This repository contains video data used both for the development of the TRex (https://trex.run/) tracking software and for teaching its use. The filenames use the convention project_YYYYMMDD_N Where: - project stands for the project name (e.g. hexbug). In the locusts video set, the suffix after the dash (-noqr, -qr, -mix) indicates whether individuals are tagged with Aruco markers. - N stands for the number of filmed individuals Video Set 1: guppies 1. guppy_20200727_8.mp4 This is a video of 6:40 minutes of 8 guppies (Poecilia reticulata). The video was originally recorded at 30 frames per second but the playback in this file is set to 25 frames per second. Video Set 2: hexbugs 2. hexbug_20250129_5.mp4 This is a video of 2:47 minutes of 5 hexbugs. The video was originally recorded at 50 frames per second but the playback in this file is set to 30 frames per second.
