Automatic torsional angle detection for conjugated polymers. PySoftK offers a tool to perform analysis of the torsion angles within conjugated polymers that connect the ring subunits that are commonly found in their backbone. These dihedrals are generally poorly captured by the existing parameters within classical forcefields. Thus having the capability to rapidly identify those dihedrals then allows the user to easily set up the necessary ab initio simulations required to determine the potential energy landscape of those dihedrals, which then can be used to reparameterize the forcefield for those dihedrals.
