- [ ] **JBE**: H5 on-disk experiment: review practicalities of using this & welcome people looking at James's work above. round trip example files could be useful - exists in dials.export.
## Agenda

### JBE Demos
- Previously [[prev](https://dials.github.io/kb/core/2024-04-04)]:
- Draft PR https://github.com/dials/dials/pull/2567
- GW suggested making a special release in order to test this changeset at DLS (in new year).
- Wait until PR notes addressed, then build this as a test release for wider consumption
- Not been touched much since NY
- Keeps coming up as something that would be useful
- James has rebased this, updated tests, Rick and Kevin feel OK with this => need to pick up some PR comments

- Aaron points to [notes](https://github.com/cctbx/cctbx_project/tree/master/xfel/conda_envs)
- Previous Actions: Still relevant?
- **AB**: Run this against Xfel-regression tests: AB pls can you run this James?
- ~~**ND**: Make test release using these branches~~
- Few more issues outstanding
- 3.19 out now so good time to merge testing - providing xfel-regression works
- JBE not available today, defer to next meeting
