0000138: InterfaceAnalyzer mishandles cross-interface disulfides
InterfaceAnalyzer fails to treat cross-interface disulfides as broken in the separated state, leading to grossly incorrect dg_separated values, poisoned by about 6000 REU worth of disulfide energies. It is unclear how it should treat interfaces linked by a cross-chain disulfide.

A) Refuse to score such poses?

B) Perhaps score as disulfide in the complex case, and score as not-disulfide in the separated case (with repackable cysteines)?

C) Perhaps B but in both cases multiply the disulfide terms by zero post-scoring? (turning them off in the scorefunction may result in incorrect packing?)
