We've just downloaded and install the new dev-1129 release of phenix hoping to be able to run RS refinement on our twin structures. According to the change log it should be possible with this version.

------------------------------------------------------------------------

Version 1.8.1 and nightly builds (TBA)
======================================

- phenix.refine:
  - overall B-cart now applied to individual atomic B-factors (restores
    pre-1.8 behavior)
  - improvements to torsion NCS rotamer correction
  - real-space refinement for twinned structures

------------------------------------------------------------------------

Unfortunately, while trying to run - through the GUI - phenix dev-1129 with our twin setting and the "Real space" option, the usual message popped up: "PHENIX error: Real-space refinement is not available for twinned structures." FYI, it runs just fine without the "Real-space" option.

Did we have false hopes? Did we misunderstood? Is that a bug?

All the best,

Haim
