Merge pull request #4665 from RosettaCommons/vmullig/fix_dorn_bug
Fix a symmetry bug with NCAAs.
The BACKBONE_AA option was not properly being mirrored by the D_AA patch. This affected the rama_prepro and p_aa_pp scoreterms for D-NCAAs.
This PR also updates some tests that were performing redundant tests of beta_nov15 (which is now our ref2015 default scoring function) to test whatever the current beta scorefunction is.
