WebAug 17, 2024 · The CHARMM General Force Field (CGenFF) program performs atom typing and assignment of parameters and charges by analogy in a fully automated fashion. Atom typing is done by a deterministic programmable decision tree. Assignment of bonded parameters is based on substituting atom types in the definition of the desired parameter. http://www.mdtutorials.com/gmx/complex/02_topology.html
