* The CSV handlig is for the moment hard-coded to fit the current project due to a very specific file structure and respective naming convention. * The CSV handlig is for the moment hard-coded to fit the current project due to a very specific file structure and respective naming convention.

| Handle_emg_data.py: - Data_container - CSV_handler - NN_handler | Handles, manipulates, and stores data for analysis. - Data_container is a class that describes the data for each subject in the experiment. Use __init__. - CSV_handler takes data from CSV files and places it in Data_container for each subject. Use load_data() to load csv data into data containers and add the containers to the CSV_handler's 'data_container_dict', indexed by subject number. Use get_data() to retrieve specific data. - NN_handler prepares data for further analysis in Neural Networks. This class has storage for this data and/or can save it to a json file. |
