Correlation evaluation of the PHOENIX scoring function compared to X-Score scoring functions on high- (0 ≤ 2 Å) and low-resolution (2 ≤ 2.5 Å) complexes of the PDBbind 2002 set. Correlation statistics presented are the number of complexes tested (N), Pearson correlation coefficient (R_p), standard deviation (SD), mean error (ME), Spearman correlation coefficient (R_s).
