Broken gif in original post 😱...better look at the new feature of the @napari.org-clusters-plotter here 👇

Finally some feature processing: I personally find getting a feeling for some #unsupervised #ML parameters hard, e.g., in dimensionality reduction/ #clustering.
Click yourself through the parameters and see what happens interactively!

Needless to say, the algorithms are extensible⬆️📈

Shapes 📐: The new clusters-plotter automatically assigns a fitting colormap to "categorical" features, which is neat when visualizing, e.g. skan (skeleton-analysis.org) #skeletons: Skeleton ids are then automatically assigned fitting colors - no need for manual selections!

With a little help from @stefanhahmann.bsky.social , tracking data is now supported, too. Goes to show the frame-highlighting for #timelapse ⌛data in the new version:

More supported layers: A major upgrade allows to interact with all sorts of @napari.org layer types: Labels🏷️, Points✴️, Vectors🏹, Shapes🔻, Tracks🔀 and even Surfaces⚫!
Particularly cool about Surfaces: @mazoc.bsky.social's histogram view leaves unselected areas transparent!

FINALLY just released the @napari.org clusters-plotter 0.9.0 🤗 pypi.org/project/napa... The latest version comes with a complete overhaul of the entire codebase to make #microscopy data introspection and browsing even more accessible, intuitive and versatile! #bioimaging

Let's have a look 👇🧪💻🔬

Secondly, which I think is very cool: You can now draw annotations in napari and upload them to OMERO. Hopefully this makes annotating large datasets a lot less painful! 💥

(Nevermind my shonky drawing - don't annotate like me 😄)

Looking forward to feedback/bug reports: github.com/tlambert03/n...

New release: napari-omero 0.5.0 😀@openmicroscopy.org @napari.org thanks to some big contributions from @psobolewskiphd.bsky.social , @will-j-moore.bsky.social and of course @talley.codes. Some features in spotlight 👇

First: napari-omero now supports lazy loading of image pyramids from OMERO🔺:

Some new additions for the upcoming @napari.org clusters-plotter version 👉0.9.0 around the corner! Powered by some work from @mazoc.bsky.social, it casually turns into a pretty neat tool for feature map creation 😀

Fancy new #3dprinting toy 🤩 Maybe I'll start printing all my collaborators some of their data for segmentation tasks as giveaways 🤗
