This page applies to trackR("classic"), trackR("quanta"), and trackR("tracktor").


If you made it all the way here, you are almost ready to start the tracking itself. The Tracking tab (shown below) contains a couple of control sliders to consider before you can finally get the data you have been patiently waiting for.



  • Look back controls how many past frames the tracking algorithm should take into account to associate each blob to a track. This is a useful parameter to take into account if, for instance, the objects tend to disappear for a few frames from time to time.
  • Maximum distance (pixels) controls the maximum distance in pixels that a blob can move between two frames to be still considered as belonging to the same track.
  • Display tracks (slower) controls whether the video with the overlaid tracks is played as the tracking is happening. If it is, this will slow down the tracking process, but this can be used to check that the tracking is working well when looking for the right set of parameters.

Once all is set, you can finally click on the Start tracking button and let trackR works its magic. The data will be saved as a CSV file in the same folder as the video file.
