Discussion

• Deleting ChimeraX file history thumbnails
  • Eric suggests an Edit mode from context menu can show checkbuttons next to each thumbnail and clicking those can run a ChimeraX command to delete that entry.

• Chimera Trac database locked
  • Greg sees Watson has load average of 30, possibly related.
  • Watson has 37 Modeller jobs running.
  • Greg saw other problems on Watson and will reboot it tonight.

• Release candidates
  • ChimeraX 1.6 release candidates not yet made because Github changed their ssh private key. Then daily build lock file blocked builds. Zach has restarted builds.
  • Eric is fixing distance to centroids bug.
  • Zach is fixing new nfti file reader voxel size problem.
  • Tom will try to suppress setDarkBorderToWindow warning on Windows.
  • Tom will investigate Mac panels blank after deiconifying.
  • Greg is working on making a linux flatpak distribution.

• Qscore tool from Tristan
  • Measures fit of each atom to density, method developed by Greg Pintilie, and used by EMDB.
  • Tom offered to put Tristan's new QScore tool into ChimeraX 1.6.
  • Needs user interface fixes and documentation.
  • Tristan has provided wheels on all 3 platforms.

• Pandas
  • Zach removed unused and large pandas dependency from tcia_utils to keep size of ChimeraX distribution down.

• Mac dmg file arrow to drag to Applications
  • Zach or Tom can look at adding arrow and Applications folder to ChimeraX dmg so users know not to run it directly from dmg.
