NAME

       g_saltbr - computes salt bridges

       VERSION 4.6.5

SYNOPSIS

       g_saltbr  -f  traj.xtc -s topol.tpr -[no]h -[no]version -nice int -b time -e time -dt time
       -t real -[no]sep

DESCRIPTION

        g_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.
