Discussion Notes

• PySide in next ChimeraX release?
  • Eric mentions many ChimeraX crashes related to PySide have been reported and we may use PyQt for the next release.
  • We don't need to renew the PyQt license to use the PyQt 6.10 in the next ChimeraX (June 2026) because that PyQt version was released during our current PyQt license period.
  • Scooter suggests checking PySide bug tracking to see if any of our crashes have been reported.
  • TomG suggest we can try PySide 6.10.3 when it comes out next week. Currently we are at 6.10.1.
  • We are not able to reproduce any of the PySide crashes.

• PDBe wants public DockerHub ChimeraX
  • PDBe wants to use ChimeraX addh to add hydrogens in a structure processing workflow using NextFlow.
  • They say NextFlow needs to get a Docker image of ChimeraX from DockerHub.
  • We told them that circumvents our ChimeraX license.
  • They said they will try other software to add hydrogens.
  • Eric suggests we could distribute a DockerHub ChimeraX without Qt libraries.
  • Greg will try to make a ChimeraX docker image.

• ChimeraX metal graphics pull request
  • Tom Ferrin asked about large ChimeraX pull request to replace ChimeraX graphics from Mitch Murphy.
  • Discussed that that is no maintainable.
  • Zach closed the pull request explaining such a change would not be maintainable.
