Hi,

I have some protein-ligand complexes and I want to calculate HADDOCK energy for them. Is it possible to skip the docking step and get HADDOCK binding energy of the bound complexes? If so, can anyone please guide me on where to start?

You could use the refinement interface of the server for that with the simple energy minimization refinement
