It privileges tracking schemes where the segmentation step is decoupled from the particle-linking step.
Code activation time lapse tool series#
The tracking process is divided in a series of steps, through which you will be guided thanks to a wizard-like GUI. TrackMate aims at offering a generic solution that works out of the box, through a simple and sensible user interface. Its development focuses on achieving two concomitant goals: For users TrackMate can compute numerical features for each spot, given its coordinates, a radius and its shape.įor instance, the mean, max, min and median intensity will be computed, as well as the estimated radius and orientation for each spot, allowing to follow how these feature evolves over time for one object. Cell-like objects would be objects for which we can retrieve the shape and use it for subsequent analysis.Examples include sub-resolution fluorescent spots, labelled traffic vesicles, nuclei or cells imaged at low resolution. Spots are typically bright objects over a dark background for which the object contour shape is not important, but for which the main information can be extracted from the X,Y,Z coordinates over time.TrackMate can deal with spot-like objects or cell-like objects. These tracks can then be either visualized or yield further analysis results such as velocity, total displacement, diffusion characteristics, division events, etc… Each object is detected or segmented in multiple frames and its trajectory is reconstructed by assigning it an identity over these frames, in the shape of a track. SPT is an image analysis challenge where the goal is to segment some objects and follow them over time. TrackMate provides the tools to perform single particle tracking (SPT) typically in the context of microscopy. This is the resulting segmentation on a Drosophila melanogaster embryo: The idea is to tell TrackMate “this is not a 3D image but a 2D+T image that you will track”.įor instance you could use cellpose on the individual 2D slice to segment sections of the object, then merging the multiple 2D contours in a single 3D object. They work especially well in 2D but we can also use them to segment 3D objects with TrackMate. TrackMate ships and integrates several nice Deep-Learning based and Machine-Learning based segmentation algorithms. Segmenting objects in 3D with a slice-by-slice approach The track follows the lineage from cell AB to ABaraapap.

Code activation time lapse tool movie#
Generating movies that follow a single cell over timeĪ movie following one cell of a C.elegans embryo tracked over 3 hours, as it divides. For 2D images, TrackMate can measure the morphological features of the objects it tracks. The bottom graphs display the cell area and circularity for the cell highlighted in green in the above lineage. The lineage follows the growth of a Nesseiria meningitidis. Measuring morohpological features over timeįollowing cell morphology over several divisions within a lineage. These measurements can be browsed, exported and plotted from within the user interface. TrackMate performs a number of measurements on the objects it tracks.

TrackMate can be set to detect and deal with gap-closing events, splitting events and merging events. Tracks with fusion, split and bridging gap events. Tracks with fusion, split and bridging gap events (However, the object contour is displayed only for 2D images.) TrackMate works indifferently in 2D or 3D.īelow is a movie showing the first 2 hours of a C.elegans embryo development, followed in 3D over time using TrackMate (strain: AZ212). Starting with version 7, TrackMate can detect, store and exploit the object contours in 2D.Īlso, TrackMate integrates state-of-the-art segmentation algorithms, such as ilastik, MorphoLibJ, StarDist, and Weka.īelow you can see migrating cells tracked with the StarDist detector implemented in TrackMate.

Using state-of-the-art segmentation algorithm TrackMate also has a component to display and annotate cell lineages: TrackScheme. TrackMate is distributed in Fiji, integrates well with ImageJ and Fiji tools, and does not require a complex installation procedure.
