.SH DESCRIPTION
-do_dssp
-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. do_dssp assumes that the dssp executable is
-/usr/local/bin/dssp. If this is not the case, then you should
-set an environment variable
-.B DSSP
-pointing to the dssp
-executable, e.g.:

+\&The structure assignment for each residue and time is written to an

+\&The number of residues with each secondary structure type and the

+\&and free energy estimates are analysed, and for each cluster the
+\&energy statistics are printed.
+
+
+\&An alternative approach to this is to cluster the structures first

.SH DESCRIPTION
-g_analyze reads an ascii file and analyzes data sets.
-A line in the input file may start with a time
-(see option
-.B -time
-) and any number of y values may follow.
-Multiple sets can also be
-read when they are seperated by & (option
-.B -n
-),
-in this case only one y 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
-.B -d
-).
-
-
-All options, except for
-.B -av
-and
-.B -power
-assume that the
-points are equidistant in time.
-
-
-g_analyze always shows the average and standard deviation of each
-set. For each set it also shows the relative deviation of the third
-and forth cumulant from those of a Gaussian distribution with the same
-standard deviation.
-
-
-Option
-.B -ac
-produces the autocorrelation function(s).
-
-
-Option
-.B -cc
-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
-.B -msd
-produces the mean square displacement(s).
-
-
-Option
-.B -dist
-produces distribution plot(s).
-
-
-Option
-.B -av
-produces the average over the sets.
-Error bars can be added with the option
-.B -errbar
-.
-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
-.B -ee
-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 sqrt(2/T ( a (tau1 ((exp(-t/tau1) - 1) tau1/t + 1)) +
-
- (1-a) (tau2 ((exp(-t/tau2) - 1) tau2/t + 1)))),
+\&g_analyze 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 y values may follow.
+\&Multiple sets can also be

+
+
+\&Option \fB \-cc\fR plots the resemblance of set i with a cosine of

+
+\&This is useful for principal components obtained from covariance

+
+
+\&Option \fB \-av\fR produces the average over the sets.

+\&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 sqrt(2/T ( a (tau1 ((exp(\-t/tau1) \- 1) tau1/t + 1)) +
+
+\& (1\-a) (tau2 ((exp(\-t/tau2) \- 1) tau2/t + 1)))),
where T is the total time.
-a, 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*sqrt(2/T (a tau1 + (1-a) tau2)).

+\&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

+.SH DESCRIPTION
+\&g_bar calculates free energy difference estimates through
+\&Bennett's acceptance ratio method.
+\&Input option \fB \-f\fR expects multiple dhdl files.
+\&Two types of input files are supported:
+
+\&* Files with only one y\-value, for such files it is assumed
+\&that the y\-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.
+\&
+
+\&* Files with more than one y\-value. The files should have columns
+\&with dH/dlambda and Delta lambda. The lambda values are inferred
+\&from the legends:
+\&lambda of the simulation from the legend of dH/dlambda
+\&and the foreign lambda's from the legends of Delta H.
+
+
+\&The lambda of the simulation is parsed from dhdl.xvg file's legend
+\&containing the string 'dH', the foreign lambda's from the legend
+\&containing the capitalized letters 'D' and 'H'. The temperature
+\&is parsed from the legend line containing 'T ='.
+
+
+\&The free energy estimates are determined using BAR with bisection,
+\&the precision of the output is 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 blocks numbers for error estimation can
+\&be provided with the options \fB \-nbmin\fR and \fB \-nbmax\fR.
+
+
+\&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:
+
+\&* lam_A: the lambda values for point A.
+
+\&* lam_B: the lambda values for point B.
+
+\&* DG: the free energy estimate.
+
+\&* s_A: an estimate of the relative entropy of B in A.
+
+\&* s_A: an estimate of the relative entropy of A in B.
+
+\&* 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 (2009) 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 gives an estimate
+\&of the quality of sampling (not directly of the actual statistical
+\&error, because it assumes independent samples).

.SH DESCRIPTION
-g_chi 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 (histo-(dihedral)(RESIDUE).xvg) are cumulative over all residues of each type.
-
-
-If option
-.B -corr
-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),
-.B Biophys. J. 72

+\&This program computes the size distributions of molecular/atomic clusters in
+\&the gas phase. The output is given in the form of a XPM file.
+\&The total number of clusters is written to a XVG file.
-When the
-.B -mol
-option is given clusters will be made out of
-molecules rather than atoms, which allows clustering of large molecules.
-In this case an index file would still contain atom numbers
-or your calculcation will die with a SEGV.

+\&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 xvg 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 -ndf option. Remember to take the removal
-of center of mass motion into account.

.SH DESCRIPTION
-This 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 also
-allows to get the static conductivity.
-
-
-The flag
-.B -caf
-is for the output of the current autocorrelation function and
-.B -mc
-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
-.B -sh
-and
-.B -tr
-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
-.B -sh
-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
-.B -tr
-controls the region of the integral taken into account
-for calculating the static dielectric constant.
-
-
-
-Option
-.B -temp
-sets the temperature required for the computation of the static dielectric constant.
-
-
-Option
-.B -eps
-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).
-
-
-
-
-.B -[no]nojump
-unfolds the coordinates to allow free diffusion. This is required to get a continuous
-translational dipole moment, required for the Einstein-Helfand fit. The resuls from the fit allow to
-determine 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
-options 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.

-file can be visualized with for instance xv
-and can be converted to postscript with xpm2ps.
-
-
-
-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
-.B -aver
-.
-When
-.B -xmin
-and/or
-.B -xmax
-are set only atoms that are

-The grid spacing is set with the option
-.B -bin
-.
-When
-.B -n1
-or
-.B -n2
-is non-zero, the grid
-size is set by this option.
-Box size fluctuations are properly taken into account.
-
-
-
-When options
-.B -amax
-and
-.B -rmax
-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
-.B -mirror
-option has been set.
-
-
-
-The normalization of the output is set with the
-.B -unit
-option.
-The default produces a true number density. Unit
-.B nm-2
-leaves out
-the normalization for the averaging or the angular direction.
-Option

.SH DESCRIPTION
-dielectric calculates frequency dependent dielectric constants
-from the autocorrelation function of the total dipole moment in
-your simulation. This ACF can be generated by g_dipoles.
-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 parmeter : y = Exp[-a1 x]
-Two parmeters : y = a2 Exp[-a1 x]
-Three parmeter: y = a2 Exp[-a1 x] + (1 - a2) Exp[-a3 x]
-Startvalues for the fit procedure can be given on the commandline.
-It is also possible to fix parameters at their start value, use -fix
-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

-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

-Because of limited numerical accuracy this should be verified by

-The purpose of this program is to interpolate and extrapolate the

.SH DESCRIPTION
-g_enemat extracts an energy matrix from the energy file (
-.B -f
-).
-With
-.B -groups
-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
-.B -groups
-file contains:
-
-
-.B 2
-
-
-
-.B Protein
-
-
-
-.B SOL
-
-
-then energy groups with names like 'Coul-SR:Protein-SOL' and
-'LJ:Protein-SOL' are expected in the energy file (although
-
-.B g_enemat
-is most useful if many groups are analyzed
-simultaneously). Matrices for different energy types are written
-out separately, as controlled by the

.SH DESCRIPTION
-g_energy extracts energy components or distance restraint
-data from an energy file. The user is prompted to interactively
-select the energy terms she wants.
-
-
-Average and RMSD are calculated with full precision from the
-simulation (see printed manual). Drift is calculated by performing
-a LSQ fit of the data to a straight line. Total drift is drift
-multiplied by total time. The term fluctuation gives the RMSD around
-the LSQ fit.
-
-
-When the
-.B -viol
-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
-.B -pairs
-option.
-
-
-Options
-.B -ora
-,
-.B -ort
-,
-.B -oda
-,
-.B -odr
-and
-
-.B -odt
-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
-.B -odr
-plots the RMS
-deviation as a function of restraint.
-When the run used time or ensemble averaged orientation restraints,
-option
-.B -orinst
-can be used to analyse the instantaneous,
-not ensemble-averaged orientations and deviations instead of
-the time and ensemble averages.
-
-
-Option
-.B -oten
-plots the eigenvalues of the molecular order
-tensor for each orientation restraint experiment. With option
-
-.B -ovec
-also the eigenvectors are plotted.
-
-
-With
-.B -fee
-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
-.B -fetemp
-andthe 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 (
-.B -f2
-), 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.
-.B NOTE
-that
-the energies must both be calculated from the same trajectory.
+\&g_energy extracts energy components or distance restraint
+\&data from an energy file. The user is prompted to interactively
+\&select the energy terms she wants.
+
+
+\&Average, RMSD and drift are calculated with full precision from the
+\&simulation (see printed manual). Drift is calculated by performing
+\&a LSQ 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.
+\&Note 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 g_energy statistics output more accurate
+\&than the xvg output. When exact averages are not present in the energy
+\&file the statistics mentioned above is simply over the single, per\-frame
+\&energy values.
+
+
+\&The term fluctuation gives the RMSD around the LSQ fit.
+
+
+\&Some fluctuation\-dependent properties can be calculated provided
+\&the correct energy terms are selected. The following properties

.SH DESCRIPTION
-g_filter 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
-.B -nf
-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
-.B -ol
-writes a low-pass filtered trajectory.
-A frame is written every
-.B nf
-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
-.B -all
-option.
-
-
-Option
-.B -oh
-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
-.B -fit
-
-or make sure you use a trajectory which has been fitted on

+.SH DESCRIPTION
+\&g_membed 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. Box size should be taken from the membrane structure file. The corresponding topology
+\&files should also be merged. Consecutively, create a tpr file (input for g_membed) from these files,with the following options included in the mdp file.
+
+\& \- integrator = md
+
+\& \- energygrp = Protein (or other group that you want to insert)
+
+\& \- freezegrps = Protein
+
+\& \- freezedim = Y Y Y
+
+\& \- energygrp_excl = Protein Protein
+
+\&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 \-xy in the xy\-plane
+\&(the membrane plane) and a factor \-z in the z\-direction (if the size of the
+\&protein in the z\-direction is the same or smaller than the width of the membrane, a
+\&\-z 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 \-xy
+\& or \-z
+
+\&3. One md step is performed.
+
+\&4. The resize factor (\-xy or \-z) 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 \-xy factor
+\&is 1 (thus after \-nxy iteration).
+
+\&5. Repeat step 3 and 4 until the protein reaches its original size (\-nxy + \-nz iterations).
+
+\&For a more extensive method descrition 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.

-g_msd computes the mean square displacement (MSD) of atoms from

-the diffusion constant using the Einstein relation.
-The time between additional starting points for the MSD calculation
-is set with
-.B -trestart
-.
-The diffusion constant is calculated by least squares fitting a
-straight line through the MSD from
-.B -beginfit
-to
-
-.B -endfit
-. An error estimate given, which is the difference
-of the diffusion coefficients obtained from fits over the two halfs
-of the fit interval.
-
-
-There are three, mutually exclusive, options to determine different
-types of mean square displacement:
-.B -type
-,
-.B -lateral
-
-and
-.B -ten
-. Option
-.B -ten
-writes the full MSD tensor for

-
-
-Option
-.B -mol
-plots the MSD for molecules, this implies
-With option
-.B -rmcomm
-center of mass motion can be removed.
-For trajectories produced with GROMACS this is usually not necessary

-When you use this option be sure that the whole system is stored

-
-
-
-.B -mw
-, i.e. for each inidividual molecule an diffusion constant
-is computed for its center of mass. The chosen index group will
-be split into molecules.
-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 restart point, i.e. short times have
-a higher weight. Also when
-.B -beginfit
-=-1,fitting starts at 0
-and when
-.B -endfit
-=-1, fitting goes to the end.
-Using this option one also gets an accurate error estimate

+\&g_msd 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

+
+
+\&There are three, mutually exclusive, options to determine different

+\&and \fB \-ten\fR. Option \fB \-ten\fR writes the full MSD tensor for

+
+
+\&If \fB \-mol\fR is set, g_msd plots the MSD for individual molecules:
+\&for each individual molecule a diffusion constant is computed for

+
+
+\&The default way to calculate a MSD is by using mass\-weighted averages.
+\&This can be turned off with \fB \-nomw\fR.

+
+\&The diffusion coefficient is determined by linear regression of the MSD,
+\&where, unlike for the normal output of D, the times are weighted

-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 unrealistic 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

-Compute the order parameter per atom for carbon tails. For atom i the

-a group with all equivalent atoms in all tails for each atom the
-order parameter has to be calculated for. The program can also give all
-diagonal elements of the order tensor and even calculate the deuterium
-order parameter Scd (default). If the option -szonly is given, only one
-order tensor component (specified by the -d option) is given and the
-order parameter per slice is calculated as well. If -szonly is not
-selected, all diagonal elements and the deuterium order parameter is
-given.
+\&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

+\&order parameter per slice is calculated as well. If \-szonly is not
+\&selected, all diagonal elements and the deuterium order parameter is
+\&given.
The tetrahedrality order parameters can be determined

-g_polystat plots static properties of polymers as a function of time

-
-
-By default it determines the average end-to-end distance and radii
-of gyration of polymers. It asks for an index group and split this
-into molecules. The end-to-end distance is then determined using
-the first and the last atom in the index group for each molecules.
-For the radius of gyration the total and the three principal components
-for the average gyration tensor are written.
-With option
-.B -v
-the eigenvectors are written.
-With option
-.B -pc
-also the average eigenvalues of the individual
-gyration tensors are written.
-
-
-With option
-.B -p
-the presistence length is determined.
-The chosen index group should consist of atoms that are
-consecutively bonded in the polymer mainchains.
-The presistence 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).

-The structure of liquids can be studied by either neutron or X-ray

-a scattering experiment.
-
-
-g_rdf calculates radial distribution functions in different ways.
-The normal method is around a (set of) particle(s), the other method
-is around the center of mass of a set of particles.
-With both methods rdf's can also be calculated around axes parallel

.SH DESCRIPTION
-g_rms compares two structures by computing the root mean square
-deviation (RMSD), the size-independent 'rho' similarity parameter
-(rho) or the scaled rho (rhosc),
-see Maiorov & Crippen, PROTEINS
-.B 22
-, 273 (1995).
-This is selected by
-.B -what
-.
-
-Each structure from a trajectory (
-.B -f
-) is compared to a
-reference structure. The reference structure
-is taken from the structure file (
-.B -s
-).
-
-
-With option
-.B -mir
-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
-.B 22
-, 273 (1995).
-
-
-Option
-.B -prev
-produces the comparison with a previous frame
-the specified number of frames ago.
-
-
-Option
-.B -m
-produces a matrix in
-.B .xpm
-format of
-comparison values of each structure in the trajectory with respect to
-each other structure. This file can be visualized with for instance
-
-.B xv
-and can be converted to postscript with
-.B xpm2ps
-.
-
-
-Option
-.B -fit
-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
-.B -mw
-controls whether mass weighting is done or not.
-If you select the option (default) and
-supply a valid tpr file masses will be taken from there,
-otherwise the masses will be deduced from the atommass.dat file in
-the GROMACS library directory. 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
-.B -debug
-flag and inspecting the log file.
-
-
-With
-.B -f2
-, the 'other structures' are taken from a second
-trajectory, this generates a comparison matrix of one trajectory
-versus the other.
-
-
-Option
-.B -bin
-does a binary dump of the comparison matrix.
-
-
-Option
-.B -bm
-produces a matrix of average bond angle deviations
-analogously to the

.SH DESCRIPTION
-g_rotacf 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 -d switch, you can
-calculate the rotational correlation function for linear molecules
-by specifying two atoms (i,j) in the index file.

+.SH DESCRIPTION
+\&g_rotmat 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 xy\-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 x/y plane can
+\&be performed.
+\&
+
+
+\&Option \fB \-fitxy\fR fits in the x/y plane before determining
+\&the rotation matrix.

-The program will ask for a group for the surface calculation

-The output group can be the whole or part of the calculation group.
-The area can be plotted

-).
-In combination with the latter option an

.SH DESCRIPTION
-g_sdf calculates the spatial distribution function (SDF) of a set of atoms
-within a coordinate system defined by three atoms. There is single body,
-two body and three body SDF implemented (select with option -mode).
-In the single body case the local coordinate system is defined by using
-a triple of atoms from one single molecule, for the two and three body case
-the configurations are dynamically searched complexes of two or three
-molecules (or residues) meeting certain distance consitions (see below).

-The programm will dynamically generate the atom tripels according to

-In -mode 1 the triples will be just the 1st, 2nd, 3rd, ... atoms from
-groups 1, 2 and 3. Hence the nth entries in groups 1, 2 and 3 must be from the
-same residue. In -mode 2 the triples will be 1st, 2nd, 3rd, ... atoms from
-groups 1 and 2 (with the nth entries in groups 1 and 2 having the same res-id).
-For each pair from groups 1 and 2 group 3 is searched for an atom meeting the
-distance conditions set with -triangle and -dtri relative to atoms 1 and 2. In
--mode 3 for each atom in group 1 group 2 is searched for an atom meeting the
-distance condition and if a pair is found group 3 is searched for an atom
-meeting the further conditions. The triple will only be used if all three atoms
-have different res-id's.

-The local coordinate system is always defined using the following scheme:
-Atom 1 will be used as the point of origin for the SDF. Atom 1 and 2 will define the principle axis (Z) of the coordinate system.
-The other two axis will be defined inplane (Y) and normal (X) to the plane through
-Atoms 1, 2 and 3. The fourth group

+.SH DESCRIPTION
+\&g_select 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 make_ndx 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
-g_sham makes multi-dimensional free-energy, enthalpy and entropy plots.
-g_sham reads one or more xvg files and analyzes data sets.
-g_sham basic purpose is plotting Gibbs free energy landscapes
-(option
-.B -ls
-)
-by Bolzmann inverting multi-dimensional histograms (option
-.B -lp
-)
-but it can also
-make enthalpy (option
-.B -lsh
-) and entropy (option
-.B -lss
-)
-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
-.B -time
-) and any number of y values may follow.
-Multiple sets can also be
-read when they are seperated by & (option
-.B -n
-),
-in this case only one y value is read from each line.
-All lines starting with and @ are skipped.
-
-
-
-Option
-.B -ge
-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
-.B -f
-input.
-
-
-
-Option
-.B -ene
-can be used to supply a file with energies.
-These energies are used as a weighting function in the single
-histogram analysis method due to Kumar et. al. When also 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
-.B -dim
-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 a dimension 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.
-Note 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.

-RMS deviation after fitting or RMS deviation of atom-pair distances
-can be used to define the distance between structures.
+\&g_spatial 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 32K atoms and a 50ns trajectory, the SDF can be generated
+\&in about 30 minutes, with most of the time dedicated to the two runs through
+\&trjconv that are required to center everything properly.
+\&This also takes a whole bunch of space (3 copies of the xtc 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 arbitrarty
+\&Cartesian coordinate. To do that, simply omit the preliminary trjconv steps.
+\&USAGE:
-single linkage: add a structure to a cluster when its distance to any
-element of the cluster is less than
-.B cutoff
-.
+\&1. Use make_ndx to create a group containing the atoms around which you want the SDF
+\&2. trjconv \-s a.tpr \-f a.xtc \-o b.xtc \-center tric \-ur compact \-pbc none
-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
-.B P
-neighbors in common. The neighbors
-of a structure are the M closest structures or all structures within
+\&3. trjconv \-s a.tpr \-f b.xtc \-o c.xtc \-fit rot+trans
-.B cutoff
-.
+\&4. run g_spatial on the xtc output of step 3.
+\&5. Load grid.cube into VMD and view as an isosurface.
-Monte Carlo: reorder the RMSD matrix using Monte Carlo.
+\&*** Systems such as micelles will require trjconv \-pbc cluster between steps 1 and 2
+\&WARNINGS:
-diagonalization: diagonalize the RMSD matrix.
+\&The SDF will be generated for a cube that contains all bins that have some non\-zero occupancy.
+\&However, the preparatory \-fit rot+trans option to trjconv 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.
-gromos: use algorithm as described in Daura
-.I et al.
+\&BUGS:
-(
-.I Angew. Chem. Int. Ed.
+\&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 \-nab
+\&option. However, the program does not detect all such events. If you encounter a segmentation fault, run it again
+\&with an increased \-nab value.

-, pp 236-240).
-Count number of neighbors using cut-off, take structure with
-largest number of neighbors with all its neighbors as cluster
-and eleminate it from the pool of clusters. Repeat for remaining
-structures in pool.
+\&RISKY OPTIONS:
-
-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:
-
-
-.B -o
-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
-.B -minstruct
-= 1 the graphical depiction is black
-when two structures are in the same cluster.
-When
-.B -minstruct
- 1 different colors will be used for each
-cluster.
-
-
-.B -g
-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:
-
-
-.B -dist
-writes the RMSD distribution.
-
-
-.B -ev
-writes the eigenvectors of the RMSD matrix
-diagonalization.
-
-
-.B -sz
-writes the cluster sizes.
-
-
-.B -tr
-writes a matrix of the number transitions between
-cluster pairs.
-
-
-.B -ntr
-writes the total number of transitions to or from
-each cluster.
-
-
-.B -clid
-writes the cluster number as a function of time.
-
-
-.B -cl
-writes average (with option
-.B -av
-) or central
-structure of each cluster or writes numbered files with cluster members
-for a selected set of clusters (with option
-.B -wcl
-, depends on
-
-.B -nst
-and
-.B -rmsmin
-).
+\&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 trjconv.
+\&However, be sure to set the \-nab option to a sufficiently high value since
+\&memory is allocated for cube bins based on the initial coords and the \-nab
+\&(Number of Additional Bins) option value.

.SH DESCRIPTION
-g_tcaf computes tranverse current autocorrelations.
-These are used to estimate the shear viscosity eta.
-For details see: Palmer, JCP 49 (1994) pp 359-366.
-
-
-Transverse currents are calculated using the
-k-vectors (1,0,0) and (2,0,0) each also in the y- and z-direction,
-(1,1,0) and (1,-1,0) each also in the 2 other plains (these vectors
-are not independent) and (1,1,1) and the 3 other box diagonals (also
-not 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 tau's
-and eta's. The fit weights decay with time as exp(-t/wt), the tcaf and
-fit are calculated up to time 5*wt.
-The eta's 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
-.B -oc
-, 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
-.B -oc
-
-The cubic eta estimates are also written to
-.B -ov
-.
-
-
-With option
-.B -mol
-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
-.B -ov
-file should be
-fitted to eta(k) = eta0 (1 - a k2) to obtain the viscosity at
-infinite wavelength.
-
-
-NOTE: 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
+\&For a given number \fB \-np\fR or \fB \-nt\fR of processors/threads, this program systematically
+\× mdrun 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 g_tune_pme together with other options
+\&for mdrun 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.
+\&'export MPIRUN="/usr/local/mpirun \-machinefile hosts"'
+
+
+\&Please call g_tune_pme with the normal options you would pass to
+\&mdrun 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.
+
+
+\&g_tune_pme 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 (no. 0) will be with the settings from the input
+\&\fB .tpr\fR file; the last test (no. \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 equally
+\&spaced values inbetween these extremes. Note 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 mdrun several times, detailed performance information
+\&is available in the output file perf.out.
+\&Note that during the benchmarks a couple of temporary files are written
+\&(options \-b*), 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
-g_vanhove 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.
-g_vanhove 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
-.B -om
-the whole matrix can be written as a function
-of t and r or as a function of sqrt(t) and r (option
-.B -sqrt
-).
-
-
-
-With option
-.B -or
-the Van Hove function is plotted for one
-or more values of t. Option
-.B -nr
-sets the number of times,
-option
-.B -fr
-the number spacing between the times.
-The binwidth is set with option
-.B -rbin
-. The number of bins
-is determined automatically.
-
-
-
-With option
-.B -ot
-the integral up to a certain distance
-(option
-.B -rt
-) 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
-.B -om
-and
-.B -ot
-the program may be slow.
-This is because the calculation scales as the number of frames times
-
-.B -fm
-or
-.B -ft
-.
-Note that with the
-.B -dt
-option the memory usage and calculation
-time can be reduced.

+
+\&\fB \-histbs\fR Complete histograms are considered as independent data points (default). For each
+\&bootstrap, N histograms are randomly chosen from the N given histograms (allowing duplication).
+\&To avoid gaps without data along the reaction coordinate blocks of histograms (\-histbs\-block)
+\&may be defined. In that case, the given histograms are divided 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 undererstimated!
+
+\&\fB \-nohistbs\fR The given histograms are used to generate new random histograms,
+\&such that the generated data points are distributed according the given histograms. The number
+\&of points generated for each bootstrap histogram can be controlled with \-bs\-dt.
+\&Note that one data point should be generated for each *independent* point in the given
+\&histograms. With the long autocorrelations in MD simulations, this procedure may
+\&easily understimate the error!
+
+\&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,

+.SH DESCRIPTION
+\&x2top 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 rtp entry, which you can then add
+\&to the rtp 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 atomname2type.n2t. Check chapter 5 of the manual for more
+\&information about file formats. By default the forcefield selection
+\&is interactive, but you can use the \fB \-ff\fR option to specify

.SH DESCRIPTION
-Genbox can do one of 3 things:
-
-
-1) Generate a box of solvent. Specify -cs and -box. Or specify -cs and
--cp with a structure file with a box, but without atoms.
-
-
-2) Solvate a solute configuration, eg. a protein, in a bath of solvent
-molecules. Specify
-.B -cp
-(solute) and
-.B -cs
-(solvent).
-The box specified in the solute coordinate file (
-.B -cp
-) is used,
-unless
-.B -box
-is set.
-If you want the solute to be centered in the box,
-the program
-.B editconf
-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 VanderWaals radii of
-both atoms. A database (
-.B vdwradii.dat
-) of VanderWaals radii is
-read by the program, atoms not in the database are
-assigned a default distance
-.B -vdw
-.
-
-
-3) Insert a number (
-.B -nmol
-) of extra molecules (
-.B -ci
-)
-at random positions.
-The program iterates until
-.B nmol
-molecules
-have been inserted in the box. To test whether an insertion is
-successful the same VanderWaals 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
-.B -nmol
-*
-.B -try
-times before giving up.
-Increase -try if you have several small holes to fill.
-
-
-The default solvent is Simple Point Charge water (SPC), with coordinates
-from
-.B $GMXLIB/spc216.gro
-. 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 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 eg. 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 -shell 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 editconf).
-
-
-
-Finally, genbox 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
-genion 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
-.B -table
-.
-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 and include
-the file
-.B ions.itp
-.
-Ion names for Gromos96 should include the charge.
-
-
-With the option
-.B -pot
-the potential can be written as B-factors
-in a pdb file (for visualisation using e.g. rasmol).
-The unit of the potential is 1000 kJ/(mol e), the scaling be changed
-with the
-.B -scale
-option.
-
-
-For larger ions, e.g. sulfate we recommended to use genbox.

-and prints out useful information about them.
-
-
-Option
-.B -c
-checks for presence of coordinates,
-velocities and box in the file, for close contacts (smaller than
-
-.B -vdwfac
-and not bonded, i.e. not between
-.B -bonlo
-
-and
-.B -bonhi
-, all relative to the sum of both Van der Waals

-will be calculated from them.
-
-
-If an index file is given it's contents will be sumamrized.
-
-
-If both a trajectory and a tpr file are given (with
-.B -s1
-)
-the program will check whether the bond lengths defined in the tpr
-file are indeed correct in the trajectory. If not you may have
-non-matching files due to e.g. deshuffling or due to problems with
-virtual sites. With these flags, gmxcheck provides a quick check for such problems.

-) files
-when both

-are supplied.
-Similarly a pair of trajectory files can be compared (using the

.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.
-grompp also reads parameters for the mdrun
-(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.
-
-
-grompp uses the atom names from the topology file. The atom names
-in the coordinate file (option
-.B -c
-) 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.
-
-
-grompp calls a preprocessor to resolve includes, macros
-etcetera. By default we use the cpp in your path. To specify a different macro-preprocessor (e.g. m4) or alternative location
-you can put a line in your parameter file specifying the path
-to that program. Specifying
-.B -pp
-will get the pre-processed
-topology file written out.
-
-
-If your system does not have a c-preprocessor, you can still
-use grompp, but you do not have access to the features
-from the cpp. Command line options to the c-preprocessor can be given
-in the
-.B .mdp
-file. See your local manual (man cpp).
-
-
-When using position restraints a file with restraint coordinates
-can be supplied with
-.B -r
-, otherwise restraining will be done
-with respect to the conformation from the
-.B -c
-option.
-For free energy calculation the the coordinates for the B topology
-can be supplied with
-.B -rb
-, otherwise they will be equal to
-those of the A topology.
-
-
-Starting coordinates can be read from trajectory with
-.B -t
-.
-The last frame with coordinates and velocities will be read,
-unless the
-.B -time
-option is used.
-Note that these velocities will not be used when
-.B gen_vel = yes
-
-in your
-.B .mdp
-file. An energy file can be supplied with
-
-.B -e
-to have exact restarts when using pressure and/or
-Nose-Hoover temperature coupling. For an exact restart do not forget
-to turn off velocity generation and turn on unconstrained starting
-when constraints are present in the system.
-If you want to continue a crashed run, it is
-easier to use
-.B tpbconv
-.
-
-
-Using the
-.B -morse
-option grompp can convert the harmonic bonds
-in your topology to morse potentials. This makes it possible to break
-bonds. For this option to work you need an extra file in your $GMXLIB
-with dissociation energy. Use the -debug option to get more information
-on the workings of this option (look for MORSE in the grompp.log file
-using less or something like that).
-
-
-By default all bonded interactions which have constant energy due to
-virtual site constructions will be removed. If this constant energy is
-not zero, this will result in a shift in the total energy. All bonded
-interactions can be kept by turning off
-.B -rmvsbds
-. 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.

+
+
+\&grompp uses a built\-in preprocessor to resolve includes, macros

+
+\&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:
+
+\&define = \-DVARIABLE1 \-DVARIABLE2
+
+\&include = /home/john/doe
+
+\&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.

.SH DESCRIPTION
-The mdrun 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 mdrun
-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 g_nmeig.
-
-
-The mdrun program reads the run input file (
-.B -s
-)
-and distributes the topology over nodes if needed.
-mdrun produces at least four output files.
-A single log file (
-.B -g
-) is written, unless the option
-
-.B -seppot
-is used, in which case each node writes a log file.
-The trajectory file (
-.B -o
-), contains coordinates, velocities and
-optionally forces.
-The structure file (
-.B -c
-) contains the coordinates and
-velocities of the last step.
-The energy file (
-.B -e
-) 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
-(
-.B -x
-).
-
-
-The option
-.B -dgdl
-is only used when free energy perturbation is
-turned on.
-
-
-When mdrun is started using MPI with more than 1 node, parallelization
-is used. By default domain decomposition is used, unless the
-.B -pd
-
-option is set, which selects particle decomposition.
-
-
-With domain decomposition, the spatial decomposition can be set
-with option
-.B -dd
-. By default mdrun 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
-.B -dlb
-,
-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
-.B -npme
-,
-this can not be more than half of the nodes.
-By default mdrun makes a guess for the number of PME
-nodes when the number of nodes is larger than 11 or performance wise
-not 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
-.B -rdd
-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
-.B -rdd
-.
-With dynamic load balancing option
-.B -rdd
-also sets
-the lower limit for the domain decomposition cell sizes.
-By default
-.B -rdd
-is determined by mdrun 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, mdrun 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
-.B -noddcheck
-.
-
-
-When constraints are present, option
-.B -rcon
-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 mdrun 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
-.B -rcon
-.
-
-
-The
-.B -dds
-option sets the minimum allowed x, y and/or z scaling
-of the cells with dynamic load balancing. mdrun 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
-.B -dd
-)
-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
-.B -dds
-might need to be adjusted to account for
-high or low spatial inhomogeneity of the system.
-
-
-
-The option
-.B -nosum
-can be used to only sum the energies
-at every neighbor search step and energy output step.
-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 nstlist steps.
-With this option the energy file will not contain averages and
-fluctuations over all integration steps.
-
-
-With
-.B -rerun
-an input trajectory can be given for which
-forces and energies will be (re)calculated. Neighbor searching will be
-performed for every frame, unless
-.B nstlist
-is zero
-(see the
-.B .mdp
-file).
-
-
-ED (essential dynamics) sampling is switched on by using the
-.B -ei
-
-flag followed by an
-.B .edi
-file.
-The
-.B .edi
-file can be produced using options in the essdyn
-menu of the WHAT IF program. mdrun produces a
-.B .edo
-file that
-contains projections of positions, velocities and forces onto selected
-eigenvectors.
-
-
-When user-defined potential functions have been selected in the
-
-.B .mdp
-file the
-.B -table
-option is used to pass mdrun
-a formatted table with potential functions. The file is read from
-either the current directory or from the GMXLIB directory.
-A number of pre-formatted tables are presented in the GMXLIB 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
-.B -tablep
-option.
-
-
-When tabulated bonded functions are present in the topology,
-interaction functions are read using the
-.B -tableb
-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
-.B -pi
-,
-.B -po
-,
-.B -pd
-,
-.B -pn
-are used
-for potential of mean force calculations and umbrella sampling.
-See manual.
-
-
-With
-.B -multi
-multiple systems are simulated in parallel.
-As many input files are required as the number of systems.
-The system number is appended to the run input and each output filename,
-for instance topol.tpr becomes topol0.tpr, topol1.tpr etc.
-The number of nodes per system is the total number of nodes
-divided 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
-.B -replex
-replica exchange is attempted every given number
-of steps. The number of replicas is set with the
-.B -multi
-option,
-see 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
-
-.B -reseed
-. 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, glass simulations
-and X-Ray bombardments.
-
-
-
-The option
-.B -pforce
-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
-.B -cpt
-) to the file
-.B -cpo
-,
-unless option
-.B -cpt
-is set to -1.
-A simulation can be continued by reading the full state from file
-with option
-.B -cpi
-. 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 tpr file.
-
-
-
-With checkpointing you can also use the option
-.B -append
-to
-just continue writing to the previous output files. This is not
-enabled by default since it is potentially dangerous if you move files,
-but if you just leave all your files in place and restart mdrun with
-exactly the same command (with options
-.B -cpi
-and
-.B -append
-)
-the result will be the same as from a single run. The contents will
-be binary identical (unless you use dynamic load balancing),
-but for technical reasons there might be some extra energy frames when
-using checkpointing (necessary for restarts without appending).
-
-
-
-With option
-.B -maxh
-a simulation is terminated and a checkpoint
-file is written at the first neighbor search step where the run time
-exceeds
-.B -maxh
-*0.99 hours.
-
-
-
-When mdrun receives a TERM signal, it will set nsteps to the current
-step plus one. When mdrun receives a USR1 signal, 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 mdrun processes
-is sufficient, this signal should not be sent to mpirun or
-the mdrun process that is the parent of the others.
-
-
-
-When mdrun is started with MPI, it does not run niced by default.
+\&The mdrun 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 mdrun
+\&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 g_nmeig.
+
+
+\&The mdrun program reads the run input file (\fB \-s\fR)
+\&and distributes the topology over nodes if needed.
+\&mdrun 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 mdrun 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 mdrun 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,

+\&For a global thermostat and/or barostat the temperature

+
+
+\&With \fB \-multi\fR multiple systems are simulated in parallel.

+\&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,

+\&loose data when some output files are modified, corrupt or removed.
+\&There are three scenarios with \fB \-cpi\fR:
+
+\&* no files with matching names are present: new output files are written
+
+\&* all files are present with names and checksums matching those stored
+\&in the checkpoint file: files are appended
+
+\&* 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 mdrun receives a TERM signal, it will set nsteps to the current

.SH DESCRIPTION
-This program reads a pdb file, reads
-some database files, adds hydrogens to the molecules and generates
-coordinates in Gromacs (Gromos) format and a topology in Gromacs format.
-These files can subsequently be processed to generate a run input file.
-
-
-
-The force fields in the distribution are currently:
-
-
-oplsaa OPLS-AA/L all-atom force field (2001 aminoacid dihedrals)
-
-G43b1 GROMOS96 43b1 Vacuum Forcefield
-
-G43a1 GROMOS96 43a1 Forcefield
-
-G43a2 GROMOS96 43a2 Forcefield (improved alkane dihedrals)
-
-G45a3 GROMOS96 45a3 Forcefield
-
-G53a5 GROMOS96 53a5 Forcefield
-
-G53a6 GROMOS96 53a6 Forcefield
-
-gmx Gromacs Forcefield (a modified GROMOS87, see manual)
-
-encads Encad all-atom force field, using scaled-down vacuum charges
-
-encadv Encad all-atom force field, using full solvent charges
-
-
-The corresponding data files can be found in the library directory
-with names like ffXXXX.YYY. Check chapter 5 of the manual for more
-information about file formats. By default the forcefield selection
-is interactive, but you can use the
-.B -ff
-option to specify
-one of the short names above on the command line instead. In that
-case pdb2gmx just looks for the corresponding file.
-
-
-Note that a pdb 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 LYS (two protons on NZ) or LYSH
-(three protons, default), for ASP and GLU unprotonated (default) or
-protonated, for HIS the proton can be either on ND1 (HISA), on NE2
-(HISB) or on both (HISH). 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
-criterium, specified by the maximum hydrogen-donor-acceptor angle
-and donor-acceptor distance, which are set by
-.B -angle
-and
-
-.B -dist
-respectively.
-
-
-Option
-.B -merge
-will ask if you want to merge consecutive chains
-into one molecule definition, this can be useful for connecting chains
-with a disulfide brigde or intermolecular distance restraints.
-
-
-pdb2gmx will also check the occupancy field of the pdb file.
-If any of the occupanccies are not one, indicating that the atom is
-not resolved well in the structure, a warning message is issued.
-When a pdb 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
-.B -n
-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
-.B -ignh
-.
-
-
-The
-.B .gro
-and
-.B .g96
-file formats do not support chain
-identifiers. Therefore it is useful to enter a pdb file name at
-the
-.B -o
-option when you want to convert a multichain pdb file.
-
-
-
-The option
-.B -vsite
-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, elminating the fast improper dihedral
-fluctuations in these rings. Note 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
-.B -heavyh
-
-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.
+\&This program reads a pdb (or gro) file, reads
+\&some database files, adds hydrogens to the molecules and generates
+\&coordinates in Gromacs (Gromos), or optionally pdb, format
+\&and a topology in Gromacs format.
+\&These files can subsequently be processed to generate a run input file.
+\&
+
+
+\&pdb2gmx 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 Gomracs 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 pdb2gmx 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 residuetypes.dat in the libary 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 pdb file is nothing more than a file format, and it
+\&need not necessarily contain a protein structure. Every kind of

+\&\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 molecule_type\fR definition.
+\&To handle this, pdb2gmx 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.
+
+
+\&pdb2gmx will also check the occupancy field of the pdb 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 pdb file does not originate from an X\-Ray structure determination
+\&all occupancy fields may be zero. Either way, it is up to the user

-trjcat concatenates several input trajectory files in sorted order.
-In case of double time frames the one in the later file is used.
-By specifying
-.B -settime
-you will be asked for the start time
-of each file. The input files are taken from the command line,
-such that a command like
-.B trjcat -o fixed.trr *.trr
-should do
-the trick. Using
-.B -cat
-you can simply paste several files
-together without removal of frames with identical time stamps.
-
-
-One important option is inferred when the output file is amongst the
-input files. In that case that particular file will be appended to
-which implies you do not need to store double the amount of data.
-Obviously the file to append to has to be the one with lowest starting
-time since one can only append at the end of a file.
-
-
-If the
-.B -demux
-option is given, the N trajectories that are
-read, are written in another order as specified in the xvg file.The xvg file should contain something like:
-
-
-0 0 1 2 3 4 5
-
-2 1 0 2 3 5 4
-
-Where the first number is the time, and subsequent numbers point to
-trajectory indices.
-The frames corresponding to the numbers present at the first line
-are collected into the output trajectory. If the number of frames in
-the trajectory does not match that in the xvg file then the program
-tries to be smart. Beware.

-.B cluster
-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. Note that this will only give meaningful

-sets the location of the center of the box
-for options
-.B -pbc
-and
-.B -center
-. The center options are:
-
-.B tric
-: half of the sum of the box vectors,
-
-.B rect
-: half of the box diagonal,
-
-.B zero
-: zero.
-Use option
-.B -pbc mol
-in addition to
-.B -center
-when you

-
-
-With
-.B -dt
-it is possible to reduce the number of

-
-.B -timestep
-option to modify the time (this can be done

+\&* \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), note 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. Note 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.
+
+\&* \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
+\&octahedrons. 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

.SH DESCRIPTION
-trjorder orders molecules according to the smallest distance
-to atoms in a reference group. 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
-.B -da
-in the molecule and all the
-atoms in the reference group. All atoms in the trajectory are written
-to the output trajectory.
-
-
-trjorder 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 pdb 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
-.B -nshell
-the number of molecules within a shell
-of radius
-.B -r
-around the refernce group are printed.

.SH DESCRIPTION
-xpm2ps 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 do_dssp, g_rms or
-g_mdmat.
-
-
-Parameters are set in the
-.B m2p
-file optionally supplied with
-
-.B -di
-. Reasonable defaults are provided. Settings for the y-axis
-default to those for the x-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
-.B m2p
-file is supplied, many setting are set by
-command line options. The most important option is
-.B -size
-
-which sets the size of the whole matrix in postscript units.
-This option can be overridden with the
-.B -bx
-and
-.B -by
-
-options (and the corresponding parameters in the
-.B m2p
-file),
-which set the size of a single matrix element.
-
-
-With
-.B -f2
-a 2nd matrix file can be supplied, both matrix
-files will be read simultaneously and the upper left half of the
-first one (
-.B -f
-) is plotted together with the lower right
-half of the second one (
-.B -f2
-). The diagonal will contain
-values from the matrix file selected with
-.B -diag
-.
-Plotting of the diagonal values can be suppressed altogether by
-setting
-.B -diag
-to
-.B none
-.
-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
-.B -combine
-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
-.B -cmin
-and
-.B -cmax
-.
-
-
-
-.B -title
-can be set to
-.B none
-to suppress the title, or to
-
-.B ylabel
-to show the title in the Y-label position (alongside
-the Y-axis).
-
-
-With the
-.B -rainbow
-option dull grey-scale matrices can be turned
-into attractive color pictures.
-
-
-Merged or rainbowed matrices can be written to an XPixelMap file with
-the
-.B -xpm
-option.
+\&xpm2ps makes a beautiful color plot of an XPixelMap file.
+\&Labels and axis can be displayed, when they are supplied

+\&\- xtickfont, e.g. setting titlefont sets all fonts, setting xfont
+\&sets yfont, ytickfont and xtickfont.
+
+
+\&When no \fB m2p\fR file is supplied, many setting are set by

+\&With \fB \-f2\fR a 2nd 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

+\&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

+\&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
