Thank you Herbert, Yes, I call tunneling the "conformer swap trick", and I provide a jiffy script for doing this. Swapping conformer letter assignments is equivalent to changing the color of the ropes at a certain distance down their length.  When you give this to the refinement program all

Update: I've gotten some feedback asking for clarity on what I mean by "tangled". I paste here a visual aid: The protein chains in an ensemble model are like these ropes. If these ropes are the same length as the distance from floor to ceiling, then straight up-and-down is the global

Greetings Everybody, I present to you a Challenge. Structural biology would be far more powerful if we can get our models out of local minima, and together, I believe we can find a way to escape them. tldr: I dare any one of you to build a model that scores better than my "best.pdb" model
