| VERSION 3.0 |
g_traj plots coordinates, velocities, forces and/or the box. With -com the coordinates, velocities and forces are calculated for the center of mass of each group. When -mol is set, the numbers in the index file are interpreted as molecule numbers and the same procedure as with -com is used for each molecule.
Option -ot plots the temperature of each group, provided velocities are present in the trajectory file.This implies -com.
Option -ekr plots the rotational kinetic energy of each group, provided velocities are present in the trajectory file. This implies -com.
