Table 1 Binding affinity prediction by Vina for the DUD-E dataset. Experimental and predicted binding sites are used in molecular docking with the default and optimized box sizes. Average values and the corresponding standard deviations are reported separately for active and decoy compounds; p-values are calculated using the Mann–Whitney U test
