  1. Using the 3D structure of the wild-type complex as input file, the tool display details about the mutated chains, mutated residues, average distance of the mutated residue from its closest interacting partner, individual binding free energy change in Kcal/mol, average (predicted) binding free energy change in Kcal/mol, and the impact of each mutation on the binding affinity of the complex
