Your friendly tracking assistant. Sniff out and fix broken tracks.


There are many fantastic tracking libraries out there (e.g. Trackastra, Ultrack, etc) but in my experience they only get ~90% of tracks right from one frame to the next...over a long movie that's a lot of broken tracks!

napari-vizsla's goal is to help you quickly fix these broken tracks. Load your tracks using the Cell-Tracking-Challenge (CTC) format (which many tracking programs can output) and get fixing!

Usage

napari-vizsla mostly consists of a set of shortcuts to quickly modify and update tracks. It will autosave your changes as you go!

Keyboard Shortcut Action
l (l)ink tracks. Select two cells, in two different timepoints, and link them into one track.
b (b)reak track. This breaks the track into two tracklets at the given time point.
h (h)ide overlay. Hides Vizsla overlay.
t hide (t)racks. Hides the track layer.
s hide (s)egmentation layer. Helpful to better see the underlying signal layer.
