- IDR
- Will: adapting [check_pixels.py](https://github.com/IDR/idr-utils/pull/55#issuecomment-1915051356) script, running in parallel to try and reproduce issues we've seen from web. getPlane() doesn't cause issues but renderImage() does. Need to look into stack traces.

## AOB

(5 min. max; tech. Discussion should be highlighted to relevant people and rescheduled)

## Main Topic

(20-25 minutes plus 15 minutes questions max)

- Erin: Tissue clearing workshop last week - 100 attendees.
- Presented our Webknosses work
- Users typically use desktop apps - remote Desktop etc
- Advantages of web browser access
- Most viewers aren't 3D
- Users are familiar with Webknosses
- Webknosses: orthogonal views and volume view
- OMERO.script tells Webknosses where the s3 NGFF data is and gets a URL to open Webknosses.
- Webknosses server provides auth etc to access s3 but web viewer does consume zarr data.
- 3D chunk data 32 x 32 x 32 doesn't open in PathViewer
- OMERO.script is very fast & light - could be done with Open-with plugin instead of a script?
