--------------------------
= Discussion =

* ChimeraX 1.9 bugs
  - Eric reports a few 1.9 bug reports that may or may not be serious.
  - Some 1.8 sessions involving sequences don't restore in 1.9.
  - KVFinder crashes ChimeraX on Windows for some structures.

* Crash reporting on Windows
  - Greg says Windows ChimeraX does not start with Python -X faulthandler command-line option.
  - That may be why Eric did not get asked to report crash in KVFinder test.
  - Need to investigate if all crash reports on Windows are disabled.

* Home directories on NAS
  - Greg moved Chimera, cxtoolshed, Elaine, TomF plato home directories from beegfs to NAS.

* cx_developers script error "django not found"
  - Possibly caused by moving cxtoolshed home directory to NAS.
  - Greg sees hard-coded /wynton paths in the python venv activate script called before running script.

* Cannot remove directories on plato
  - Eric was unable to remove nobackup/essex directories in his home directory on plato even though he has ownership and permissions (he rsynced them there).
  - Greg says sometimes beegfs metadata server corruption after disk problems could cause this.

* ChimeraX developer tutorial: keywords
  - ChimeraX outside developers often use no keyword arguments, only postional ones in commands.
  - Tutorial example does not show keyword option.
  - Eric will look into adding a keyword example.
  - Eric might add a section extolling virtues of keyword options over optional options.

* Volume attributes for scenes
  - Piet asked about what attributes of volumes are important for scenes.
  - Tom described styles, thresholds, colors.
  - Greg suggests Piet document API to add a new model type to scenes and Tom add volumes.
