[gmx-users] center of mass motion

Dear all,

is there an EASY way to calculate the center of mass of a group of atoms
as a function of time (and possibly print it out as a whatever.xvg file)?
I found that the g_dist program calculates the distance between the
centers of mass of two groups of atoms as a function of time, which is
different from what I need. Anybody has suggestions?

Thanks a lot
