ANDIS is an atomic angle- and distance-dependent statistical potential devoted for protein structure quality assessment. Five angles are calculated for each atom-pair with distance < dcut (dcut is adjustable from 7.0 to 15.0 Angstrom) and residue separation ≥ 7 in protein structure. The observed frequencies of atom-pair distances and corresponding angles are converted to a combined statistical potential based on the inverse Boltzmann law. ANDIS naturally integrates the atomic orientation-dependent and distance-dependent interactions. We benchmarked ANDIS with a comprehensive list of publicly available statistical potentials. ANDIS demonstrate a significantly better ability of native recognition than the other tested potentials.
