; OPLS atom types and masses. ; Atom types are named opls_X, where X is the OPLS number. ; The opls_ prefix is to avoid users confusing atom types ; (always prefixed) with atom numbers in molecules (never prefixed). ; ; Types 1-134 are from the united-atom OPLS, which can be ; useful for solvents and/or CH2 optimizations (e.g. in lipids). ; Explicit all-atom parameters start with opls_135. ; Note: For UA amide parameters - ; NMA - types 1,2,3,4,7,39 ; Formamide 131,2,12,13 ; DMF 131,2,3,132 ; Acetamide 1,2,7,12,13 ; ; Types 1-65 are united-atom parameters for proteins, ; see JACS 110, 1657 (1988). ; opls_001 12.01100 ; opls_002 15.99940 ;
