Figure 2From: TSCC: Two-Stage Combinatorial Clustering for virtual screening using protein-ligand interactions and physicochemical featuresDesigning a reference threshold of P-L interaction and atom-pair descriptors. The complementation between atom-pair descriptor and the protein-ligand interaction descriptor is also show in this figure. The distance threshold of atom-pair descriptor was 0.55 (tanimoto coefficient). The threshold of distance of protein-ligand interaction descriptor was 0.39 (correlation coefficient).Back to article page
