Yes....I have already done as wrote....
My question is....what if I up load ligand surface with receptor structure?
Will it, as I think, shows me the potential of ligand on the receptor surface (giving me as sort of negative of ligand surface on receptor's)???
Thank for your answer,

You need to "create" individual proteins and then create maps for the
individual protein;  e.g, create A,(structure and residues_of_A_only)

I think, but I would have confimations, that I am, in some way, "projecting" potential values of protein's  surface B on the surface of protein A, like having a "negative" of the B interactions. It seems it works like this since I know both rotein's interacting residues and now I am facing interacting patch of residues from protein B on their counnter part on protein A.
