If your recording contains keystroke markers, a JSON file will also be exported. This JSON file contains the descriptions of the keystroke markers used and their corresponding values in the EDF and CSV files.

A Baseline JSON file is created when baseline recording is enabled. The baseline markers and their corresponding values are:

  • Eyes Opened Start : 1

  • Eyes Opened End: 2

  • Eyes Closed Start: 3

  • Eyes Closed End: 4

In case of EPOC Flex, a separate JSON file is created that outputs the mapping for channel names and sensor positions for the selected session. For e.g.:
