I am using Modeller to include mutations in the interface of
protein-protein complexes. One of the crucial parts of my work here is
to characterize and improve the available methods including water at the
interface, and I wanted to use the restraints related with hydrogen bond
energy since I think they are very important in this. However, I can not
find in the documentation how to use the Physical.h_bonds as a
restraint, since I don't know how this energy function is defined and
what is its input.
