PolyParGen Manual

PolyParGen provides OPLS-AA and Amber force field parameters for polymers or large molecules. In the case that PolyParGen generates OPLS-AA parameters, PolyParGen leverages LigParGen [2] and BOSS [3]. On the other hand, PolyParGen leverages Antechamber [4] and ACPYPE [5] to make Amber parameters. If users want to use the atomic charge of ab initio calculation, user just select the option of ab initio calculation. Ab initio software is NWChem [6].

This site shows how to use the PolyParGen.
