A. Five methods in training set, submitted testing set, and retrospective best predictions for testing set. Optimal receptors for align-cross, min-cross and dock-cross were (prospectively) 4OBP, 4OBP, MAP03 and (retrospectively) MAP29, MAP16, 4U45, respectively. Overall, min-cross and align-cross performed better in our submitted predictions. N: number of co-crystals, I: number of co-crystal with IC50 data, P: number of compounds for prediction. B. Comparison of several pose related methods. (Spearman ρ and R2 are generated by comparing the Vina scores from different methods and experimental IC50 data).
