Discussion

• Plato file migration to NAS
  • Greg says Wynton files for Plato (services, web, ...) have mostly been moved to the Network Attached Storage on plato and plato is using the NAS versions.
  • Home directories have not been moved.
  • Mail spool directories have not been moved.
  • If home directories are moved then logging in to Wynton won't find home directory, because they currently use the same account through the same LDAP server.
  • If plato nodes removed from Wynton, may need separate accounts and separate LDAP to manage plato account separately from Wynton.

• ChimeraX 1.9 release
  • Greg will remilestone or close some tickets.
  • Tom says mac display configuration crashes probably need some user notification to avoid tons of bug reports.
  • Tom wants to fix AlphaFold 3 PAE handling so it recognizes file name and handle .npy Chai-1 format.

• Scenes
  • Piet demonstrated scenes involving atomic structures and volumes.
  • No interpolation currently.
  • Discussion of whether take_scene() method should be eliminated in favor of take_snapshot(..., flags = SCENE).

• Github Actions ChimeraX builds
  • Github actions changed name of Python package config module or eliminated old name breaking our build scripts. Zach is fixing it.
