Thank you so much for that, Justin. Now I could expand the bilayer.
I've another query. My protein has a small N-terminal portion embedded in the membrane, I would like to insert only this part into the membrane during 'packing the lipid around the protein' step in your tutorial. Initially I was trying to do simulation only with this TM region and then attaching the rest of the protein with this TM region and simulate the whole system. But was time-taking. Can you please guide me to pack the lipid bilayer only around a 33-residues long peptide in my protein and rest with water?
