I'm having a strange issue with the beta version of PyRosetta (using 64bit Ubuntu). The phi,psi dihedral angles corresponding with an alpha-helix, when applied to a 20-mir polyA structure (this is simply from the tutorial) returns an alpha-helical structure as expected. But the dihedral angles corresponding with a beta strand (-135,140) returns a completely incorrect, wheel like structure. It's as if the changes weren't applied. Could someone confirm this with their 2.0 build?
Post Situation:
Have you also set all of the omega angles to 180?
