g_dist(1) GROMACS suite, VERSION 4.5.4-dev-20110404-bc5695c g_dist(1)NAMEg_dist - calculates the distances between the centers of mass of two groups VERSION 4.5.4-dev-20110404-bc5695cSYNOPSISg_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 realDESCRIPTIONg_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 continuously present. Other programs that calculate distances are g_mindist and g_bond.FILES-f traj.xtc Input Trajectory: xtc trr trj gro g96 pdb cpt -s topol.tpr Input Run input file: tpr tpb tpa -n index.ndx Input, Opt.
