We had an amazing OME-NGFF hackathon last week, Wednesday to Friday, following the inspiring OME-NGFF symposium. What a fantastic week! It’s hard to describe how motivating it is to be surrounded by so many talented, curious & friendly people who care deeply about open, FAIR bioimaging data.

I am still digesting all the info from the OME-NGFF hackathon last week.

So I decided to make a little UI for some of the code created there (just to play around), which one can easily show to interested colleagues 😜.

CZI --> OME-ZARR with some options ...

By far not perfect but still fun!

It's been great to present OME-Zarrs & Fractal for interoperable bioimage analysis at the 2025 @cytodata.bsky.social conference in Berlin today. Thanks a lot to the organizers & especially Christopher Schmied for having us!

Go read Joel's thread on the hackathon last week in Zürich! If you have any level of interest in OME-NGFF, there are so many exciting things happening. I had a great time meeting some of my favorite people in the world - It was equal parts rewarding, fun and exhausting 🙃️
