WebBy design, GAFF, is a complete force field (so that missing parameters rarely occur), it covers almost all the organic chemical space that is made up of C, N, O, S, P, H, F, Cl, Br and I. Moreover, since GAFF is totally compatible with the AMBER macromolecular force fields it should prove to be a useful molecular mechanical tool for rational ... Webin GROMACS provides better computing performance with better scalability than the implementation in NAMD. This difference arises because the random force is implemented inside the MD code in GROMACS rather than in a tcl script as for NAMD, for details see Ref. o We usually use the Amber ff14 and Gaff force fields for the protein and the ligand, punisher s2
