Hello, I have my system with DMPC bilayers in pdb and try to convert it into GROMACS input. Because system is with lipids I think chose CHARMM27 ff. But still I get lots of warnings like that: https://pastebin.com/K8dHKkUi Also I add my DMPC pdb as example. What should I do? Rename all my DMPC atoms?Thanks for all suggestions.
