The file formats used by CapnoBase are comma separated values (.csv) and Matlab (.mat) files.
Signals, metadata, and annotations are stored in separate files.
The coding of files is as follows:
e.g. A66_meta.cvs or 100B_sig.mat
The online CapnoBase repository allows files to be downloaded in a compressed file format (.zip).
In Matlab files, data is generally stored in a structured format.
In csv files, the structure fields are replaced by unique row headers.
E.g. If the matlab stucture is meta.sensor.co2.manufacturer, the corresponding csv row header would be meta_sensor_co2_manufacturer
