fftk-sample-medThe force field toolkit (FFTK) is a plugin for the visualization and analysis software VMD.  FFTK is comprised of a set of tools that aid users in the development of CHARMM-compatible forcefield parameters, including charges, bonds, angles, and dihedrals. These tools are accessed through the provided GUI, which greatly simplifies the setup and analysis of the underlying calculations. Currently, the toolkit assumes that all QM target data is generated using Gaussian; however, we plan to expand functionality to include alternatives.  More details about FFTK can be found on its official webpage.
