| | GAFF |
 | | 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 great amount of molecules (such as database searching) in an automatic fashion. |
 | | The van der Waals parameters of GAFF are as same as those used by the traditional AMBER force field. |
 | | First of all, it is a complete force field, which means all the parameters are available, no parameter-missing happens to GAFF; secondly, this force field is very general and it covers almost all the organic chemical spaces; finally, GAFF is compatible to the AMBER force field. |
