Correlation evaluation of the PHOENIX scoring function on the PDBbind 2004 (n = 1073) refined set. Correlation statistics include number of complexes tested (N), Pearson correlation coefficient (R_p), standard deviation (SD), mean error (ME), slope (a) in the linear regression (y = ax + b), and intercept (b). Results from the X-Score scoring functions are presented for comparison purposes.

Scoring Function	Rp	Rs	SD	ME	a	b
PHOENIX	0.515	0.554	2.00	1.57	0.35	4.46
X-Score::HPScore	0.557	0.589	2.00	1.57	0.32	4.24
X-Score::HMScore	0.540	0.572	2.06	1.63	0.29	4.23
X-Score::HSScore	0.561	0.593	1.95	1.53	0.36	4.27
