Discussion

• EMAlign toolshed problem
  • Wheel unusable because Toolshed added a suffix to the wheel file when two submissions with the same version number were made.
  • Greg will look into it.
  • Developer Yuval will be asked to submit with a higher version number to fix the problem for now.

• Chimera release to fix PDB fetch
  • Eric will add to release notes PDB fetch issue
  • Greg will make Chimera release, hopefully by Thursday.

• Scenes pull request
  • Discussed whether scene saving needs unique ids. For now let's try without that.
  • Code to save atomic structures belongs with Structure class, not in Collections.
  • View scene save and restore should not make new instances of Lighting, Material, Camera... and those objects should restore their state, avoid having View save grandchild state.
  • Eric or Zach will accept Piet's pull request.
  • Piet will make a new pull request to fix the above problems.
