Our Knowledge-base ORientational Potential (KORP) utilizes a 6D joint probability and a minimalist representation to outperform state-of-the-art statistical potentials for protein and loop modeling. Our side-chain independent potential is a fast and highly discriminative energy function, please have a try.
