Not going to be in Cracow for the big event so had to make do with a small impromptu @napari.org x @openmicroscopy.org #omezarr Hackathon in Bern 🔬🇨🇭 @m-albert.bsky.social @guiwitz.bsky.social

napari is such an incredible piece of scientific software! 🚀 And it's not just for visualizing static data. I've been using it for the past 6 months to drive a @verasonicsinc.bsky.social ultrasound system for #fUSI, and get a nice GUI for sequence control and live visualization! 🤩

Struggling for something to do in a TWO DAY gap without ⚽? How about trying our pre-release of napari 0.8.0? napari.org/dev/release/... Of note, this release drops Py3.10 support and deprecates PyQt5 in favor of PyQt6. It also adds some neat new features and improvements! See below: 👇

Drawing regions of interest has been among our most-requested features, and a long time in the making. Building it on top of @napari.org was fun. Drawing and editing shapes is such a joy!

SWC/GCNU Neuroinformatics Unit@neuroinformatics.dev · 3mo ago

Movement v0.16.0 released! This version now comes with the ability to draw, save, and load Regions of Interest in the GUI, and load_dataset can now automatically detect the source software. See the release notes for more info and a full list of changes: github.com/neuroinforma...

Woohoo, copick is out! Access to massive amounts of CryoET data, MCP for agentic, plus a @napari.org interface! We even used it when hosting the CZII CryoET Kaggle competition: www.kaggle.com/competitions... when we needed to support a large collaborative annotation event with humans + ML models.

Utz Ermel@uermel.bsky.social · 4mo ago

Excited to share our paper about copick, a dataset API and toolkit for collaborative annotation and analysis of #cryoET data! Whether you're picking particles or curating segmentations, copick reduces friction and brings #OME-Zarr to cryoET without breaking pipelines. 🧵👇 doi.org/10.1002/pro.70578

Since @napari.org just released 0.7.0 I also checked if my to little plugins still work and released new versions with some small updates. pypi.org/project/napa... pypi.org/project/napa...

I used @napari.org (specifically the animation tool originally by @guiwitz.bsky.social) to project the time series into the Z dimension and cellpose (@computingnature.bsky.social) to segment the cells, I can send you a code template if you'd like?

Friday fun with: pyapp-kit.github.io/ndv/latest/ pymmcore-plus.github.io/ome-writers/ github.com/zeiss-micros... - run an acquisition in ZEN - capture the pixel stream via ZEN API - write it directly to an OME-ZARR using ome-writers - display it in the NDV viewer. Also works with @napari.org 😉

I'm happy to present our new tool, EpiCure, a napari plugin to ease correction of segmentation and tracking of epithelia movies, developed in @devstempasteur.bsky.social

napari 0.7.0 is available now! 🚀🎉 It's a BIG release so read the full release notes, with highlights: napari.org/stable/relea... We want to thank everyone who has worked incredibly hard on this release including our 11 new brilliant contributors 🤩 and the community for their support and feedback!
