Dear Users,
I want to simulate POPC membrane with CHARMM ff using GROMACS 4.6.5.
but in CHARMM ff directory, there is no popc itp file. How can I proceed?
Download the CHARMM36 files from our site:
http://mackerell.umaryland.edu/charmm_ff.shtml#gromacs
The lipid parameters in CHARMM36 are considerably better than those in CHARMM27,
which is what is packaged with Gromacs.
Then just process with pdb2gmx; we include POPC in the .rtp file.
