NAME

g_dist - calculates the distances between the centers of mass of two groups

SYNOPSIS

g_dist -f traj.xtc -s topol.tpr -n index.ndx -o dist.xvg -[no]h -nice int -b time -e time -dt time -[no]xvgr -dist real

DESCRIPTION

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.

Other programs that calculate distances are g_mindist

and g_bond
