Hi,

I'm performing a transmembrane protein simulation in an explicit DPPC bilayer. I manually removed the lipids to accomodate my protein and the system has undergone 15 ns of equilibration.

In removing the lipids, I a gap betwteen the protein and membrane resulted. Most of the lipid molecules aggregated around the protein, but I have found that on one side of the protein, there are some water molecules that have found their way between the protein and lipid bilayer. Is there any way of removing these by altering the simulation parameters, or will I have to remove them manually?

See http://wiki.gromacs.org/index.php/Membrane_Simulations... these waters may have been present in your initial structure.

I already constrained the waters in the z-direction at the start of the simulation, so that didn't work in this case.

I don't understand this.
