Discussion

• Talk on ChimeraX web services implementation by Zach
  • Zach explained new REST web services method for replacing SOAP/Opal.
  • Discussed how input parameters for job are passed.
  • Discussed how job return values are packaged (e.g. multiple files).
  • Discussed how job progress reports might work.
  • Scooter would like existing ChimeraX web services using this long before ChimeraX 1.4 release (May 2022?)
  • BLAST is using it.
  • Next is Modeller, Zach will get it done by 2 weeks from now and present.
  • Then multiple sequence alignment (clustal) added using Opal by Eric 2 weeks ago.
  • Eric will try to implement REST seq alignment after Zach converts Modeller.
  • Another service to convert is AlphaFold BLAT search.
  • And a more complex case to try later is AlphaFold prediction on Wynton.

• Qt 6 ChimeraX on download page
  • Greg hopes to havel Qt 6 tech preview on download page tomorrow.
  • Tom has been using it 4 weeks without problems.
  • Tom wants it in circulation to see if many Qt 5 crashes are fixed, or workarounds needed.
  • Greg notes new Fedora Linux versions work with Qt 6 but not Qt 5.
  • Greg has setup tech preview support on download page for future uses.
    • Runs script at start of build to patch files or do other setup.
    • Flag indicates whether to add it to download page.
    • Can edit download page to explain what is new in a particular tech preview.

• Redesign of client Task / Job classes

  • Discussion of drawbacks of inheriting from dict
    • Allows too much access to dict methods.
    • Can confuse session saving seeing an instance as a basic type.
