Greetings GrOmAcS Users,

I want to calculate the free energy, for different (de)protonation states, of a certain compound.
This requires to edit by hand many topology files.

Is there a code that can do it on-the-fly or any ideas(algorithm) how it can be done automatically?


Since you'd need to add/remove the proton and perhaps change the atom type to which it was bound and maybe its other proton atom types, it is hard to come up with a general algorithm that is worth the time to implement.
