Docking results are ranked by docking scores (the more negative the better), which indicates how well the ligand is predicted to bind to the target. It is, however, also important to check the binding mode and analyze whether it is in agreement with a priori knowledge. | Docking results are ranked by docking scores (the more negative the better), which indicates how well the ligand is predicted to bind to the target.
