Thank you Mark. The problem is, in order to use the couple-moltype option
for decoupling, I want to keep the two proteins in separate moleculetype(s).
Now I noted that Gromacs has a pull option for doing umbrella sampling, but
I don't know how it might be used to apply distance restraint between two
atoms belonging to two molecules.
Any susggestions on how the pull code can be utilized is very much
