Charmm atom type
WebNational Center for Biotechnology Information WebCHARMM atom types are usually upper cases, but it can have up to four characters for normal elements. In the following file conversions, atom types were adapted from AMBER to CHARMM if necessary. AMBER have two upper case letters for the atom types in protein and nucleic acid residues.

WebMass records in a MMFF-capable rtf file must also be augmented to add the atomic symbol for each CHARMM atom type after the atomic mass entry. Note that MMFF-capable rtf files are back compatible. That is, such rtf files can equally well be used for calculations that utilize the CHARMM force field. WebThis model uses CGenFF atom types and contains NBFix terms that, when too numerous, cause Anton error messages. It is highly suggested to use the following CHARMM36 lipid force field where cholesterol toppology and parameters are rolled back to the original c36 model (Biochemistry, 2004, 43, 15318) while all other lipids are kept the same.
