The CHARMM parameters are available for download from the MacKerell web site: To be used simultaneously, it is preferable to use these pre-combined files. While the tools used with NAMD allow multiple topology and parameter files Par_all27_prot_na.prm which can all be found in the CHARMM31 release. Par_all27_na_lipid.prm, par_all27_prot_lipid.prm, and To enable hybrid systems, combinations are also provided, named Par_all22_prot_cmap.inp, par_all27_lipid.prm, and The individual parameter files are named, respectively, The current versions of the CHARMM forcefield are CHARMM22 for proteins andĬHARMM27 for lipids and nucleic acids including CMAP correction to proteins.
