Discussion

• ChimeraX 1.6 release
  • mmCIF out of memory bug reports
    • There have been 3 mmCIF out of memory bug reports with 1.6 release candidates, possibly just 2 different users.
    • There were 3 older mmCIF out of memory reports.
    • All reports on Windows.
    • The mmCIF files with pdb identifiers are not large
  • Tom Ferrin observed a 3 minute hang on ChimeraX release candidate startup with 3 timeout messages logged to cxservices checking for ChimeraX updates. Greg will look into it.

• Chimera release
  • Ready to release. Plan is to release on Thursday. Greg will do it.
  • Eric made a fix to session exporter last week.
  • Wynton update to Rocky 8 is being postponed until Fall, but we still will update plato to Rocky 8, possibly in the May 1 day service outage.

• Wynton and BeeGFS
  • BeeGFS will have a point release in May 7.2.5 to 7.2.9.
  • BeeGFS 7.3.3 fixes a known hang on Wynton but will not be updated until Fall.

• CGL email
  • CGL email will use ProofPoint filtering in coming months.
  • Should get better spam filtering.
  • Still looking at how to examine rejected email since ProofPoint sometimes has marked legitimate email as spam.

• SVN web service
  • We have an SVN web service, original for Chimera running.
  • IT not happy about it since it is so old.
  • Chimera source distribution switched to tar file many months ago.
  • Can shut down svn web service.

• NIAID new contract
  • Still have not heard when new NIAID contract will start. Waiting for GuideHouse.
  • Scooter will talk to Nada Midani soon if we receive no info.
  • Uncertain whether we have Thursday NIAID meeting. Phil Cruz did not respond to suggestion to reschedule last week's meeting to this week.

• Chimera source code on github
  • Greg suggested putting Chimera source code on github.
  • Scooter does not think we should put effort into this.
  • Greg says he is putting MidasPlus source code in github as side project.
