Schrödinger Nodes for Suite2018-1 version 0.0.1.7B27VcMf4_L7A58S5A8G55JS by Schrödinger
This node runs a MacroModel Rigid Rotor Harmonic Oscillator (RRHO) calculation to obtain the change in translational, rotational, vibrational, and total entropy of the ligand upon binding. It generates a table with the entropies ( T*dS_translational, T*dS_rotational, T*dS_vibrational and T*dS_total). Optionally, the input Maestro file can be included in the output table.
The conformational entropy is not computed, since that would require a thorough sampling of the energy landscape of the ligand both in the environment of the protein and in solution in order to obtain the partition function.
Note that this node takes a pose viewer file as input, i.e. a Maestro file that has the receptor as it first entry followed by the ligands.
