Hi phenixbb/developers, Recently, some people have experienced problems with B-factor refinement in the official releases of PHENIX. It seems to me that, generally speaking, the first suggestion is to use the nightly builds of phenix. So, my question is: How does the official releases work? Is it a snapshot of the development version, or are you doing some kind of stabilization during the development of the official releases? Are you updating the official releases after release (to fix bugs) or are the bugs only fixed in the nightly builds. With the current official releases, would I be better off using the nightly builds for refinement? (I have also seen some weird behavior with B-factor refinement). Best regards and thank you for developing phenix, Folmer -- Folmer Fredslund Post doc MAX IV Laboratory Lund Sweden
