#PARTICLE TRACKER IMAGEJ HOW TO#
The second shows how to process a 4 D image stack showing the time-lapse growth of Drosophila cells in an embryo.
#PARTICLE TRACKER IMAGEJ SOFTWARE#
The first processes synthetic data to show all the software functionalities. This tool has been successfully used in three applicative examples. The Visual4DTracker toolbox permits the users to visualize and save all the generated results through a user-friendly graphical user interface. Furthermore, it allows users to proof-read and to evaluate the traces with respect to a given gold standard. It is a MATLAB package implementing several useful functionalities to navigate, analyse and proof-read the track of each particle detected in any \(3D+t\) stack. This manuscript introduces our new freely downloadable toolbox, the Visual4DTracker. To extract useful information there is the need to extract spatial and temporal data on the particles that are in the images, but particle tracking and feature extraction need some kind of assistance. This operation may be monitored by generating a VRML file of the 3D+time dataset (Figure 4) which can be viewed in any web browser equipped with the appropriate plug-in (see documentation for more details).Biological phenomena usually evolves over time and recent advances in high-throughput microscopy have made possible to collect multiple 3 D images over time, generating \(3D+t\) (or 4 D) datasets.

The Manual Tracking module was improved to allow a simple retrieval of z coordinates. The Manual Tracking module has display capacities aiming to provide either a synthetic vision of the tracked points and/or their paths (figure 3, top), or an overlay of one of the synthetic representations and the original image (figure 3, bottom). Á Parameters: this section contains all required calibration values and drawing settings. Several displays are available: each button's function is illustrated in the following section Á Drawing: this section deals with the ways to get a visual representation of the coordinates recorded in the results table. Á Directionality: retrieves information on whether the movement is retrograde or anterograde. Á Centring correction: helps the user to point the right pixel. O "Delete all tracks" is used to clean up the results table. This choice should be validated by clicking on the "Delete track n¡" button. O By selecting the number in the list next to the "Delete track n¡" button, the user is allowed to erase one track from the result table. O "End track" button should be used to stop the tracking procedure in case the structure disappeared from the image. O "Delete last point" is used to erase the last recorded coordinates. After each mouse click, the following image of the temporal stack is activated until the last image is reached or the "End track" button is pressed. O The tracking is done by clicking on the structure on the image. O To start recording one track, the user has to click on "add track". Note: as the first velocity value can't be calculated (first tracked frame where time interval equals zero), its first displayed value will be -1, as in most of the commercial software. This plug-in provides a way to retrieve in a table (figure 1) XY and XYZ coordinates as well as velocity, distance covered between two frames and intensity of the selected pixel or volume, by simply clicking on the structure of interest. This plug-in allows the user to quantify movement of objects between frames of a temporal stack, in 2D and 3D.
