+## Agenda
+
+### 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
+- MTZ Appendix: Some controversy
+    - Phenix/DIALS not included in discussions
+    - Fundamental technological issues
+        - Mixing MTZ/CIF
+- Gemmi supports
+
+### 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
+- Probably table for new year
+
+### 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
+
+### APS Workshop
+
+- GW had conversation about expanding workshop scope. Was half-day, thought maybe a full day - scope expanded to e.g. serial processing 
+- May 4th-8th 2026 two half-days of DIALS workshop probably
+- Some travel funding available, potentially from outside US
+
+### MCD outlier rejection
+
+- Discussion about https://github.com/dials/dials/pull/2676, ND connection degraded and had to leave
+- Was merged in, AB not 100% convinced but could be useful in some cases.
+
+### Tweak to LICENSE
+- See https://github.com/dials/dials/issues/3056. Came up regarding copyright assertion in PR from Olex2
+
+## AOB
+
+- General offer from Dan Paley for DIALS West to take over any release process work that could be supported
+- Note that after new Optuna dependency was added this caused scrambling on DIALS west side, as some separate dependency lists maintained
+- PSAna2 PRs
+    - https://github.com/cctbx/dxtbx/pull/860
+    - https://github.com/dials/dials/pull/3038
+    - DIALS East to have a look at in next week
