Nouvelle vidéo ! FRONDE GRAVITATIONNELLE, SINGULARITÉS & POINTS DE LAGRANGE.

On s’intéresse à quelques subtilités de la gravité newtonienne dans l’espace, et notamment le fait singulier qu’elle permet de se rendre à l’infini…en un temps fini !

Ca se passe par ici:

BoneJ @bonej.org · 10d
📢 Release alert!

This one lets *all* Intel GPUs use BoneJ+ 🤖

If you have an Intel Iris Xe, UHD or Arc, support is more robust.

Background:
Intel omitted 64-bit floating point precision (double) in their GPUs since c. 2020: this update uses the universally-supported single-precision float type.

Happy holidays from an amazing team.

#Mastodon, the Command Center for Large-Scale Lineage-Tracing Microscopy Datasets, is finally heading for publication (well, let's see). To #cite or not to cite shall no longer be the question 🙃, because the #preprint. Software is available in every #Fiji near you.

🚀⭐️ Trackastra update 🚀⭐️

We just released a new model that uses pre-trained image features from Meta’s SAM2 model.

This improves performance on many datasets, most notably for bacteria tracking.

To give it a try, simply install with the new optional dep `etultra` github.com/weigertlab/t...

Yep exactly.
SAMJ is based on the preview off a brand new technology called appose that does everything transparently (download etc)
TrackMate 9 will be based on that

Summoning @ctrue.bsky.social

Got done by the copy / pasting of animated gifs again:

I am very grateful to my colleagues in the F-BIAS team that helped me find and address edge cases for the conda autodetection.

Enjoy!

etc. They are described and documented here:

New editing modes for the TrackMate segmentation editor

In the v8.1 we introduce editing modes for the segmentation editor of TrackMate. These modes leverage the capabilities of Labkit to facilitate the edition of segmentation masks.

Second, there is a better TrackMate conda configuration tool, that tries to autodetect where conda is installed on users system, and try to input sensible values in the configuration plugin.

This part has been written with the help of the Claude LLM to help me get the many edge cases right.

First, Python tools are now ran using conda run everywhere. This should fix most of the “0 spots found” bug we see occuring.

Additionally, the way we run Python tools installed in conda environment is still too brittle, relying on conda activate or inferred path to python executables. This new version aims at making all of this more robust and easy to use.

First, we reworked the conda configuration and the way conda tools are run in TrackMate.

It seems that there are almost as many conda installations as users in biology, and the difficulty of finding where conda is installed and what to input proves to be a hurdle to many TrackMate users.

The new version of TrackMate, the v8.1 has just been released. It builds upon the recent v8, linked below, and offers two main improvements 👇
We just released a new major version of TrackMate (v8), the cell and organelle tracking plugin of Fiji.

It ships many new features, detailed below, but that are articulated around the following:

Here is a presentation by Samuel Panze on ManVR3D (Manfred), PhD student extraordinaire in the unit of Ulrik Gunther, and that built an eye tracker, VR based tool for tracking cells.

ManVR3D uses Mastodon as the tracking backbone 🎉
