In the folder RodTracker\src\RodTracker\resource\example_data\images\gp3 (and also gp4 folder) there are images 500-519 and 696 to 700.
In the folder RodTracker\src\RodTracker\resource\example_data\csv the data are for frames 500 -> 550.
I think 20 frames is good enough to get the idea of how the software works and so you could remove images 696 -> 700 and the CSV data for frames > 519.
