+## Previous Actions
 
-This is a future meeting, please see the WIP agenda at [hackmd.io](https://hackmd.io/1TxI3G_DSFulIhqkTBpJSQ)
+- [ ] **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
 
+## Agenda
+
+### DIALS Metrics on github.io
+- Can play with the [power BI page](https://app.powerbi.com/view?r=eyJrIjoiZWQxYzQ3OGUtZGIwYS00NDZmLTk1YjctNDU1YmViNTI5ZDNjIiwidCI6IjM5NjU3M2NiLWYzNzgtNGI2OC05YmM4LTE1NzU1YzBjNTFmMyIsImMiOjZ9)
+- 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
+
+### 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
+    - https://github.com/cctbx/cctbx.github.io/issues/1
+- Aaron: Billy going to rebuild
+- ND: Remove jenkins job that was broken anyway
+
+
+### 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
+- 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 ](https://github.com/dials/dials/pull/2924)
+    - David to dig relevant information out
+
+### 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)
+
+### Additional dependencies
+- `reciprocalspaceship` has been requested as a dependency in [PR 3016](https://github.com/dials/dials/pull/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
+
+
+### AOAOB
+- Hamburg: imageset, sequences, laziness so it works on 100,000 image HDF5 files
+- Did some work in a branch to get stills_process to use imagesequences
+- Nick did some work to eliminate need for check_format
+- All of this is in branches that have not been revisited
+- Discussion about still goniometer dogma
+
+### ImageSequence vs ImageSet
+- 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
+
+
+### 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?
+- Discussion: Worth hosting on LBL?
+
+
+## AOB
+
+### Neutrons
+
+- 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)
