Details

The function performs the following steps:

  1. Reads the file header to check for the presence of a "Device Type" field.

  2. If the device type contains the string "GENEActiv", the device is identified as a GENEActiv device.

  3. If the "Device Type" field is not found, it checks for a MATRIX device by validating a specific header value ("MDTC").

  4. If neither device type is detected, the function returns "not_recognised".
