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

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
ND to look at Jenkins job
Consider github action to generate this

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
- https://github.com/cctbx/cctbx.github.io/issues/1
Aaron: Billy going to rebuild
ND: Remove jenkins job that was broken anyway

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

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
Work to do:
- Need to package history into MTZ, but MTZ history not the right place. Decided MTZ-appendix is the right place to put this in, but work not started yet
- Aaron has offered Yang’s skills as his work should cover this area
- Write integrate and scale history to MTZ #2924
- David to dig relevant information out

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)

reciprocalspaceship has been requested as a dependency in PR 3016
- Python-only tool which has potential to replace some iotbx functionality
- RSS functionality could be rewritten, does apparently provide useful stuff that could be leveraged later
general agreement

Marko is working on an NXmx-like format class for SerialED, where the beam position changes each image
It seems not possible to use ImageSequence for this, as it does not allow different models per image. Is this correct?
ImageSet works, but import and viewing images is much slower
Is there a long term plan to converge to just one of these classes, with all performance and feature issues fixed?
Suggestion to look at DMcD properties table
Discussion about serialization/deserialization overhead, brief discussion of using another form e.g. hdf5 or sqlite (for Experiment Lists).
Discussion of existing uses of mixin inheritance

AB had email from Aaron Finke to ask about analysis - when a stable DIALS release that supports neutrons
- DMcD working on last merges
- Both TOF and Laue being worked on
- Move this to top of next agenda so can discuss with DMcD available
AB has task to set up meeting next week, will try to involve interested parties (e.g. David’s)
