DockScore is a rigorous scoring scheme which can be used to rank the docked poses and identify the best docked pose out of many as proposed by docking algorithm employed.
DOCK addresses the problem of “docking” molecules to each other. In general, “docking” is the identification of the low-energy binding modes of a small molecule, or ligand, within the active site of a macromolecule, or receptor, whose structure is known. A compound that interacts strongly with, or binds, a receptor associated with a disease may inhibit its function and thus act as a drug. Solving the docking problem computationally requires an accurate representation of the molecular energetics as well as an efficient algorithm to search the potential binding modes.
