Possible? Yes.
Automatic? No.

It would require quite a bit of custom vmd scripting. Not very difficult, but you would have to combine different pieces of scripting that have been discussed before.

Subject: vmd-l: Atomic trajectory to COM trajectory,

Dear All users,

I have done an NVT ensemble with LAMMPS package. I have saved its
trajectory in trr format.

Now, I want to convert that atomic trajectory to trajectory of center of
mass of molecules. Is it

possible? Does any body have experience? I want to do this for calculation
of density and g(r)

values of COMs in VMD. Can I save the coordinates of atomic trajectory of
atoms as COM

trajectory?
