QuickFF is a software package to derive accurate force fields for isolated and complex molecular systems in a quick and easy manner. The force field parameters for the covalent interaction are derived from ab initio data, i.e. an equilibrium structure and a Hessian matrix, which needs to be produced by the user. QuickFF is a tool that can easily be used by anyone with a basic knowledge of performing ab initio calculations. As a result accurate force fields are generated with minimal effort.
