[gmx-users] Charmm ff compatibility with Gromacs

[maria khan]

Hello Gromacs users..

Charmm 37 ff is for charmm and Namd which is all atom ff using codes,,and
gromacs is united atom so how can its results will be reliable as these are
different things??.My protein of interest is having DNA..

Secondly how can i find ff parameters for my ligand of interest?? also if
ff parameters are not in published form then it means i will not be able to
use that ligand for MD run??

Regards..
