🔥 In one test (500-frame light-sheet dataset), Ultrack reduced manual corrections by >2× ! Built to work with tools like Cellpose, Stardist, Ilastik. Open-source, napari-compatible, GPU-accelerated. awesome data from @adrianjacobo.bsky.social !

We built these tools because modern light-sheet microscopy generates massive datasets—millions of cells, terabytes of data, hours of embryonic development. 🧠 But data is only half the story. We need to track, explore, and share. That’s where Ultrack and inTRACKtive come in.

Honored that our work @czbiohub on https://t.co/Ymb0B8SRIU has been recognised! And in particular, the *disease* angle is really dear to me as it shows that the work we have done is relevant to folks that work closely with disease models. 'Be useful' is my new motto :-)

Just pushed a 'hot fix' version (2025.6.25.2) of Omega (#napari_chatgpt #OmegaAgent) that addresses some issues introduced by the ever-changing model lists from #OpenAI. https://t.co/9MiyG3Ls8U

I just asked #Claude 3.7 to make a web version of the 'Global Thermonuclear War' game from the classic #WarGames movie from the 80s. And it is not too bad!! Except for its skills at drawing continents... Game play could be more engaging too... haha. https://t.co/iFcG4PDIUW

Note: You can really think of our 'Scientist' positions as well-paid, well-resourced 'PostDocs on Steroids'. We do Science, we write papers, and we do so hyper-collaboratively.
