WebComputation of intermolecular interactions is a challenge in drug discovery because accurate ab initio techniques are too computationally expensive to be routinely applied to drug–protein models. Classical force fields are more computationally feasible, and force fields designed to match symmetry adapted perturbation theory (SAPT) interaction …
WebA force field is included at the beginning of a topology file with an #include statement followed by .ff/forcefield.itp. This statement includes the force-field file, which, in turn, may include other force-field files. All the force fields are organized in the same way. An example of the amber99.ff/forcefield.itp was shown in Topology file. http://mackerell.umaryland.edu/charmm_ff.shtml
