Dear Mark Very thanks for your reply

Again, drug molecule is in region (1)in some frames and is in region (4) in other frames. ---------------------------------------------------------------------------------- Dear Justin Very thanks for your attention > As has already been stated several times, there is no problem at all. > The outcome is completely normal, and there are not discrete > regions (1) and (4). > It is a continuous block of water via PBC.

I want to calculate potential of mean force, delta G, as a function of the distance between the centers of mass of drug and the centers of mass of bilayer.
