I have different homology models for a protein, and I want to measure the shape complementarity against another protein. I already know how these proteins are interacting and my hommology models are based in the pdb of the proteins interacting, so I guess that a docking analysis is not mandatory and also because I have tried this but the results are so different. So, I am looking for a software or server that could measure shape complementarity between two proteins taking as an input the homology model of the pair interacting.
