Charmm27
WebThe current versions of the CHARMM forcefield are CHARMM22 for proteins and CHARMM27 for lipids and nucleic acids including CMAP correction to proteins. The individual topology files are named, respectively, top_all22_prot_cmap.inp, top_all27_lipid.rtf, and top_all27_na.rtf. Webpdb2gmx input files#. The GROMACS program pdb2gmx generates a topology for the input coordinate file. Several formats are supported for that coordinate file, but pdb is the most commonly-used format (hence the name pdb2gmx). pdb2gmx searches for force fields in sub-directories of the GROMACS share/top directory and your working directory.
