All-Atom Four-Body Knowledge-Based Statistical Potentials to Distinguish Native Protein Structures from Nonnative Folds
Table 3
Performance evaluation on 145 benchmarks in 8 decoy sets from Decoys-‘R’-Us, based on energies obtained with the four-body potential derived using a 4-letter alphabet and 12 Å cutoff as parameters.

Native rank = (rank of native structure with given PDB ID)/(total number of decoys); a rank of 1 is optimal and means the calculated energy of the native structure is lower than that of all its decoys; = correlation coefficient; FE = fractional enrichment.
