Re: [gmx-users] force field / parameters for NADH, FMN

Hi Justin, just for testing, I applied cgenff_charmm2gmx.py with charmm36-nov2016.ff as it has the same CGenFF version: --Version of CGenFF detected in /usr/local/gromacs/share/gromacs/top/charmm36-nov2016.ff/forcefield.doc : 3.0.1 But I still get the same warnings and errors. Would you

Dear Justin, thanks for the hint with the CHARMM-formatted topology and parameter files! That is great help! I had a different atom number compared to NAI and NADH because I had a different (non-physical) protonation state. The text drawing helped me a lot to figure out the few Nomenclature
