index file. If a group contains three atoms the normal to the plane defined by those three atoms will be used. If a group contains two atoms, the vector defined by those two atoms will be used.
-
-\&\fB \-od\fR: Distance between two groups. Distance is taken from the center of one group to the center of the other group.
-
-\&\fB \-od1\fR: If one plane and one vector is given, the distances for each of the atoms from the center of the plane is given separately.
-
-\&\fB \-od2\fR: For two planes this option has no meaning.

-.SH DESCRIPTION
-\&\fB g_sham\fR makes multi\-dimensional free\-energy, enthalpy and entropy plots.
-\&\fB g_sham\fR reads one or more \fB .xvg\fR files and analyzes data sets.
-\&The basic purpose of \fB g_sham\fR is to plot Gibbs free energy landscapes
-\&(option \fB \-ls\fR)
-\&by Bolzmann inverting multi\-dimensional histograms (option \fB \-lp\fR),
-\&but it can also
-\&make enthalpy (option \fB \-lsh\fR) and entropy (option \fB \-lss\fR)
-\&plots. The histograms can be made for any quantities the user supplies.
-\&A line in the input file may start with a time
-\&(see option \fB \-time\fR) and any number of \fI y\fR\-values may follow.
-\&Multiple sets can also be
-\&read when they are separated by & (option \fB \-n\fR),
-\&in this case only one \fI y\fR\-value is read from each line.
-\&All lines starting with and @ are skipped.
-\&
-
-
-\&Option \fB \-ge\fR can be used to supply a file with free energies
-\&when the ensemble is not a Boltzmann ensemble, but needs to be biased
-\&by this free energy. One free energy value is required for each
-\&(multi\-dimensional) data point in the \fB \-f\fR input.
-\&
-
-
-\&Option \fB \-ene\fR can be used to supply a file with energies.
-\&These energies are used as a weighting function in the single
-\&histogram analysis method by Kumar et al. When temperatures
-\&are supplied (as a second column in the file), an experimental
-\&weighting scheme is applied. In addition the vales
-\&are used for making enthalpy and entropy plots.
-\&
-
-
-\&With option \fB \-dim\fR, dimensions can be gives for distances.
-\&When a distance is 2\- or 3\-dimensional, the circumference or surface
-\&sampled by two particles increases with increasing distance.
-\&Depending on what one would like to show, one can choose to correct
-\&the histogram and free\-energy for this volume effect.
-\&The probability is normalized by r and r2 for dimensions of 2 and 3,
-\&respectively.
-\&A value of \-1 is used to indicate an angle in degrees between two
-\&vectors: a sin(angle) normalization will be applied.
-\&\fB Note\fR that for angles between vectors the inner\-product or cosine
-\&is the natural quantity to use, as it will produce bins of the same
-\&volume.

-\&\fB g_sorient\fR analyzes solvent orientation around solutes.
-\&It calculates two angles between the vector from one or more
-\&reference positions to the first atom of each solvent molecule:
-
-
-\&theta1: the angle with the vector from the first atom of the solvent
-\&molecule to the midpoint between atoms 2 and 3.
-
-\&theta2: the angle with the normal of the solvent plane, defined by the
-\&same three atoms, or, when the option \fB \-v23\fR is set,
-\&the angle with the vector between atoms 2 and 3.
-
-
-\&The reference can be a set of atoms or
-\&the center of mass of a set of atoms. The group of solvent atoms should
-\&consist of 3 atoms per solvent molecule.
-\&Only solvent molecules between \fB \-rmin\fR and \fB \-rmax\fR are
-\&considered for \fB \-o\fR and \fB \-no\fR each frame.
-
-
-\&\fB \-o\fR: distribtion of cos(theta1) for rmin=r=rmax.
-
-
-\&\fB \-no\fR: distribution of cos(theta2) for rmin=r=rmax.
-
-
-\&\fB \-ro\fR: cos(theta1) and 3cos2(theta2)\-1 as a function of the
-\&distance.
-
-

-.SH DESCRIPTION
-\&\fB g_spatial\fR calculates the spatial distribution function and
-\&outputs it in a form that can be read by VMD as Gaussian98 cube format.
-\&This was developed from template.c (GROMACS\-3.3).
-\&For a system of 32,000 atoms and a 50 ns trajectory, the SDF can be generated
-\&in about 30 minutes, with most of the time dedicated to the two runs through
-\&\fB trjconv\fR that are required to center everything properly.
-\&This also takes a whole bunch of space (3 copies of the \fB .xtc\fR file).
-\&Still, the pictures are pretty and very informative when the fitted selection is properly made.
-\&3\-4 atoms in a widely mobile group (like a free amino acid in solution) works
-\&well, or select the protein backbone in a stable folded structure to get the SDF
-\&of solvent and look at the time\-averaged solvation shell.
-\&It is also possible using this program to generate the SDF based on some arbitrary
-\&Cartesian coordinate. To do that, simply omit the preliminary \fB trjconv\fR steps.
-
-\&USAGE:
-
-\&1. Use \fB make_ndx\fR to create a group containing the atoms around which you want the SDF
-
-\&2. \fB trjconv \-s a.tpr \-f a.xtc \-o b.xtc \-center tric \-ur compact \-pbc none\fR
-
-\&3. \fB trjconv \-s a.tpr \-f b.xtc \-o c.xtc \-fit rot+trans\fR
-
-\&4. run \fB g_spatial\fR on the \fB .xtc\fR output of step 3.
-
-\&5. Load \fB grid.cube\fR into VMD and view as an isosurface.
-
-\&\fB Note\fR that systems such as micelles will require \fB trjconv \-pbc cluster\fR between steps 1 and 2
-
-\&WARNINGS:
-
-\&The SDF will be generated for a cube that contains all bins that have some non\-zero occupancy.
-\&However, the preparatory \fB \-fit rot+trans\fR option to \fB trjconv\fR implies that your system will be rotating
-\&and translating in space (in order that the selected group does not). Therefore the values that are
-\&returned will only be valid for some region around your central group/coordinate that has full overlap
-\&with system volume throughout the entire translated/rotated system over the course of the trajectory.
-\&It is up to the user to ensure that this is the case.
-
-\&BUGS:
-
-\&When the allocated memory is not large enough, a segmentation fault may occur. This is usually detected
-\&and the program is halted prior to the fault while displaying a warning message suggesting the use of the \fB \-nab\fR (Number of Additional Bins)
-\&option. However, the program does not detect all such events. If you encounter a segmentation fault, run it again
-\&with an increased \fB \-nab\fR value.
-
-\&RISKY OPTIONS:
-
-\&To reduce the amount of space and time required, you can output only the coords
-\&that are going to be used in the first and subsequent run through \fB trjconv\fR.
-\&However, be sure to set the \fB \-nab\fR option to a sufficiently high value since
-\&memory is allocated for cube bins based on the initial coordinates and the \fB \-nab\fR
-\&option value.

-.SH DESCRIPTION
-\&\fB g_spol\fR analyzes dipoles around a solute; it is especially useful
-\&for polarizable water. A group of reference atoms, or a center
-\&of mass reference (option \fB \-com\fR) and a group of solvent
-\&atoms is required. The program splits the group of solvent atoms
-\&into molecules. For each solvent molecule the distance to the
-\&closest atom in reference group or to the COM is determined.
-\&A cumulative distribution of these distances is plotted.
-\&For each distance between \fB \-rmin\fR and \fB \-rmax\fR
-\&the inner product of the distance vector
-\&and the dipole of the solvent molecule is determined.
-\&For solvent molecules with net charge (ions), the net charge of the ion
-\&is subtracted evenly from all atoms in the selection of each ion.
-\&The average of these dipole components is printed.
-\&The same is done for the polarization, where the average dipole is
-\&subtracted from the instantaneous dipole. The magnitude of the average
-\&dipole is set with the option \fB \-dip\fR, the direction is defined
-\&by the vector from the first atom in the selected solvent group
-\&to the midpoint between the second and the third atom.

-.SH DESCRIPTION
-\&\fB g_tcaf\fR computes tranverse current autocorrelations.
-\&These are used to estimate the shear viscosity, eta.
-\&For details see: Palmer, Phys. Rev. E 49 (1994) pp 359\-366.
-
-
-\&Transverse currents are calculated using the
-\&k\-vectors (1,0,0) and (2,0,0) each also in the \fI y\fR\- and \fI z\fR\-direction,
-\&(1,1,0) and (1,\-1,0) each also in the 2 other planes (these vectors
-\&are not independent) and (1,1,1) and the 3 other box diagonals (also
-\¬ independent). For each k\-vector the sine and cosine are used, in
-\&combination with the velocity in 2 perpendicular directions. This gives
-\&a total of 16*2*2=64 transverse currents. One autocorrelation is
-\&calculated fitted for each k\-vector, which gives 16 TCAF's. Each of
-\&these TCAF's is fitted to f(t) = exp(\-v)(cosh(Wv) + 1/W sinh(Wv)),
-\&v = \-t/(2 tau), W = sqrt(1 \- 4 tau eta/rho k2), which gives 16 values of tau
-\&and eta. The fit weights decay with time as exp(\-t/wt), and the TCAF and
-\&fit are calculated up to time 5*wt.
-\&The eta values should be fitted to 1 \- a eta(k) k2, from which
-\&one can estimate the shear viscosity at k=0.
-
-
-\&When the box is cubic, one can use the option \fB \-oc\fR, which
-\&averages the TCAF's over all k\-vectors with the same length.
-\&This results in more accurate tcaf's.
-\&Both the cubic TCAF's and fits are written to \fB \-oc\fR
-\&The cubic eta estimates are also written to \fB \-ov\fR.
-
-
-\&With option \fB \-mol\fR, the transverse current is determined of
-\&molecules instead of atoms. In this case, the index group should
-\&consist of molecule numbers instead of atom numbers.
-
-
-\&The k\-dependent viscosities in the \fB \-ov\fR file should be
-\&fitted to eta(k) = eta0 (1 \- a k2) to obtain the viscosity at
-\&infinite wavelength.
-
-
-\&\fB Note:\fR make sure you write coordinates and velocities often enough.
-\&The initial, non\-exponential, part of the autocorrelation function
-\&is very important for obtaining a good fit.

-.SH DESCRIPTION
-\&\fB g_traj\fR plots coordinates, velocities, forces and/or the box.
-\&With \fB \-com\fR the coordinates, velocities and forces are
-\&calculated for the center of mass of each group.
-\&When \fB \-mol\fR is set, the numbers in the index file are
-\&interpreted as molecule numbers and the same procedure as with
-\&\fB \-com\fR is used for each molecule.
-
-
-\&Option \fB \-ot\fR plots the temperature of each group,
-\&provided velocities are present in the trajectory file.
-\&No corrections are made for constrained degrees of freedom!
-\&This implies \fB \-com\fR.
-
-
-\&Options \fB \-ekt\fR and \fB \-ekr\fR plot the translational and
-\&rotational kinetic energy of each group,
-\&provided velocities are present in the trajectory file.
-\&This implies \fB \-com\fR.
-
-
-\&Options \fB \-cv\fR and \fB \-cf\fR write the average velocities
-\&and average forces as temperature factors to a \fB .pdb\fR file with
-\&the average coordinates or the coordinates at \fB \-ctime\fR.
-\&The temperature factors are scaled such that the maximum is 10.
-\&The scaling can be changed with the option \fB \-scale\fR.
-\&To get the velocities or forces of one
-\&frame set both \fB \-b\fR and \fB \-e\fR to the time of
-\&desired frame. When averaging over frames you might need to use
-\&the \fB \-nojump\fR option to obtain the correct average coordinates.
-\&If you select either of these option the average force and velocity
-\&for each atom are written to an \fB .xvg\fR file as well
-\&(specified with \fB \-av\fR or \fB \-af\fR).
-
-
-\&Option \fB \-vd\fR computes a velocity distribution, i.e. the
-\&norm of the vector is plotted. In addition in the same graph
-\&the kinetic energy distribution is given.

-.SH DESCRIPTION
-\&For a given number \fB \-np\fR or \fB \-nt\fR of processors/threads, this program systematically
-\× \fB mdrun\fR with various numbers of PME\-only nodes and determines
-\&which setting is fastest. It will also test whether performance can
-\&be enhanced by shifting load from the reciprocal to the real space
-\&part of the Ewald sum.
-\&Simply pass your \fB .tpr\fR file to \fB g_tune_pme\fR together with other options
-\&for \fB mdrun\fR as needed.
-
-
-\&Which executables are used can be set in the environment variables
-\&MPIRUN and MDRUN. If these are not present, 'mpirun' and 'mdrun'
-\&will be used as defaults. Note that for certain MPI frameworks you
-\&need to provide a machine\- or hostfile. This can also be passed
-\&via the MPIRUN variable, e.g.
-
-
-\&\fB export MPIRUN="/usr/local/mpirun \-machinefile hosts"\fR
-
-
-\&Please call \fB g_tune_pme\fR with the normal options you would pass to
-\&\fB mdrun\fR and add \fB \-np\fR for the number of processors to perform the
-\&tests on, or \fB \-nt\fR for the number of threads. You can also add \fB \-r\fR
-\&to repeat each test several times to get better statistics.
-
-
-\&\fB g_tune_pme\fR can test various real space / reciprocal space workloads
-\&for you. With \fB \-ntpr\fR you control how many extra \fB .tpr\fR files will be
-\&written with enlarged cutoffs and smaller fourier grids respectively.
-\&Typically, the first test (number 0) will be with the settings from the input
-\&\fB .tpr\fR file; the last test (number \fB ntpr\fR) will have cutoffs multiplied
-\&by (and at the same time fourier grid dimensions divided by) the scaling
-\&factor \fB \-fac\fR (default 1.2). The remaining \fB .tpr\fR files will have about
-\&equally\-spaced values in between these extremes. \fB Note\fR that you can set \fB \-ntpr\fR to 1
-\&if you just want to find the optimal number of PME\-only nodes; in that case
-\&your input \fB .tpr\fR file will remain unchanged.
-
-
-\&For the benchmark runs, the default of 1000 time steps should suffice for most
-\&MD systems. The dynamic load balancing needs about 100 time steps
-\&to adapt to local load imbalances, therefore the time step counters
-\&are by default reset after 100 steps. For large systems
-\&(1M atoms) you may have to set \fB \-resetstep\fR to a higher value.
-\&From the 'DD' load imbalance entries in the md.log output file you
-\&can tell after how many steps the load is sufficiently balanced. Example call:
-
-\fB g_tune_pme \-np 64 \-s protein.tpr \-launch\fR
-
-
-\&After calling \fB mdrun\fR several times, detailed performance information
-\&is available in the output file \fB perf.out.\fR
-\&\fB Note\fR that during the benchmarks, a couple of temporary files are written
-\&(options \fB \-b\fR*), these will be automatically deleted after each test.
-
-
-\&If you want the simulation to be started automatically with the
-\&optimized parameters, use the command line option \fB \-launch\fR.

-.SH DESCRIPTION
-\&\fB g_vanhove\fR computes the Van Hove correlation function.
-\&The Van Hove G(r,t) is the probability that a particle that is at r0
-\&at time zero can be found at position r0+r at time t.
-\&\fB g_vanhove\fR determines G not for a vector r, but for the length of r.
-\&Thus it gives the probability that a particle moves a distance of r
-\&in time t.
-\&Jumps across the periodic boundaries are removed.
-\&Corrections are made for scaling due to isotropic
-\&or anisotropic pressure coupling.
-\&
-
-
-\&With option \fB \-om\fR the whole matrix can be written as a function
-\&of t and r or as a function of sqrt(t) and r (option \fB \-sqrt\fR).
-\&
-
-
-\&With option \fB \-or\fR the Van Hove function is plotted for one
-\&or more values of t. Option \fB \-nr\fR sets the number of times,
-\&option \fB \-fr\fR the number spacing between the times.
-\&The binwidth is set with option \fB \-rbin\fR. The number of bins
-\&is determined automatically.
-\&
-
-
-\&With option \fB \-ot\fR the integral up to a certain distance
-\&(option \fB \-rt\fR) is plotted as a function of time.
-\&
-
-
-\&For all frames that are read the coordinates of the selected particles
-\&are stored in memory. Therefore the program may use a lot of memory.
-\&For options \fB \-om\fR and \fB \-ot\fR the program may be slow.
-\&This is because the calculation scales as the number of frames times
-\&\fB \-fm\fR or \fB \-ft\fR.
-\&Note that with the \fB \-dt\fR option the memory usage and calculation
-\&time can be reduced.

-.SH DESCRIPTION
-\&This is an analysis program that implements the Weighted
-\&Histogram Analysis Method (WHAM). It is intended to analyze
-\&output files generated by umbrella sampling simulations to
-\&compute a potential of mean force (PMF).
-
-
-\&At present, three input modes are supported.
-
-\&\fB *\fR With option \fB \-it\fR, the user provides a file which contains the
-\& file names of the umbrella simulation run\-input files (\fB .tpr\fR files),
-\& AND, with option \fB \-ix\fR, a file which contains file names of
-\& the pullx \fB mdrun\fR output files. The \fB .tpr\fR and pullx files must
-\& be in corresponding order, i.e. the first \fB .tpr\fR created the
-\& first pullx, etc.
-
-\&\fB *\fR Same as the previous input mode, except that the the user
-\& provides the pull force output file names (\fB pullf.xvg\fR) with option \fB \-if\fR.
-\& From the pull force the position in the umbrella potential is
-\& computed. This does not work with tabulated umbrella potentials.
-\fB *\fR With option \fB \-ip\fR, the user provides file names of (gzipped) \fB .pdo\fR files, i.e.
-\& the GROMACS 3.3 umbrella output files. If you have some unusual reaction coordinate you may also generate your own \fB .pdo\fR files and
-\& feed them with the \fB \-ip\fR option into to \fB g_wham\fR. The \fB .pdo\fR file header
-\& must be similar to the following:
-
-
-\&\fB UMBRELLA 3.0
-
-\& Component selection: 0 0 1
-
-\& nSkip 1
-
-\& Ref. Group 'TestAtom'
-
-\& Nr. of pull groups 2
-
-\& Group 1 'GR1' Umb. Pos. 5.0 Umb. Cons. 1000.0
-
-\& Group 2 'GR2' Umb. Pos. 2.0 Umb. Cons. 500.0
-
-\&\fR
-
-
-\&The number of pull groups, umbrella positions, force constants, and names
-\&may (of course) differ. Following the header, a time column and
-\&a data column for each pull group follows (i.e. the displacement
-\&with respect to the umbrella center). Up to four pull groups are possible
-\&per \fB .pdo\fR file at present.
-
-
-\&By default, the output files are
-
-\& \fB \-o\fR PMF output file
-
-\& \fB \-hist\fR Histograms output file
-
-\&Always check whether the histograms sufficiently overlap.
-
-
-\&The umbrella potential is assumed to be harmonic and the force constants are
-\&read from the \fB .tpr\fR or \fB .pdo\fR files. If a non\-harmonic umbrella force was applied
-\&a tabulated potential can be provided with \fB \-tab\fR.
-
-
-\&WHAM OPTIONS
-\-\-\-\-\-\-\-\-\-\-\-\-
-
-\& \fB \-bins\fR Number of bins used in analysis
-
-\& \fB \-temp\fR Temperature in the simulations
-
-\& \fB \-tol\fR Stop iteration if profile (probability) changed less than tolerance
-
-\& \fB \-auto\fR Automatic determination of boundaries
-
-\& \fB \-min,\-max\fR Boundaries of the profile
-
-\&The data points that are used to compute the profile
-\&can be restricted with options \fB \-b\fR, \fB \-e\fR, and \fB \-dt\fR.
-\&Adjust \fB \-b\fR to ensure sufficient equilibration in each
-\&umbrella window.
-
-
-\&With \fB \-log\fR (default) the profile is written in energy units, otherwise
-\&(with \fB \-nolog\fR) as probability. The unit can be specified with \fB \-unit\fR.
-\&With energy output, the energy in the first bin is defined to be zero.
-\&If you want the free energy at a different
-\&position to be zero, set \fB \-zprof0\fR (useful with bootstrapping, see below).
-
-
-\&For cyclic or periodic reaction coordinates (dihedral angle, channel PMF
-\&without osmotic gradient), the option \fB \-cycl\fR is useful. \fB g_wham\fR will make use of the
-\&periodicity of the system and generate a periodic PMF. The first and the last bin of the
-\&reaction coordinate will assumed be be neighbors.
-
-
-\&Option \fB \-sym\fR symmetrizes the profile around z=0 before output,
-\&which may be useful for, e.g. membranes.
-
-
-\&AUTOCORRELATIONS
-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-
-
-\&With \fB \-ac\fR, \fB g_wham\fR estimates the integrated autocorrelation
-\&time (IACT) tau for each umbrella window and weights the respective
-\&window with 1/[1+2*tau/dt]. The IACTs are written
-\&to the file defined with \fB \-oiact\fR. In verbose mode, all
-\&autocorrelation functions (ACFs) are written to \fB hist_autocorr.xvg\fR.
-\&Because the IACTs can be severely underestimated in case of limited
-\&sampling, option \fB \-acsig\fR allows to smooth the IACTs along the
-\&reaction coordinate with a Gaussian (sigma provided with \fB \-acsig\fR,
-\&see output in \fB iact.xvg\fR). Note that the IACTs are estimated by simple
-\&integration of the ACFs while the ACFs are larger 0.05.
-\&If you prefer to compute the IACTs by a more sophisticated (but possibly
-\&less robust) method such as fitting to a double exponential, you can
-\&compute the IACTs with \fB g_analyze\fR and provide them to \fB g_wham\fR with the file
-\&\fB iact\-in.dat\fR (option \fB \-iiact\fR), which should contain one line per
-\&input file (\fB .pdo\fR or pullx/f file) and one column per pull group in the respective file.
-
-
-\&ERROR ANALYSIS
-\-\-\-\-\-\-\-\-\-\-\-\-\-\-
-
-\&Statistical errors may be estimated with bootstrap analysis. Use it with care,
-\&otherwise the statistical error may be substantially underestimated.
-\&More background and examples for the bootstrap technique can be found in
-\&Hub, de Groot and Van der Spoel, JCTC (2010) 6: 3713\-3720.
-
-\&\fB \-nBootstrap\fR defines the number of bootstraps (use, e.g., 100).
-\&Four bootstrapping methods are supported and
-\&selected with \fB \-bs\-method\fR.
-
-\& (1) \fB b\-hist\fR Default: complete histograms are considered as independent
-\&data points, and the bootstrap is carried out by assigning random weights to the
-\&histograms ("Bayesian bootstrap"). Note that each point along the reaction coordinate
-\&must be covered by multiple independent histograms (e.g. 10 histograms), otherwise the
-\&statistical error is underestimated.
-
-\& (2) \fB hist\fR Complete histograms are considered as independent data points.
-\&For each bootstrap, N histograms are randomly chosen from the N given histograms
-\&(allowing duplication, i.e. sampling with replacement).
-\&To avoid gaps without data along the reaction coordinate blocks of histograms
-\&(\fB \-histbs\-block\fR) may be defined. In that case, the given histograms are
-\÷d into blocks and only histograms within each block are mixed. Note that
-\&the histograms within each block must be representative for all possible histograms,
-\&otherwise the statistical error is underestimated.
-
-\& (3) \fB traj\fR The given histograms are used to generate new random trajectories,
-\&such that the generated data points are distributed according the given histograms
-\&and properly autocorrelated. The autocorrelation time (ACT) for each window must be
-\&known, so use \fB \-ac\fR or provide the ACT with \fB \-iiact\fR. If the ACT of all
-\&windows are identical (and known), you can also provide them with \fB \-bs\-tau\fR.
-\&Note that this method may severely underestimate the error in case of limited sampling,
-\&that is if individual histograms do not represent the complete phase space at
-\&the respective positions.
-
-\& (4) \fB traj\-gauss\fR The same as method \fB traj\fR, but the trajectories are
-\¬ bootstrapped from the umbrella histograms but from Gaussians with the average
-\&and width of the umbrella histograms. That method yields similar error estimates
-\&like method \fB traj\fR.
-
-Bootstrapping output:
-
-\& \fB \-bsres\fR Average profile and standard deviations
-
-\& \fB \-bsprof\fR All bootstrapping profiles
-
-\&With \fB \-vbs\fR (verbose bootstrapping), the histograms of each bootstrap are written,
-\&and, with bootstrap method \fB traj\fR, the cumulative distribution functions of
-\&the histograms.

-\&\fB g_x2top\fR generates a primitive topology from a coordinate file.
-\&The program assumes all hydrogens are present when defining
-\&the hybridization from the atom name and the number of bonds.
-\&The program can also make an \fB .rtp\fR entry, which you can then add
-\&to the \fB .rtp\fR database.
-
-
-\&When \fB \-param\fR is set, equilibrium distances and angles
-\&and force constants will be printed in the topology for all
-\&interactions. The equilibrium distances and angles are taken
-\&from the input coordinates, the force constant are set with
-\&command line options.
-\&The force fields somewhat supported currently are:
-
-
-\&G53a5 GROMOS96 53a5 Forcefield (official distribution)
-
-
-\&oplsaa OPLS\-AA/L all\-atom force field (2001 aminoacid dihedrals)
-
-
-\&The corresponding data files can be found in the library directory
-\&with name \fB atomname2type.n2t\fR. Check Chapter 5 of the manual for more
-\&information about file formats. By default, the force field selection
-\&is interactive, but you can use the \fB \-ff\fR option to specify
-\&one of the short names above on the command line instead. In that
-\&case \fB g_x2top\fR just looks for the corresponding file.

-.SH DESCRIPTION
-\&\fB genbox\fR can do one of 3 things:
-
-
-\&1) Generate a box of solvent. Specify \fB \-cs\fR and \fB \-box\fR. Or specify \fB \-cs\fR and
-\&\fB \-cp\fR with a structure file with a box, but without atoms.
-
-
-\&2) Solvate a solute configuration, e.g. a protein, in a bath of solvent
-\&molecules. Specify \fB \-cp\fR (solute) and \fB \-cs\fR (solvent).
-\&The box specified in the solute coordinate file (\fB \-cp\fR) is used,
-\&unless \fB \-box\fR is set.
-\&If you want the solute to be centered in the box,
-\&the program \fB editconf\fR has sophisticated options
-\&to change the box dimensions and center the solute.
-\&Solvent molecules are removed from the box where the
-\&distance between any atom of the solute molecule(s) and any atom of
-\&the solvent molecule is less than the sum of the van der Waals radii of
-\&both atoms. A database (\fB vdwradii.dat\fR) of van der Waals radii is
-\&read by the program, and atoms not in the database are
-\&assigned a default distance \fB \-vdwd\fR.
-\&Note that this option will also influence the distances between
-\&solvent molecules if they contain atoms that are not in the database.
-\&
-
-
-\&3) Insert a number (\fB \-nmol\fR) of extra molecules (\fB \-ci\fR)
-\&at random positions.
-\&The program iterates until \fB nmol\fR molecules
-\&have been inserted in the box. To test whether an insertion is
-\&successful the same van der Waals criterium is used as for removal of
-\&solvent molecules. When no appropriately\-sized
-\&holes (holes that can hold an extra molecule) are available, the
-\&program tries for \fB \-nmol\fR * \fB \-try\fR times before giving up.
-\&Increase \fB \-try\fR if you have several small holes to fill.
-
-
-\&If you need to do more than one of the above operations, it can be
-\&best to call \fB genbox\fR separately for each operation, so that
-\&you are sure of the order in which the operations occur.
-
-
-\&The default solvent is Simple Point Charge water (SPC), with coordinates
-\&from \fB $GMXLIB/spc216.gro\fR. These coordinates can also be used
-\&for other 3\-site water models, since a short equibilibration will remove
-\&the small differences between the models.
-\&Other solvents are also supported, as well as mixed solvents. The
-\&only restriction to solvent types is that a solvent molecule consists
-\&of exactly one residue. The residue information in the coordinate
-\&files is used, and should therefore be more or less consistent.
-\&In practice this means that two subsequent solvent molecules in the
-\&solvent coordinate file should have different residue number.
-\&The box of solute is built by stacking the coordinates read from
-\&the coordinate file. This means that these coordinates should be
-\&equlibrated in periodic boundary conditions to ensure a good
-\&alignment of molecules on the stacking interfaces.
-\&The \fB \-maxsol\fR option simply adds only the first \fB \-maxsol\fR
-\&solvent molecules and leaves out the rest would have fit into the box.
-\&
-
-
-\&The program can optionally rotate the solute molecule to align the
-\&longest molecule axis along a box edge. This way the amount of solvent
-\&molecules necessary is reduced.
-\&It should be kept in mind that this only works for
-\&short simulations, as e.g. an alpha\-helical peptide in solution can
-\&rotate over 90 degrees, within 500 ps. In general it is therefore
-\&better to make a more or less cubic box.
-
-
-\&Setting \fB \-shell\fR larger than zero will place a layer of water of
-\&the specified thickness (nm) around the solute. Hint: it is a good
-\&idea to put the protein in the center of a box first (using \fB editconf\fR).
-\&
-
-
-\&Finally, \fB genbox\fR will optionally remove lines from your topology file in
-\&which a number of solvent molecules is already added, and adds a
-\&line with the total number of solvent molecules in your coordinate file.

-.SH DESCRIPTION
-\&\fB genion\fR replaces solvent molecules by monoatomic ions at
-\&the position of the first atoms with the most favorable electrostatic
-\&potential or at random. The potential is calculated on all atoms, using
-\&normal GROMACS particle\-based methods (in contrast to other methods
-\&based on solving the Poisson\-Boltzmann equation).
-\&The potential is recalculated after every ion insertion.
-\&If specified in the run input file, a reaction field, shift function
-\&or user function can be used. For the user function a table file
-\&can be specified with the option \fB \-table\fR.
-\&The group of solvent molecules should be continuous and all molecules
-\&should have the same number of atoms.
-\&The user should add the ion molecules to the topology file or use
-\&the \fB \-p\fR option to automatically modify the topology.
-
-
-\&The ion molecule type, residue and atom names in all force fields
-\&are the capitalized element names without sign. This molecule name
-\&should be given with \fB \-pname\fR or \fB \-nname\fR, and the
-\&\fB [molecules]\fR section of your topology updated accordingly,
-\&either by hand or with \fB \-p\fR. Do not use an atom name instead!
-\&
-
-Ions which can have multiple charge states get the multiplicity
-\&added, without sign, for the uncommon states only.
-
-
-\&With the option \fB \-pot\fR the potential can be written as B\-factors
-\&in a \fB .pdb\fR file (for visualisation using e.g. Rasmol).
-\&The unit of the potential is 1000 kJ/(mol e), the scaling be changed
-\&with the \fB \-scale\fR option.
-
-
-\&For larger ions, e.g. sulfate we recommended using \fB genbox\fR.

-\&\fB genrestr\fR produces an include file for a topology containing

-
-
-\&WARNING: position restraints only work for the one molecule at a time.
-\&Position restraints are interactions within molecules, therefore

-\&block in the topology. Since the atom numbers in every moleculetype
-\&in the topology start at 1 and the numbers in the input file for

-
-
-\&The \fB \-of\fR option produces an index file that can be used for
-\&freezing atoms. In this case, the input file must be a \fB .pdb\fR file.
-
-
-\&With the \fB \-disre\fR option, half a matrix of distance restraints
-\&is generated instead of position restraints. With this matrix, that

-.SH DESCRIPTION
-\&The gromacs preprocessor
-\&reads a molecular topology file, checks the validity of the
-\&file, expands the topology from a molecular description to an atomic
-\&description. The topology file contains information about
-\&molecule types and the number of molecules, the preprocessor
-\&copies each molecule as needed.
-\&There is no limitation on the number of molecule types.
-\&Bonds and bond\-angles can be converted into constraints, separately
-\&for hydrogens and heavy atoms.
-\&Then a coordinate file is read and velocities can be generated
-\&from a Maxwellian distribution if requested.
-\&\fB grompp\fR also reads parameters for the \fB mdrun\fR
-\&(eg. number of MD steps, time step, cut\-off), and others such as
-\&NEMD parameters, which are corrected so that the net acceleration
-\&is zero.
-\&Eventually a binary file is produced that can serve as the sole input
-\&file for the MD program.
-
-
-\&\fB grompp\fR uses the atom names from the topology file. The atom names
-\&in the coordinate file (option \fB \-c\fR) are only read to generate
-\&warnings when they do not match the atom names in the topology.
-\&Note that the atom names are irrelevant for the simulation as
-\&only the atom types are used for generating interaction parameters.
-
-
-\&\fB grompp\fR uses a built\-in preprocessor to resolve includes, macros,
-\&etc. The preprocessor supports the following keywords:
-
-
-\&ifdef VARIABLE
-
-\&ifndef VARIABLE
-
-\&else
-
-\&endif
-
-\&define VARIABLE
-
-\&undef VARIABLE
-include "filename"
-
-\&include filename
-
-
-\&The functioning of these statements in your topology may be modulated by
-\&using the following two flags in your \fB .mdp\fR file:
-
-
-\&\fB define = \-DVARIABLE1 \-DVARIABLE2
-
-\&include = \-I/home/john/doe\fR
-
-\&For further information a C\-programming textbook may help you out.
-\&Specifying the \fB \-pp\fR flag will get the pre\-processed
-\&topology file written out so that you can verify its contents.
-
-
-\&When using position restraints a file with restraint coordinates
-\&can be supplied with \fB \-r\fR, otherwise restraining will be done
-\&with respect to the conformation from the \fB \-c\fR option.
-\&For free energy calculation the the coordinates for the B topology
-\&can be supplied with \fB \-rb\fR, otherwise they will be equal to
-\&those of the A topology.
-
-
-\&Starting coordinates can be read from trajectory with \fB \-t\fR.
-\&The last frame with coordinates and velocities will be read,
-\&unless the \fB \-time\fR option is used. Only if this information
-\&is absent will the coordinates in the \fB \-c\fR file be used.
-\&Note that these velocities will not be used when \fB gen_vel = yes\fR
-\&in your \fB .mdp\fR file. An energy file can be supplied with
-\&\fB \-e\fR to read Nose\-Hoover and/or Parrinello\-Rahman coupling
-\&variables.
-
-
-\&\fB grompp\fR can be used to restart simulations (preserving
-\&continuity) by supplying just a checkpoint file with \fB \-t\fR.
-\&However, for simply changing the number of run steps to extend
-\&a run, using \fB tpbconv\fR is more convenient than \fB grompp\fR.
-\&You then supply the old checkpoint file directly to \fB mdrun\fR
-\&with \fB \-cpi\fR. If you wish to change the ensemble or things
-\&like output frequency, then supplying the checkpoint file to
-\&\fB grompp\fR with \fB \-t\fR along with a new \fB .mdp\fR file
-\&with \fB \-f\fR is the recommended procedure.
-
-
-\&By default, all bonded interactions which have constant energy due to
-\&virtual site constructions will be removed. If this constant energy is
-\¬ zero, this will result in a shift in the total energy. All bonded
-\&interactions can be kept by turning off \fB \-rmvsbds\fR. Additionally,
-\&all constraints for distances which will be constant anyway because
-\&of virtual site constructions will be removed. If any constraints remain
-\&which involve virtual sites, a fatal error will result.
-
-To verify your run input file, please take note of all warnings
-\&on the screen, and correct where necessary. Do also look at the contents
-\&of the \fB mdout.mdp\fR file; this contains comment lines, as well as
-\&the input that \fB grompp\fR has read. If in doubt, you can start \fB grompp\fR
-\&with the \fB \-debug\fR option which will give you more information
-\&in a file called \fB grompp.log\fR (along with real debug info). You
-\&can see the contents of the run input file with the \fB gmxdump\fR
-\&program. \fB gmxcheck\fR can be used to compare the contents of two
-\&run input files.
-
-The \fB \-maxwarn\fR option can be used to override warnings printed
-\&by \fB grompp\fR that otherwise halt output. In some cases, warnings are
-\&harmless, but usually they are not. The user is advised to carefully
-\&interpret the output messages before attempting to bypass them with
-\&this option.

-.SH DESCRIPTION
-\&\fB make_edi\fR generates an essential dynamics (ED) sampling input file to be used with \fB mdrun\fR
-\&based on eigenvectors of a covariance matrix (\fB g_covar\fR) or from a
-\&normal modes anaysis (\fB g_nmeig\fR).
-\&ED sampling can be used to manipulate the position along collective coordinates
-\&(eigenvectors) of (biological) macromolecules during a simulation. Particularly,
-\&it may be used to enhance the sampling efficiency of MD simulations by stimulating
-\&the system to explore new regions along these collective coordinates. A number
-\&of different algorithms are implemented to drive the system along the eigenvectors
-\&(\fB \-linfix\fR, \fB \-linacc\fR, \fB \-radfix\fR, \fB \-radacc\fR, \fB \-radcon\fR),
-\&to keep the position along a certain (set of) coordinate(s) fixed (\fB \-linfix\fR),
-\&or to only monitor the projections of the positions onto
-\&these coordinates (\fB \-mon\fR).

-
-You will be prompted for one or more index groups that correspond to the eigenvectors,
-\&reference structure, target positions, etc.
-
-
-\&\fB \-mon\fR: monitor projections of the coordinates onto selected eigenvectors.
-
-
-\&\fB \-linfix\fR: perform fixed\-step linear expansion along selected eigenvectors.
-
-
-\&\fB \-linacc\fR: perform acceptance linear expansion along selected eigenvectors.
-\&(steps in the desired directions will be accepted, others will be rejected).
-
-
-\&\fB \-radfix\fR: perform fixed\-step radius expansion along selected eigenvectors.
-
-
-\&\fB \-radacc\fR: perform acceptance radius expansion along selected eigenvectors.
-\&(steps in the desired direction will be accepted, others will be rejected).
-\&\fB Note:\fR by default the starting MD structure will be taken as origin of the first
-\&expansion cycle for radius expansion. If \fB \-ori\fR is specified, you will be able
-\&to read in a structure file that defines an external origin.
-
-
-\&\fB \-radcon\fR: perform acceptance radius contraction along selected eigenvectors
-\&towards a target structure specified with \fB \-tar\fR.
-
-
-\&NOTE: each eigenvector can be selected only once.
-
-
-\&\fB \-outfrq\fR: frequency (in steps) of writing out projections etc. to \fB .edo\fR file
-
-
-\&\fB \-slope\fR: minimal slope in acceptance radius expansion. A new expansion
-\&cycle will be started if the spontaneous increase of the radius (in nm/step)
-\&is less than the value specified.
-
-
-\&\fB \-maxedsteps\fR: maximum number of steps per cycle in radius expansion
-\&before a new cycle is started.
-
-
-\&Note on the parallel implementation: since ED sampling is a 'global' thing
-\&(collective coordinates etc.), at least on the 'protein' side, ED sampling
-\&is not very parallel\-friendly from an implentation point of view. Because
-\¶llel ED requires some extra communication, expect the performance to be
-\&lower as in a free MD simulation, especially on a large number of nodes.
-
-
-\&All output of \fB mdrun\fR (specify with \fB \-eo\fR) is written to a .edo file. In the output
-\&file, per OUTFRQ step the following information is present:
-
-
-\&\fB *\fR the step number
-
-\&\fB *\fR the number of the ED dataset. (\fB Note\fR that you can impose multiple ED constraints in
-\&a single simulation (on different molecules) if several \fB .edi\fR files were concatenated
-\&first. The constraints are applied in the order they appear in the \fB .edi\fR file.)
-
-\&\fB *\fR RMSD (for atoms involved in fitting prior to calculating the ED constraints)
-
-\&* projections of the positions onto selected eigenvectors
-
-\&
-
-
-
-
-\&FLOODING:
-
-
-\&with \fB \-flood\fR, you can specify which eigenvectors are used to compute a flooding potential,
-\&which will lead to extra forces expelling the structure out of the region described
-\&by the covariance matrix. If you switch \-restrain the potential is inverted and the structure
-\&is kept in that region.
-\&
-
-
-\&The origin is normally the average structure stored in the \fB eigvec.trr\fR file.
-\&It can be changed with \fB \-ori\fR to an arbitrary position in configurational space.
-\&With \fB \-tau\fR, \fB \-deltaF0\fR, and \fB \-Eflnull\fR you control the flooding behaviour.
-\&Efl is the flooding strength, it is updated according to the rule of adaptive flooding.
-\&Tau is the time constant of adaptive flooding, high tau means slow adaption (i.e. growth).
-\&DeltaF0 is the flooding strength you want to reach after tau ps of simulation.
-\&To use constant Efl set \fB \-tau\fR to zero.
-\&
-
-
-\&\fB \-alpha\fR is a fudge parameter to control the width of the flooding potential. A value of 2 has been found
-\&to give good results for most standard cases in flooding of proteins.
-\&alpha basically accounts for incomplete sampling, if you sampled further the width of the ensemble would
-\&increase, this is mimicked by alpha 1.
-\&For restraining, alpha 1 can give you smaller width in the restraining potential.
-\&
-
-
-\&RESTART and FLOODING:
-\&If you want to restart a crashed flooding simulation please find the values deltaF and Efl in
-\&the output file and manually put them into the \fB .edi\fR file under DELTA_F0 and EFL_NULL.

-.SH DESCRIPTION
-\&The \fB mdrun\fR program is the main computational chemistry engine
-\&within GROMACS. Obviously, it performs Molecular Dynamics simulations,
-\&but it can also perform Stochastic Dynamics, Energy Minimization,
-\&test particle insertion or (re)calculation of energies.
-\&Normal mode analysis is another option. In this case \fB mdrun\fR
-\&builds a Hessian matrix from single conformation.
-\&For usual Normal Modes\-like calculations, make sure that
-\&the structure provided is properly energy\-minimized.
-\&The generated matrix can be diagonalized by \fB g_nmeig\fR.
-
-
-\&The \fB mdrun\fR program reads the run input file (\fB \-s\fR)
-\&and distributes the topology over nodes if needed.
-\&\fB mdrun\fR produces at least four output files.
-\&A single log file (\fB \-g\fR) is written, unless the option
-\&\fB \-seppot\fR is used, in which case each node writes a log file.
-\&The trajectory file (\fB \-o\fR), contains coordinates, velocities and
-\&optionally forces.
-\&The structure file (\fB \-c\fR) contains the coordinates and
-\&velocities of the last step.
-\&The energy file (\fB \-e\fR) contains energies, the temperature,
-\&pressure, etc, a lot of these things are also printed in the log file.
-\&Optionally coordinates can be written to a compressed trajectory file
-\&(\fB \-x\fR).
-
-
-\&The option \fB \-dhdl\fR is only used when free energy calculation is
-\&turned on.
-
-
-\&When \fB mdrun\fR is started using MPI with more than 1 node, parallelization
-\&is used. By default domain decomposition is used, unless the \fB \-pd\fR
-\&option is set, which selects particle decomposition.
-
-
-\&With domain decomposition, the spatial decomposition can be set
-\&with option \fB \-dd\fR. By default \fB mdrun\fR selects a good decomposition.
-\&The user only needs to change this when the system is very inhomogeneous.
-\&Dynamic load balancing is set with the option \fB \-dlb\fR,
-\&which can give a significant performance improvement,
-\&especially for inhomogeneous systems. The only disadvantage of
-\&dynamic load balancing is that runs are no longer binary reproducible,
-\&but in most cases this is not important.
-\&By default the dynamic load balancing is automatically turned on
-\&when the measured performance loss due to load imbalance is 5% or more.
-\&At low parallelization these are the only important options
-\&for domain decomposition.
-\&At high parallelization the options in the next two sections
-\&could be important for increasing the performace.
-\&
-
-
-\&When PME is used with domain decomposition, separate nodes can
-\&be assigned to do only the PME mesh calculation;
-\&this is computationally more efficient starting at about 12 nodes.
-\&The number of PME nodes is set with option \fB \-npme\fR,
-\&this can not be more than half of the nodes.
-\&By default \fB mdrun\fR makes a guess for the number of PME
-\&nodes when the number of nodes is larger than 11 or performance wise
-\¬ compatible with the PME grid x dimension.
-\&But the user should optimize npme. Performance statistics on this issue
-\&are written at the end of the log file.
-\&For good load balancing at high parallelization, the PME grid x and y
-\&dimensions should be divisible by the number of PME nodes
-\&(the simulation will run correctly also when this is not the case).
-\&
-
-
-\&This section lists all options that affect the domain decomposition.
-\&
-
-
-\&Option \fB \-rdd\fR can be used to set the required maximum distance
-\&for inter charge\-group bonded interactions.
-\&Communication for two\-body bonded interactions below the non\-bonded
-\&cut\-off distance always comes for free with the non\-bonded communication.
-\&Atoms beyond the non\-bonded cut\-off are only communicated when they have
-\&missing bonded interactions; this means that the extra cost is minor
-\&and nearly indepedent of the value of \fB \-rdd\fR.
-\&With dynamic load balancing option \fB \-rdd\fR also sets
-\&the lower limit for the domain decomposition cell sizes.
-\&By default \fB \-rdd\fR is determined by \fB mdrun\fR based on
-\&the initial coordinates. The chosen value will be a balance
-\&between interaction range and communication cost.
-\&
-
-
-\&When inter charge\-group bonded interactions are beyond
-\&the bonded cut\-off distance, \fB mdrun\fR terminates with an error message.
-\&For pair interactions and tabulated bonds
-\&that do not generate exclusions, this check can be turned off
-\&with the option \fB \-noddcheck\fR.
-\&
-
-
-\&When constraints are present, option \fB \-rcon\fR influences
-\&the cell size limit as well.
-\&Atoms connected by NC constraints, where NC is the LINCS order plus 1,
-\&should not be beyond the smallest cell size. A error message is
-\&generated when this happens and the user should change the decomposition
-\&or decrease the LINCS order and increase the number of LINCS iterations.
-\&By default \fB mdrun\fR estimates the minimum cell size required for P\-LINCS
-\&in a conservative fashion. For high parallelization it can be useful
-\&to set the distance required for P\-LINCS with the option \fB \-rcon\fR.
-\&
-
-
-\&The \fB \-dds\fR option sets the minimum allowed x, y and/or z scaling
-\&of the cells with dynamic load balancing. \fB mdrun\fR will ensure that
-\&the cells can scale down by at least this factor. This option is used
-\&for the automated spatial decomposition (when not using \fB \-dd\fR)
-\&as well as for determining the number of grid pulses, which in turn
-\&sets the minimum allowed cell size. Under certain circumstances
-\&the value of \fB \-dds\fR might need to be adjusted to account for
-\&high or low spatial inhomogeneity of the system.
-\&
-
-
-\&The option \fB \-gcom\fR can be used to only do global communication
-\&every n steps.
-\&This can improve performance for highly parallel simulations
-\&where this global communication step becomes the bottleneck.
-\&For a global thermostat and/or barostat the temperature
-\&and/or pressure will also only be updated every \fB \-gcom\fR steps.
-\&By default it is set to the minimum of nstcalcenergy and nstlist.
-
-
-\&With \fB \-rerun\fR an input trajectory can be given for which
-\&forces and energies will be (re)calculated. Neighbor searching will be
-\&performed for every frame, unless \fB nstlist\fR is zero
-\&(see the \fB .mdp\fR file).
-
-
-\&ED (essential dynamics) sampling is switched on by using the \fB \-ei\fR
-\&flag followed by an \fB .edi\fR file.
-\&The \fB .edi\fR file can be produced using options in the essdyn
-\&menu of the WHAT IF program. \fB mdrun\fR produces a \fB .edo\fR file that
-\&contains projections of positions, velocities and forces onto selected
-\&eigenvectors.
-
-
-\&When user\-defined potential functions have been selected in the
-\&\fB .mdp\fR file the \fB \-table\fR option is used to pass \fB mdrun\fR
-\&a formatted table with potential functions. The file is read from
-\&either the current directory or from the \fB GMXLIB\fR directory.
-\&A number of pre\-formatted tables are presented in the \fB GMXLIB\fR dir,
-\&for 6\-8, 6\-9, 6\-10, 6\-11, 6\-12 Lennard\-Jones potentials with
-\&normal Coulomb.
-\&When pair interactions are present, a separate table for pair interaction
-\&functions is read using the \fB \-tablep\fR option.
-
-
-\&When tabulated bonded functions are present in the topology,
-\&interaction functions are read using the \fB \-tableb\fR option.
-\&For each different tabulated interaction type the table file name is
-\&modified in a different way: before the file extension an underscore is
-\&appended, then a 'b' for bonds, an 'a' for angles or a 'd' for dihedrals
-\&and finally the table number of the interaction type.
-
-
-\&The options \fB \-px\fR and \fB \-pf\fR are used for writing pull COM
-\&coordinates and forces when pulling is selected
-\&in the \fB .mdp\fR file.
-
-
-\&With \fB \-multi\fR or \fB \-multidir\fR, multiple systems can be
-\&simulated in parallel.
-\&As many input files/directories are required as the number of systems.
-\&The \fB \-multidir\fR option takes a list of directories (one for each
-\&system) and runs in each of them, using the input/output file names,
-\&such as specified by e.g. the \fB \-s\fR option, relative to these
-\&directories.
-\&With \fB \-multi\fR, the system number is appended to the run input
-\&and each output filename, for instance \fB topol.tpr\fR becomes
-\&\fB topol0.tpr\fR, \fB topol1.tpr\fR etc.
-\&The number of nodes per system is the total number of nodes
-\÷d by the number of systems.
-\&One use of this option is for NMR refinement: when distance
-\&or orientation restraints are present these can be ensemble averaged
-\&over all the systems.
-
-
-\&With \fB \-replex\fR replica exchange is attempted every given number
-\&of steps. The number of replicas is set with the \fB \-multi\fR or
-\&\fB \-multidir\fR option, described above.
-\&All run input files should use a different coupling temperature,
-\&the order of the files is not important. The random seed is set with
-\&\fB \-reseed\fR. The velocities are scaled and neighbor searching
-\&is performed after every exchange.
-
-
-\&Finally some experimental algorithms can be tested when the
-\&appropriate options have been given. Currently under
-\&investigation are: polarizability and X\-ray bombardments.
-\&
-
-
-\&The option \fB \-pforce\fR is useful when you suspect a simulation
-\&crashes due to too large forces. With this option coordinates and
-\&forces of atoms with a force larger than a certain value will
-\&be printed to stderr.
-\&
-
-
-\&Checkpoints containing the complete state of the system are written
-\&at regular intervals (option \fB \-cpt\fR) to the file \fB \-cpo\fR,
-\&unless option \fB \-cpt\fR is set to \-1.
-\&The previous checkpoint is backed up to \fB state_prev.cpt\fR to
-\&make sure that a recent state of the system is always available,
-\&even when the simulation is terminated while writing a checkpoint.
-\&With \fB \-cpnum\fR all checkpoint files are kept and appended
-\&with the step number.
-\&A simulation can be continued by reading the full state from file
-\&with option \fB \-cpi\fR. This option is intelligent in the way that
-\&if no checkpoint file is found, Gromacs just assumes a normal run and
-\&starts from the first step of the \fB .tpr\fR file. By default the output
-\&will be appending to the existing output files. The checkpoint file
-\&contains checksums of all output files, such that you will never
-\&loose data when some output files are modified, corrupt or removed.
-\&There are three scenarios with \fB \-cpi\fR:
-
-
-\&\fB *\fR no files with matching names are present: new output files are written
-
-
-\&\fB *\fR all files are present with names and checksums matching those stored
-\&in the checkpoint file: files are appended
-
-
-\&\fB *\fR otherwise no files are modified and a fatal error is generated
-
-
-\&With \fB \-noappend\fR new output files are opened and the simulation
-\&part number is added to all output file names.
-\&Note that in all cases the checkpoint file itself is not renamed
-\&and will be overwritten, unless its name does not match
-\&the \fB \-cpo\fR option.
-\&
-
-
-\&With checkpointing the output is appended to previously written
-\&output files, unless \fB \-noappend\fR is used or none of the previous
-\&output files are present (except for the checkpoint file).
-\&The integrity of the files to be appended is verified using checksums
-\&which are stored in the checkpoint file. This ensures that output can
-\¬ be mixed up or corrupted due to file appending. When only some
-\&of the previous output files are present, a fatal error is generated
-\&and no old output files are modified and no new output files are opened.
-\&The result with appending will be the same as from a single run.
-\&The contents will be binary identical, unless you use a different number
-\&of nodes or dynamic load balancing or the FFT library uses optimizations
-\&through timing.
-\&
-
-
-\&With option \fB \-maxh\fR a simulation is terminated and a checkpoint
-\&file is written at the first neighbor search step where the run time
-\&exceeds \fB \-maxh\fR*0.99 hours.
-\&
-
-
-\&When \fB mdrun\fR receives a TERM signal, it will set nsteps to the current
-\&step plus one. When \fB mdrun\fR receives an INT signal (e.g. when ctrl+C is
-\&pressed), it will stop after the next neighbor search step
-\&(with nstlist=0 at the next step).
-\&In both cases all the usual output will be written to file.
-\&When running with MPI, a signal to one of the \fB mdrun\fR processes
-\&is sufficient, this signal should not be sent to mpirun or
-\&the \fB mdrun\fR process that is the parent of the others.
-\&
-
-
-\&When \fB mdrun\fR is started with MPI, it does not run niced by default.

-\&These files can subsequently be processed to generate a run input file.
-\&
-
-
-\&\fB pdb2gmx\fR will search for force fields by looking for
-\&a \fB forcefield.itp\fR file in subdirectories \fB forcefield.ff\fR
-\&of the current working directory and of the Gromacs library directory
-\&as inferred from the path of the binary or the \fB GMXLIB\fR environment
-\&variable.
-\&By default the forcefield selection is interactive,
-\&but you can use the \fB \-ff\fR option to specify one of the short names
-\&in the list on the command line instead. In that case \fB pdb2gmx\fR just looks
-\&for the corresponding \fB forcefield.ff\fR directory.
-\&
-
-
-\&After choosing a force field, all files will be read only from
-\&the corresponding force field directory.
-\&If you want to modify or add a residue types, you can copy the force
-\&field directory from the Gromacs library directory to your current
-\&working directory. If you want to add new protein residue types,
-\&you will need to modify \fB residuetypes.dat\fR in the library directory
-\&or copy the whole library directory to a local directory and set
-\&the environment variable \fB GMXLIB\fR to the name of that directory.
-\&Check Chapter 5 of the manual for more information about file formats.
-\&
-
-
-\&Note that a \fB .pdb\fR file is nothing more than a file format, and it
-\&need not necessarily contain a protein structure. Every kind of
-\&molecule for which there is support in the database can be converted.
-\&If there is no support in the database, you can add it yourself.
-
-
-\&The program has limited intelligence, it reads a number of database
-\&files, that allow it to make special bonds (Cys\-Cys, Heme\-His, etc.),
-\&if necessary this can be done manually. The program can prompt the
-\&user to select which kind of LYS, ASP, GLU, CYS or HIS residue she
-\&wants. For LYS the choice is between neutral (two protons on NZ) or
-\&protonated (three protons, default), for ASP and GLU unprotonated
-\&(default) or protonated, for HIS the proton can be either on ND1,
-\&on NE2 or on both. By default these selections are done automatically.
-\&For His, this is based on an optimal hydrogen bonding
-\&conformation. Hydrogen bonds are defined based on a simple geometric
-\&criterion, specified by the maximum hydrogen\-donor\-acceptor angle
-\&and donor\-acceptor distance, which are set by \fB \-angle\fR and
-\&\fB \-dist\fR respectively.
-
-
-\&The separation of chains is not entirely trivial since the markup
-\&in user\-generated PDB files frequently varies and sometimes it
-\&is desirable to merge entries across a TER record, for instance
-\&if you want a disulfide bridge or distance restraints between
-\&two protein chains or if you have a HEME group bound to a protein.
-\&In such cases multiple chains should be contained in a single
-\&\fB moleculetype\fR definition.
-\&To handle this, \fB pdb2gmx\fR has an option \fB \-chainsep\fR so you can
-\&choose whether a new chain should start when we find a TER record,
-\&when the chain id changes, combinations of either or both of these
-\&or fully interactively.
-
-
-\&\fB pdb2gmx\fR will also check the occupancy field of the \fB .pdb\fR file.
-\&If any of the occupancies are not one, indicating that the atom is
-\¬ resolved well in the structure, a warning message is issued.
-\&When a \fB .pdb\fR file does not originate from an X\-ray structure determination
-\&all occupancy fields may be zero. Either way, it is up to the user
-\&to verify the correctness of the input data (read the article!).
-
-
-\&During processing the atoms will be reordered according to GROMACS
-\&conventions. With \fB \-n\fR an index file can be generated that
-\&contains one group reordered in the same way. This allows you to
-\&convert a GROMOS trajectory and coordinate file to GROMOS. There is
-\&one limitation: reordering is done after the hydrogens are stripped
-\&from the input and before new hydrogens are added. This means that
-\&you should not use \fB \-ignh\fR.
-
-
-\&The \fB .gro\fR and \fB .g96\fR file formats do not support chain
-\&identifiers. Therefore it is useful to enter a \fB .pdb\fR file name at
-\&the \fB \-o\fR option when you want to convert a multi\-chain \fB .pdb\fR file.
-\&
-
-
-\&The option \fB \-vsite\fR removes hydrogen and fast improper dihedral
-\&motions. Angular and out\-of\-plane motions can be removed by changing
-\&hydrogens into virtual sites and fixing angles, which fixes their
-\&position relative to neighboring atoms. Additionally, all atoms in the
-\&aromatic rings of the standard amino acids (i.e. PHE, TRP, TYR and HIS)
-\&can be converted into virtual sites, eliminating the fast improper dihedral
-\&fluctuations in these rings. \fB Note\fR that in this case all other hydrogen
-\&atoms are also converted to virtual sites. The mass of all atoms that are
-\&converted into virtual sites, is added to the heavy atoms.
-
-
-\&Also slowing down of dihedral motion can be done with \fB \-heavyh\fR
-\&done by increasing the hydrogen\-mass by a factor of 4. This is also
-\&done for water hydrogens to slow down the rotational motion of water.
-\&The increase in mass of the hydrogens is subtracted from the bonded
-\&(heavy) atom so that the total mass of the system remains the same.

-\&\fB trjcat\fR concatenates several input trajectory files in sorted order.

-
-
-\&One important option is inferred when the output file is amongst the

-.SH DESCRIPTION
-\&\fB trjconv\fR can convert trajectory files in many ways:
-
-\&\fB 1.\fR from one format to another
-
-\&\fB 2.\fR select a subset of atoms
-
-\&\fB 3.\fR change the periodicity representation
-
-\&\fB 4.\fR keep multimeric molecules together
-
-\&\fB 5.\fR center atoms in the box
-
-\&\fB 6.\fR fit atoms to reference structure
-
-\&\fB 7.\fR reduce the number of frames
-
-\&\fB 8.\fR change the timestamps of the frames
-\&(\fB \-t0\fR and \fB \-timestep\fR)
-
-\&\fB 9.\fR cut the trajectory in small subtrajectories according
-\&to information in an index file. This allows subsequent analysis of
-\&the subtrajectories that could, for example, be the result of a
-\&cluster analysis. Use option \fB \-sub\fR.
-\&This assumes that the entries in the index file are frame numbers and
-\&dumps each group in the index file to a separate trajectory file.
-
-\&\fB 10.\fR select frames within a certain range of a quantity given
-\&in an \fB .xvg\fR file.
-
-
-\&The program \fB trjcat\fR is better suited for concatenating multiple trajectory files.
-\&
-
-
-\&Currently seven formats are supported for input and output:
-\&\fB .xtc\fR, \fB .trr\fR, \fB .trj\fR, \fB .gro\fR, \fB .g96\fR,
-\&\fB .pdb\fR and \fB .g87\fR.
-\&The file formats are detected from the file extension.
-\&The precision of \fB .xtc\fR and \fB .gro\fR output is taken from the
-\&input file for \fB .xtc\fR, \fB .gro\fR and \fB .pdb\fR,
-\&and from the \fB \-ndec\fR option for other input formats. The precision
-\&is always taken from \fB \-ndec\fR, when this option is set.
-\&All other formats have fixed precision. \fB .trr\fR and \fB .trj\fR
-\&output can be single or double precision, depending on the precision
-\&of the \fB trjconv\fR binary.
-\&Note that velocities are only supported in
-\&\fB .trr\fR, \fB .trj\fR, \fB .gro\fR and \fB .g96\fR files.
-
-
-\&Option \fB \-app\fR can be used to
-\&append output to an existing trajectory file.
-\&No checks are performed to ensure integrity
-\&of the resulting combined trajectory file.
-
-
-\&Option \fB \-sep\fR can be used to write every frame to a separate
-\&\fB .gro, .g96\fR or \fB .pdb\fR file. By default, all frames all written to one file.
-\&\fB .pdb\fR files with all frames concatenated can be viewed with
-\&\fB rasmol \-nmrpdb\fR.
-
-
-\&It is possible to select part of your trajectory and write it out
-\&to a new trajectory file in order to save disk space, e.g. for leaving
-\&out the water from a trajectory of a protein in water.
-\&\fB ALWAYS\fR put the original trajectory on tape!
-\&We recommend to use the portable \fB .xtc\fR format for your analysis
-\&to save disk space and to have portable files.
-
-
-\&There are two options for fitting the trajectory to a reference
-\&either for essential dynamics analysis, etc.
-\&The first option is just plain fitting to a reference structure
-\&in the structure file. The second option is a progressive fit
-\&in which the first timeframe is fitted to the reference structure
-\&in the structure file to obtain and each subsequent timeframe is
-\&fitted to the previously fitted structure. This way a continuous
-\&trajectory is generated, which might not be the case when using the
-\®ular fit method, e.g. when your protein undergoes large
-\&conformational transitions.
-
-
-\&Option \fB \-pbc\fR sets the type of periodic boundary condition
-\&treatment:
-
-\&\fB * mol\fR puts the center of mass of molecules in the box.
-
-\&\fB * res\fR puts the center of mass of residues in the box.
-
-\&\fB * atom\fR puts all the atoms in the box.
-
-\&\fB * nojump\fR checks if atoms jump across the box and then puts
-\&them back. This has the effect that all molecules
-\&will remain whole (provided they were whole in the initial
-\&conformation). \fB Note\fR that this ensures a continuous trajectory but
-\&molecules may diffuse out of the box. The starting configuration
-\&for this procedure is taken from the structure file, if one is
-\&supplied, otherwise it is the first frame.
-
-\&\fB * cluster\fR clusters all the atoms in the selected index
-\&such that they are all closest to the center of mass of the cluster,
-\&which is iteratively updated. \fB Note\fR that this will only give meaningful
-\&results if you in fact have a cluster. Luckily that can be checked
-\&afterwards using a trajectory viewer. Note also that if your molecules
-\&are broken this will not work either.
-
-\&The separate option \fB \-clustercenter\fR can be used to specify an
-\&approximate center for the cluster. This is useful e.g. if you have
-\&two big vesicles, and you want to maintain their relative positions.
-
-\&\fB * whole\fR only makes broken molecules whole.
-
-
-\&Option \fB \-ur\fR sets the unit cell representation for options
-\&\fB mol\fR, \fB res\fR and \fB atom\fR of \fB \-pbc\fR.
-\&All three options give different results for triclinic boxes and
-\&identical results for rectangular boxes.
-\&\fB rect\fR is the ordinary brick shape.
-\&\fB tric\fR is the triclinic unit cell.
-\&\fB compact\fR puts all atoms at the closest distance from the center
-\&of the box. This can be useful for visualizing e.g. truncated
-\&octahedra. The center for options \fB tric\fR and \fB compact\fR
-\&is \fB tric\fR (see below), unless the option \fB \-boxcenter\fR
-\&is set differently.
-
-
-\&Option \fB \-center\fR centers the system in the box. The user can
-\&select the group which is used to determine the geometrical center.
-\&Option \fB \-boxcenter\fR sets the location of the center of the box
-\&for options \fB \-pbc\fR and \fB \-center\fR. The center options are:
-\&\fB tric\fR: half of the sum of the box vectors,
-\&\fB rect\fR: half of the box diagonal,
-\&\fB zero\fR: zero.
-\&Use option \fB \-pbc mol\fR in addition to \fB \-center\fR when you
-\&want all molecules in the box after the centering.
-
-
-\&With \fB \-dt\fR, it is possible to reduce the number of
-\&frames in the output. This option relies on the accuracy of the times
-\&in your input trajectory, so if these are inaccurate use the
-\&\fB \-timestep\fR option to modify the time (this can be done
-\&simultaneously). For making smooth movies, the program \fB g_filter\fR
-\&can reduce the number of frames while using low\-pass frequency
-\&filtering, this reduces aliasing of high frequency motions.
-
-
-\&Using \fB \-trunc\fR \fB trjconv\fR can truncate \fB .trj\fR in place, i.e.
-\&without copying the file. This is useful when a run has crashed
-\&during disk I/O (i.e. full disk), or when two contiguous
-\&trajectories must be concatenated without having double frames.
-
-
-\&Option \fB \-dump\fR can be used to extract a frame at or near
-\&one specific time from your trajectory.
-
-
-\&Option \fB \-drop\fR reads an \fB .xvg\fR file with times and values.
-\&When options \fB \-dropunder\fR and/or \fB \-dropover\fR are set,
-\&frames with a value below and above the value of the respective options
-\&will not be written.

-.SH DESCRIPTION
-\&\fB trjorder\fR orders molecules according to the smallest distance
-\&to atoms in a reference group
-\&or on z\-coordinate (with option \fB \-z\fR).
-\&With distance ordering, it will ask for a group of reference
-\&atoms and a group of molecules. For each frame of the trajectory
-\&the selected molecules will be reordered according to the shortest
-\&distance between atom number \fB \-da\fR in the molecule and all the
-\&atoms in the reference group. The center of mass of the molecules can
-\&be used instead of a reference atom by setting \fB \-da\fR to 0.
-\&All atoms in the trajectory are written
-\&to the output trajectory.
-
-
-\&\fB trjorder\fR can be useful for e.g. analyzing the n waters closest to a
-\&protein.
-\&In that case the reference group would be the protein and the group
-\&of molecules would consist of all the water atoms. When an index group
-\&of the first n waters is made, the ordered trajectory can be used
-\&with any Gromacs program to analyze the n closest waters.
-\&
-
-
-\&If the output file is a \fB .pdb\fR file, the distance to the reference target
-\&will be stored in the B\-factor field in order to color with e.g. Rasmol.
-\&
-
-
-\&With option \fB \-nshell\fR the number of molecules within a shell
-\&of radius \fB \-r\fR around the reference group are printed.

-.SH DESCRIPTION
-\&\fB xpm2ps\fR makes a beautiful color plot of an XPixelMap file.
-\&Labels and axis can be displayed, when they are supplied
-\&in the correct matrix format.
-\&Matrix data may be generated by programs such as \fB do_dssp\fR, \fB g_rms\fR or
-\&\fB g_mdmat\fR.
-
-
-\&Parameters are set in the \fB .m2p\fR file optionally supplied with
-\&\fB \-di\fR. Reasonable defaults are provided. Settings for the \fI y\fR\-axis
-\&default to those for the \fI x\fR\-axis. Font names have a defaulting hierarchy:
-\&titlefont \- legendfont; titlefont \- (xfont \- yfont \- ytickfont)
-\&\- xtickfont, e.g. setting titlefont sets all fonts, setting xfont
-\&sets yfont, ytickfont and xtickfont.
-
-
-\&When no \fB .m2p\fR file is supplied, many settings are taken from
-\&command line options. The most important option is \fB \-size\fR,
-\&which sets the size of the whole matrix in postscript units.
-\&This option can be overridden with the \fB \-bx\fR and \fB \-by\fR
-\&options (and the corresponding parameters in the \fB .m2p\fR file),
-\&which set the size of a single matrix element.
-
-
-\&With \fB \-f2\fR a second matrix file can be supplied. Both matrix
-\&files will be read simultaneously and the upper left half of the
-\&first one (\fB \-f\fR) is plotted together with the lower right
-\&half of the second one (\fB \-f2\fR). The diagonal will contain
-\&values from the matrix file selected with \fB \-diag\fR.
-\&Plotting of the diagonal values can be suppressed altogether by
-\&setting \fB \-diag\fR to \fB none\fR.
-\&In this case, a new color map will be generated with
-\&a red gradient for negative numbers and a blue for positive.
-\&If the color coding and legend labels of both matrices are identical,
-\&only one legend will be displayed, else two separate legends are
-\&displayed.
-\&With \fB \-combine\fR, an alternative operation can be selected
-\&to combine the matrices. The output range is automatically set
-\&to the actual range of the combined matrix. This can be overridden
-\&with \fB \-cmin\fR and \fB \-cmax\fR.
-
-
-\&\fB \-title\fR can be set to \fB none\fR to suppress the title, or to
-\&\fB ylabel\fR to show the title in the Y\-label position (alongside
-\&the \fI y\fR\-axis).
-
-
-\&With the \fB \-rainbow\fR option, dull grayscale matrices can be turned
-\&into attractive color pictures.
-
-
-\&Merged or rainbowed matrices can be written to an XPixelMap file with
-\&the \fB \-xpm\fR option.
