Dear Users,

I am confused by the options of the PBC tool. Currently I have last frame
of a membrane in water simulation. As I have turned on "Wrap ALL" during
simulation, the system "trapped" inside a box and now water is in the
middle of the box and two layers of membrane are splitted into the top and
bottom. I would like to unwrap this thing back to my initial configuration
- two-layer in the middle and water above and below so what should feed to
pbc unwrap?

I have made tons of trials and still cannot work out. I will appreciate any

Thanks in advance,
