## Running and understanding the code

The code can be run by running the following script (see script for arguments and how to run):
[TAO-OW run script](https://github.com/JonathonLuiten/TrackEval/blob/master/scripts/run_tao_ow.py)

To understand the the data is being read and used, see the TAO-OW dataset class:
