GAFF force field

GAFF (general AMBER force field) is designed for rational drug design. GAFF is compatible to the AMBER force field and it has parameters for almost all the organic molecules made of C, N, O, H, S, P, F, Cl, Br and I. As a complete force field, GAFF is suitable to study a large number of molecules in an automated fashion.
