Docking results on the unbound dataset using meta-PPISP prediction are classified by the docking difficulty. The same results shown in Figure 7 are classified into three docking difficulty classes, rigid-body (87 cases), medium (16 cases), and, difficult (15 cases). A, B, results using 2.5 Å and 4.0 Å, respectively, for the iRMSD cutoff value to define correct prediction. Black/red circles, the rigid-body category results by PI-LZerD/LZerD; green/yellow triangles, the medium category by PI-LZerD/LZerD; Black/red squares, the difficult category by PI-LZerD/LZerD.
