[gmx-users] how to make choices of COM in the system with freeze group

[tuyusong]

Hi, Users,

	I have a system with one carbon Nanotube and lots of water, in which
Nanotube is frozen. How do I remove the center-of-mass:

	1) only remove the COM of SOL
	2) remove both COM of SOL and CNT, separately
	2) only remove the COM of "system" as a whole.

How do I make the choices?

Thank you very much!!!

Yusong.
