Trumouse Pro combines 144-channel RFID identity recognition with automated video analysis to track up to 20 individually identified mice simultaneously, in a 1.2m x 1.2m arena.
Estimates for one study comparing wild-type and knockout mice on open field, circadian rhythm, dominance and social behaviour, against running the usual separate tests. Cost counts staff time at US$25 an hour and mice at US$100 each, including housing; equipment and tags are not included.
Up to 20 mice in one arena, so wild-type and knockout groups of ten run together in one batch. Recording goes on for weeks to months; what is left by hand is tagging, cleaning, a daily check and reviewing the results.
Identity, tracks, chases, time in each region and rankings come out on the results page, and everything exports as CSV. For anything else, ask the Agent in plain language and it makes the chart.
Every mouse is identified while the group lives together, so you can see who ranks first, who stays with whom and how the group changes over weeks.
The overhead camera follows every mouse. 144 RFID readers under the floor read each mouse's implanted tag whenever it passes over one. Trumouse joins the two, so a trajectory keeps its identity through huddles, burrowing and crossed paths.
One real recording, straight from the results page. Everything exports as CSV: per-second trajectories, events, regions and environment.
Trumouse counts every chase between every pair in the home arena and ranks the group with David's Score, Elo ratings and Landau's linearity index.
