g_saltbr_d

NAME

g_saltbr - computes salt bridges

SYNOPSIS

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

DESCRIPTION

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

Output will be in a number of fixed filenames, min-min.xvg,min-plus.xvg and plus-plus.xvg, or files for every individual ion-pair if selected
