g_saltbr(1)

NAME
g_saltbr - computes salt bridges VERSION 4.6.3

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.
