* Reference ligand
aCScore is a consensus scoring which uses multiple types of scoring functions to rank the affinity of ligands
bCrash-score revealing the inappropriate penetration into the binding site
CPolar region of the ligand
dG-score showing hydrogen bonding, complex (ligand–protein), and internal (ligand–ligand) energies
ePMF-score indicating the Helmholtz free energies of interactions for protein–ligand atom pairs (Potential of Mean Force, PMF)
fD-score for charge and van der Waals interactions between the protein and the ligand
gChem-score points for hydrogen bonding, lipophilic contact, and rotational entropy, along with an intercept term
