Score distributions relative to the RMSD of ligand poses. The correct pose is shown in red and the other poses are in blue. A, B, C are for DIG18 and D, E, F are results for DIG20. A and D showed results using the Vina score, B and E used the consensus score, and C and F used PL-PatchSurfer. In C and F, the ligand poses that have an RMSD of 10 Å or higher to the reference binding pose of 1LKE were not scored because they were obviously dissimilar to the reference.
