NAME

       gmx-saltbr - Compute salt bridges

SYNOPSIS

          gmx saltbr [-f [<.xtc/.trr/...>]] [-s [<.tpr>]] [-b <time>] [-e <time>]
                     [-dt <time>] [-t <real>] [-[no]sep]

DESCRIPTION

       gmx  saltbr  plots the distance between all combination of charged groups as a function of
       time. The groups are combined in different ways.  A minimum distance can be given (i.e.  a
       cut-off), such that groups that are never closer than that distance will not be plotted.

       Output   will   be   in  a  number  of  fixed  filenames,  min-min.xvg,  plus-min.xvg  and
       plus-plus.xvg, or files for every individual ion pair if the -sep option is  selected.  In
       this case, files are named as sb-(Resname)(Resnr)-(Atomnr).  There may be many such files.

OPTIONS

       Options to specify input files:

       -f [<.xtc/.trr/…>] (traj.xtc)
              Trajectory: xtc trr cpt gro g96 pdb tng

       -s [<.tpr>] (topol.tpr)
              Portable xdr run input file

       Other options:

       -b <time> (0)
              Time of first frame to read from trajectory (default unit ps)

       -e <time> (0)
              Time of last frame to read from trajectory (default unit ps)

       -dt <time> (0)
              Only use frame when t MOD dt = first time (default unit ps)

       -t <real> (1000)
              Groups that are never closer than this distance are not plotted

       -[no]sep (no)
              Use separate files for each interaction (may be MANY)
