#Ultrack
It takes Cell-Tracking-Challenge (CTC) output from awesome tracking programs like Trackastra (by @bengallusser.bsky.social) or Ultrack (by @jookuma.bsky.social) & autosaves to CTC output as you go!

Made possible by the great @napari.org ecosystem and tracksdata from @loicaroyer.bsky.social's lab.

Amazing work! Happy to see Ultrack used here 😄!

Thanks! The cell tracking was done using the software package Ultrack from @jookuma.bsky.social et al, 2025 in @loicaroyer.bsky.social lab!

How do you track thousands of cells in complex systems, in 3D & over time? We are launching a Kaggle challenge to push the frontier of AI-powered cell tracking, building on advances like Ultrack & the DaXi lightsheet microscope from the @loicaroyer.bsky.social lab.

This is the problem behind Zebrahub (the Biohub's "Google Earth" of zebrafish development) and Ultrack 📄, our method in Nature Methods 2025 that topped the Cell Tracking Challenge on dense 3D embryos. Now it's your turn to push the state of the art!

Second speaker is @teunhuijben.bsky.social from @loicaroyer.bsky.social group at @czbiohub.bsky.social #CBIAS2025
Tracking is hard because segmentation is hard, especially in whole zebra fish embryos: Ultrack can help github.com/royerlab/ult...

Happy to be in London for #CBIAS2025! Looking forward to two days of image analysis, and presenting #inTRACKtive and #Ultrack tomorrow 🔬😊
And we’re off. #CBIAS2025 6th Edition, first outside of the Crick but impressed by the localities at @wellcomecollection.bsky.social
@david-j-barry.bsky.social welcoming the community

Kudos @ritastrack.bsky.social for the great years at NMeth!
And congrats to my former colleague Jordao Bragantini for ultrack (and the well deserved cover 🎉) and @teunhuijben.bsky.social for inTRACKtive.
Glad I could contribute to these two wonderful endeavors. GO team @loicaroyer.bsky.social! 🧪🔬
I won't talk about NMeth @natmethods.nature.com forever (probably), but I do want to brag a bit about the November focus issue on cell segmentation and tracking, which is many ways is my last hurrah (and final editorial) for the journal. I am so proud of these papers!! www.nature.com/nmeth/volume...
