Do you love quantifying animal behavior as much as we do? We have just the tool for you! Presenting #OCTRON - a pipeline that helps you create rich annotation data and enables training of custom segmentation models. Have a look, particularly if you work with non-model / invertebrate organisms!

OCTRON stands on the shoulders of giants. We make use of #SAM2 (meta), #YOLO11 (ultralytics) and some of THE best multi-object trackers out there #BoxMOT. For rapid data access we use python-zarr (>3.1).
We couldn’t have done it without the super supportive community surrounding @napari.org.

New video: more examples showing deep learning segmentation failure modes—and how to detect them with Napari. I show how Napari’s layer system compares images, ground truth, and results, and how Appose enables comparison across incompatible DL packages. www.youtube.com/watch?v=c369...
Using Appose with Pixi and Napari for reproducible deep learning segmentation workflows.

And that’s a wrap for the @cbias.bsky.social napari workshop as well. Two days of learning, working collaboratively and finished off with a presentation from each of five project groups detailing the progress they made. Organised by Rocco D’Antuono, @giuliapaci.bsky.social and yours truly

I wrote my first proper post on LinkedIn today. It was cheesy, bit of a weird thing to do.

Bottom line is I'm still buzzing from spending two days playing with napari sourounded by kind microscopy nerds at the #CBIAS2025 Napari Workshop.

Happy to finally share micromorph with everyone!
If you are interested in performing morphological measurements of bacteria, and like using Python and Napari then this is for you!

You can read about it in our preprint, and find the code on our Github repo, PyPi or directly from the napari hub!

Hi Fans of Feedback Microscopy,

what would you do when you have access to the pixel stream from @zeiss-microscopy.bsky.social inside @napari.org?

Btw, it works as well in Fiji&ImageJ :-)

Sidenote: Experiments started from "outside" do not update the ZEN UI. But they are executed by ZENservice.

I'd only dabbled with napari, but needed to use it for a paper we're writing. This is a quick post about getting started: from installation to a folder full of thousands of processed images, with gotchas along the way.
