Okay, this structure is a complete mess. For instance, look at residue 377. What do you want to do in a case like this? Actually throw an error, or try to soldier on and output whatever files happen to "work", such as it is?

[Eric Pettersen]

Actually this is a case where, because the coordinates are so bad, rebonding actually makes things worse. Of course, there are far more cases where rebonding improves things. Sigh.

[kristen.browne@…]

If this is a really bad structure, let me talk to Phil about replacing the file.  If it's something that's not trivial to fix and is an exception rather than a rule, we shouldn't try to accommodate.  Sometimes errors are there for a reason 😊

Phil says to "try to soldier on and output whatever files happen to "work", such as it is.  He wants to try and accommodate models that are at various stages of refinement.

Changed cx_unified.py so that if rebonding produces a mess (atoms with > 4 bonds), it reverts to the original bonds. Michal, it seems like GitHub integrated this latest change with the currently pending pull request.
