Discussion

• ChimeraX 1.5 release
  • Decided to branch today
  • Release candidates made on Thursday if no big bugs seen in daily build.

• Floating tool panels
  • Discussed whether there should be an option for floating tool panels to always stay in front.
  • Eric changed behavior on Mac only so they do not stay in front.
  • Tristan said this change caused panels to be completely hidden behind the main window when he uses ISOLDE with ChimeraX full-screened.
  • Eric will work with Tristan to see how best to solve this.
  • Behavior of floating panels differs on Mac, Windows and Linux. Should investigate all 3.

• DICOM mispositioned model
  • Elaine reported one image being very far from others in opening some DICOM data.
  • Zach wonders if can be related to rearranging the model hierarchy as models opened. Tom says probably not.
  • Eric suggests looking at model.position.matrix for the offending model and its parent and higher ancestors to see which one is mispositioning it.
  • Can compare to the ChimeraX 1.4 positioning to see where the difference lies.
