[gmx-users] CHARMM-GUI files give error in Gromacs

[gozde ergin]

Hi Justin,

I try to use the CHARMM-GUI files directly. My purpose is simulating the water and ci-pinonic system. Cis-pionic molecules will stay on the water surface and I would like to estimate surface tension reduction. 

What should I change in CHARMM-GUI files?

It is a subset of the full CHARMM force field plus any parameters that are newly introduced by your non-standard molecule.  Are you using only files directly from CHARMM-GUI, without modification, or are you trying to do something else?
