Discussion

• Handling invalid input parameters
  • Eric looking for a good way to tell the user about invalid input parameters in a GUI panel after they press OK.
  • Raising user error shows dialog that raises main window and floating input panel ends up behind main window.
  • Discussed instead showing QErrorDialog instead of user error to avoid raising main window.

• Qt update
  • Updated from Qt 6.7 to 6.8.2 in the nightly build.
  • Hoping this fixes mac multiple display crashes.

• Nightly builds failing
  • Zach is fixing nightly builds that failed over the weekend.

• Chimera end-of-life changes.
  • Might stop requesting annual registrations.
  • Also stop showing bug report dialog.
  • Eric currently closes lots of Chimera bugs with wont-fix since they are Tk problems and we won't update Tk.

• ViewDockX
  • Piet asked how manager/provider callbacks work for use in new ViewDockX implementation.
  • Eric explained system and why to use it.
  • Formats for docking can be registered as providers using the ViewDockX manager.

• Acer SpatialLabs 3D display
  • Discussed how lenticular stereo on Acer 3D display might work and whether it would reduce 4K pixel resolution to half the number of pixels per eye.

• Boltz-1 on Mac
  • Tom ran Boltz on Mac with decent speed, on Mac Studio 2 minutes, 1 minute on minsky nvidia 4090, and 3 minutes MacBook Pro, for 600 amino acid nipah protein and drug.
