Column descriptions
- group_session
- Group session ID
- task
- Task ID.
- station
- The iMac that the participant was stationed at.
- participant
- Participant ID. A participant ID of -1 indicates an unknown participant. All rows that do not have values for the `task` column will have their participant ID set to -1. In the future, we will label some of these inter/pre/post task rows with the correct participant ID.
- timestamp_unix
- The Unix timestamp of the event.
- timestamp_iso8601
- The ISO-8601 timestamp of the event.
- filename
- Name of the screenshot file.
- timestamp_origin
- The source of the timestamp. The priority is precision-driven. LSL time are used if available, otherwise, creation time is used if available. Modification time is used as last resort.
