NAME
g_dist - calculates the distances between the centers of mass of two groupsVERSION 4.5
SYNOPSIS
g_dist -f traj.xtc -s topol.tpr -n index.ndx -o dist.xvg -lt lifetime.xvg -[no]h -[no]version -nice int -b time -e time -dt time -xvg enum -dist realDESCRIPTION
g_dist can calculate the distance between the centers of mass of two groups of atoms as a function of time. The total distance and its x, y and z components are plotted.Or when -dist is set, print all the atoms in group 2 that are closer than a certain distance to the center of mass of group 1.
With options -lt and -dist the number of contacts of all atoms in group 2 that are closer than a certain distance to the center of mass of group 1 are plotted as a function of the time that the contact was continously present.
Other programs that calculate distances are g_mindist and g_bond.
