CeTrAn is a R script to analyse trajectory data, at the moment only data obtained from Buritrack a tracker designed for fruit flies running in the Buridan assay. see also www.buridan.sourceforge.net.
The progam used to work with rgg (then it needs java 6 to run correctly), but was recently moved to shiny (not tested yet). You need to install Rstudio and open the server.r file and click the run app button.
To run the latest version, you can also open R and run:
library(shiny)
shiny::runGitHub('CeTrAn', 'jcolomb')
But this will download the complete app, including the test data.
