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.
