  1. The PDB code, the number of decoy conformations (N), the RMSD range of the decoys relative to the experimentally determined conformation, the RMSD ranking of the best-scoring conformation, the log probability of selecting the best-scoring conformation (log PB 1), the log probability of selecting the lowest RMSD conformation in the top 10 best scoring conformations (log PB 10), the fraction enrichment of the 10% lowest RMSD conformations in the top 10% best scoring conformations (F.E.), the correlation coefficient between scores and RMSDs (C.C.), the Spearman's rank correlation coefficient between scores and RMSDs (R.C.), the ranking of the experimentally determined conformation relative to the decoy conformations based on density scores (R exp ), and the correlation coefficient calculated by the original formula used by Simons et. al. [27] (C.C. orig ) are shown. In general, the density score function performs very well, with dependence on the properties of the decoy sets.
