DIALS core meeting 2025-09-25

Previous Actions

• ND Investigate getting psana tests running on the DIALS xfel-regression testing
• ND: Move dials.diamond.ac.uk to a redirect to dials.github.io
• ND: Action: Replace dials-support link with slack link/new mailing list address (not done by ND)

Agenda

DIALS Metrics on github.io

• Can play with the power BI page
• Similar page for deposition incoming, by year / institute etc. - working out now how to integrate with the RST for dials.github.io pages.
• Discussed https://github.com/dials/dials/pull/3000
• With better title/extra newsfragment removed, not reason not to merge

cctbx.github.io

• https://github.com/cctbx/cctbx.github.io
• was built by jenkins job
• been failing for ~1year with intersphinx errors
• is this a thing that cctbx still cares about/builds elsewhere?
• ND: Make issue and tag Aaron

DIALS Office Hours

• 3pm Thursdays was what we talked about
• ND talk to JBE about running
• Make informal promise for office hours, and a slack channel that people can make known that they have a request to chat/for help about a particular topic
• JBE booked room, not sent out invites/ zoom yet - try to get done in next week.
  • Consider sending reminder to slack day before advertising
  • James to follow up with advert to non-Diamond people as it is happening already at DLS
• Graeme suggested “themes” for the office hours
• James to follow up

Metrics

• 2025-09-25 - dxtbx-side merged in, nothing yet in DIALS side to push it into the mtz history https://github.com/cctbx/dxtbx/pull/816
• Needs to be work to put in on DIALS side

iota and Prime

• Both developers moved on
• Iota: trouble configuring on recent python versions
• DIALS pulls from conda-forge directly
  • This would be a solution for XFEL
• Prime easier to drop but defer decision
  • Aaron to ask Mona what she wants to do with Prime (still on to-do)

dials.search_beam_position issues

• In discussion between Aaron and Marko
• Need to understand how to import the data to correctly represent this experiment
• Half of the raised issues resolved, the other half not sure how to address
• Now working for each detector in the experiment separately
• Non-integer results should be expected
• Aaron wants a true “per image, per image” to monitor beam centre drift, with a different detector model for each image (need to make sure this is the shape on import)
• Skip spot-free images
• 2025-09-25: Marko checked something in to do this, Aaron has yet to check

AOAOB

• Hamburg: imageset, sequences, laziness so it works on 100,000 image HDF5 files
• Want Graeme, David to be here, defer

Dials data download failures

• CI failing due to data downloads
• Does dials-data retry?
• ND has recollection that DGW was looking at this?
• Possibly more agressive retention of caches?
• Moved DGW to admin to allow to bypass failures due to incorrect download
• Possibly: Need to check status code on file download?

AOB

Pycbf missing from cbflib repository

• Removed because regenerated
• Discussed multiple options, including:
  • Putting back in cbflib
  • Using cbflib from conda-forge
  • Just pinning
