* Semi-automatic tracking: Select one (or more) spot, TrackMate will find its most likely successors.
* Re-design of TrackScheme. TrackScheme is now about 40 times faster to launch, even on large dataset. By default it uses the 'simple' style, and the update of the small thumbnails can be switched on/off.
* The 'Load' button was removed from the GUI. TrackMate files can be loaded from the
''Plugins > Tracking > Load a TrackMate file '' menu item.* T/here is a new ''Plugins > Tracking > Manual tracking with TrackMate '' menu item, that launched another GUI stripped down for manual editing.
* The XML file format has changed, to include more data, and for better separability and reuse in other softwares. However, backward compatible loaders are present to ensure the loading and on-the-fly conversion with files generated by TrackMate versions above 1.2.
* Better coloring scheme. There is a unique coloring scheme shared in all views.
* The user can now define a ''depth of drawing'' display setting, that limits the number of Z-slices on which we draw the model. This is useful on very thick samples where the drawing of all the data across all Zs can become confusing.
* Minor improvement for the track display on the main view, for large models.
* Ship a MATLAB function to import in MATLAB the tracks exported by TrackMate. Check [[Using_TrackMate_with_MATLAB|this]].
* Warn the user if they feed TrackMate with a stack that has no time-points by plenty of Z-slices. This is one of the main reason we get irrelevant bug reports: By default, ImageJ considers that a multi-image file is always made of 1 time-points and many Z-slices. Whereas users mean to feed TrackMate with a movie made of several 2D planes filmed over time. We now warn the user that the dimensionality stored in the image might not be the one they expect.
* '''Fine tune multithreading'''. Before this version, TrackMate was doing multithreading during detection in the following way: We run the detection process on as many frames as we have threads, and each frame is processed using 1 thread. This is suboptimal if we have a large number of threads, but a few number of frames (e.g. 1 frame, 24 threads). This release fixes this: If we have 10 threads and 15 frames to process, we process 10 frames at once, and allocate 1 thread per frame. But if we have 10 threads and 2 frames, we process the 2 frames at once, and allocate 5 threads per frame if we can. For this to work of course, the detector must be multithreaded, which is the case with the ones we ship now.
* It is possible to manually color spots and edges. The colors attributed are saved and retrieved from XML. To use it, select a few cells in TrackScheme and right-click to make the contextual menu appear:
* There is now an action to export to [http://icy.bioimageanalysis.org/ Icy] track manager. It generates a XML file that can be opened in the [http://icy.bioimageanalysis.org/plugin/Track_Manager Icy track manager].
* Icy XML track files can be opened in TrackMate. Just point the TrackMate loader plugin to such a file, and its type will be detected and it will be opened in TrackMate. We would like to express our thanks to
[http://icy.bioimageanalysis.org/about Fabrice de Chaumont] for his help in developing these two features.
* A new action allows merging two TrackMate files into one.
* The color scale used to display colored tracks, links and spots can now be manually adjusted. In the display panel of the GUI, double click on the label "color by" and a settings window will open allowing the user to select between manual or automatic scaling. This is great to generate views that are comparable between datasets. This feature is commissioned and offered by Fumio Hayashi, Kobe University.
* When graphing spot features, only include spots from visible tracks.
* Fix a bug that prevented the XML file to be saved.
