Dear VMD users,

I have run a simulation of protein inside lipid bilayer. It looks like
during the simulation the lipid bilayer has moved in the z-direction
significantly. I want to fix the centre of mass of the lipid bilayer at the
origin so that through the whole simulation trajectories it keeps at the
same position. I am wondering how can I do that.
I have used the following command to do that but it did not work,
*pbc wrap -sel "segid MEMB" -center origin -compound residue -all*

Can anyone please help me?
