a - Moldock score is derived from the PLP scoring functions with a new hydrogen bonding term and new charge schemes. (Thomsen and Christensen 2006).
b - The rerank score is a linear combination of E-inter (steric, Van der Waals, hydrogen bonding, electrostatic) between the ligand and the protein, and E-intra. (torsion, sp2-sp2, hydrogen bonding, Van der Waals, electrostatic) of the ligand weighted by pre-defined coefficients. (Thomsen and Christensen 2006).
c - The total interaction energy between the pose and the protein (kJ mol⁻¹).
d - The internal energy of the pose.
e - Hydrogen bonding energy (kJ mol⁻¹).
f - Ligand Efficiency 1: MolDock Score divided by Heavy Atoms count.
g - Ligand Efficiency 3: Rerank Score divided by Heavy Atoms count.
