ethoscope tracking database columns "is inferred" and "has interacted"

[rjs360]

Hi all,
Finished my first few ethoscope tracking experiments with sleep deprivator units (https://giorgiogilestro.notion.site/The-new-Modular-SD-Device-05bbe90b6ee04b8aa439165f69d62de8) today (yay!), and notice two columns in the .db files (reading them in "DB Broswer for SQLite" currently) named "is inferred" and "has interacted" which either take "0" or "1" values. Can someone tell me what these two columns indicate exactly? Do "has interacted" of "1" refer to sleep deprivator motor action? Thanks for any shared insight - Ruud
