Our Knowledge-base ORientational Potential (KORP-PL), developed in a joint-venture with Sergei Grudinin lab outperforms state-of-the-art statistical potentials using a 3D joint probability and a minimalist protein representation. Our side-chain independent potential is a fast and highly discriminative energy function for protein ligand docking, please have a try. Here you can find a mirror site of the methodology.
