NESGMX

This cubes runs the forward and reverse Bound and Unbound starting equilibrium frames by using Gromacs for each edge. The physical work associated with the edge mutations are calculated by using the Thermodynamic Integration method and saved on the record ready to be analyzed.

Input

Data record Stream - Streamed-in of records containing Gromacs equilibrium frames data for the forward and reverse Bound and Unbound calculations

Output

Data Record Stream - Streamed-out of records containing work data used to generate relative binding affinity data.
