[gmx-users] mass center of each molecule

Dear gmx users,
I want to calculate the center of mass of each molecule in the system all
through the simulation time.
When I used "g_traj -f traj.xtc -s topol.tpr -n index.ndx -ox coord.xvg
-com'' command, I obtained the center of mass of the system
I tried some ways to get the mass center of each molecule but I was not able
to successful find it.
Similarly I need the inertia axis of each molecule all through the
simulation time but again I found
the average values at each step.
Could you please tell me how I can easily do these calculations by Gromacs
Thanks in advance,
