🚨Open call to the Cell Tracking crowd out there🚨! Loïc's team at @biohub.org opened our Kaggle Challenge for 3D cell tracking, with $60k of prize money💰. Spread the news, delve into our gigabytes of imaging (zarr3) and cell tracking (geff) data of developing zebrafish embryos, and start tracking 🤩

From v0.2.0 MissAlignment now has an inference mode where you can apply the trained models from one dataset to a new dataset to skip training time. I haven't tested it extensively, so double check if the results look decent 😉 The program calls changed slightly, see here: github.com/warpem/miss-...

Inspired by Utz, I ported the old Briggs lab tools to ChimeraX in a single bundle named Geopickr, with some extra utilities (geopicking on morphometrics surfaces!). I've submitted it to the toolshed, but in the meantime: github.com/baradlab/Geo...

Cryo-ET gives unparalleled views of cellular structures, but targeted sample preparation by cryo-FIB milling has been a constraint. No longer! A new workflow yields close to 100% targeting success for centrioles & other small structures. Read the preprint ⤵️ www.biorxiv.org/content/10.6...

In a series of 3 papers and preprints, we’re thrilled to share with you the working laser phase plate. In collaboration with research led by Holger Müller at UC Berkeley, this is a huge innovation in imaging to make small and faint objects inside cells visible. bit.ly/4vK9LVn

Hey #teamtomo, if you often find yourself using the excellent membrain-seg from @lorenzlamm.bsky.social et al., you might find my napari plugin "napari-segselect" useful. Let's say your tomogram contains the edges of two bacterial cells, each with a membrane and cell wall:
