Thank you very much.
I attached my mdp file. Peptide locates on membrane surface. I want to know
about interaction between membrane and peptide, membrane permeability of
peptide, amino acids contribution for the penetration, specially energetic
values between the membrane and the peptide.
Please suggest me with helpful options?
How can I chose COM groups?
