- Meeting Minutes
- diSPIM update
- Team has been running Paulina's samples
- 6 datasets acquired (same volume; 12 TB)
- **Current bottleneck**: downstream processing of stitching
- Adam will be sending data to another group to run processing using Matlab as a POC
- Acquire software is not crashing on acquisitions
- Pixel size metadata
- [ ] Nathan : add parameters around pixel size
- pixel size is optional in the API
- TIFF spec requires pixel size
- dimension sequence metadata
- ImageJ has this, however, z and t planes do get swapped/interchanged
- This is relevant in both ZAR and TIFF because the user needs to specify context for dimension planes (z & t)
- General metadata approach
- AI team to provide requirements
- Nathan to fit to those req. as needed
- Adam receiving template in coming week
- Micah GUI demo
- 3D map depecting acquisition location in relation
- Zarr MVP demo
- Alan got a Zarr MVP working!
- Zarr folders are created; Single Zarr chunk file at ~10GB in example shown
- Takes napari a while to load
- New fix will replace '.' separators with '-'
- New fix will need to implement chunking during acquisition

- Action Items
- [ ] Nathan : add parameters around pixel size
- AIND-CZI/Biohub data sharing
- [ ] David needs to get info back to Adam
- [ ] Need to revisit language in CRA re: data sharing (esp. w/ hosting on BioHub)
