GROMACS version:
GROMACS modification: Yes/No
Here post your question Hello, I am not completely sure this questions belongs here, but I am trying to run a md simulation using GROMACS with the CHARMM36_ljpme forcefield as downloaded from the MacKerell Lab page. For my simulation I wanted to use the Gram Positive membrane that is deposited in CHARMM-GUI Archive - 18 Biomembranes G+PM (cell membranes of Gram-positive bacteria). However when trying to generate a topology file using pdb2gmx I get the following:
Fatal error:
Residue ‘AIPG’ not found in residue topology database
Anybody knows how can I add the topologies of lipids found in CHARMM Topology Files - Additional topologies and parameters for lipids toppar_all36_lipid_bacterial.str to my forcefield in my working directory?
Looking forward to any answer of hint as to where it would be better to ask around!
