Since the update, on both my solo and our team protein (Contenders), the local wiggle is behaving strangely. A local wiggle on virtually every 2-5 segment area results in an immediate point drop, and then the score jumps back and forth dramatically - sometimes 10pts or more. My protein wasn't reacting this way to local wiggles yesterday. Obviously there were always areas that would have a point drop due to the backbone adjusting to a new (and not optimal) position during a local wiggle, but this is different. I'm basically unable to rebuild or local wiggle at all right now. Is anyone else having this same issue? Was the local wiggle changed in some way that we have to adjust to?

If you Include the protein end in the local wiggle, it behaves correctly. If the local wiggle is being performed on an enclosed section of the protein (ie not including an end) it behaves as described by Montecristo above.

In addition, the cookbook 'local wiggle sequence' does not produce any results at all when local wiggling. It correctly sequences through the protein sections, the section starts to 'color pulse' as though it is wiggling, but there is no effect on the score. Are the two problems related ?

Does this happen on the starting structure or structures that were heavily local wiggled before the update?

After 'Reset Puzzle' local wiggles on two segments give fluctuating scores during the wiggle on most sections sellected. The fluctuations are not as large (+/- 2 pts), but the behaviour is similar and doesn't look correct.

Thanks for pointing this out. I think this is due to some tuning of the internal parameters of local wiggle. I've readjusted them to hopefully behave better, and I'll post an update with that shortly.

Thanks for working on this, I really, really appreciate it.

Did the new update resolve this issue?

I don't have my protein to the stage I was at on the last puzzle, where I saw the odd behavior, but it seems to be working fine now. I know that even when I reset 138, it was still acting strange. The local wiggles now act like they used to - or at least very close. There are no dramatic point drops unless the backbone readjusts due to major stress on it. I don't know if it was intentional, but I also noticed that you can now local wiggle a single segment. It seems to work to straighten the backbone and score points.
