# Selection test experiments

The folder `experiments/selection` contains a directory skeleton for processing items for the various selection test experiments including the config files. E.g. for processing the items for BS1534-1a, the input files need to be put into `experiments/selection/BS1534-1a/proc_input`, then execute `python3 -m ivas_processing_scripts experiments/selection/BS1534-1a/config/BS1534-1a.yml`. The output files will be in `experiments/selection/BS1534-1a/proc_output`, in subfolders per conditions.

Note that for P800 experiments, there are separate configs per category as different background noises need to be specified. Thus, there are several config files with `-catX` suffix available. The background noise files need to be put into `experiments/selection/P800-X/background_noise`. To generate all categories, there is a convenience script `create_items_p800.py` in the repository root folder.
