Fly and mouse tracking models and kinematics related to Anipose toolkit paper

This is a series of datasets related to the Anipose paper. We provide
these to allow others to reproduce our tracking results and build upon
them. Anipose is an open-source toolkit for robust markerless 3D pose
estimation. Anipose is built on the 2D tracking method DeepLabCut, so
users can expand their existing experimental setups to obtain accurate 3D
tracking. It consists of four components: (1) a 3D calibration module, (2)
filters to resolve 2D tracking errors, (3) a triangulation module that
integrates temporal and spatial regularization, and (4) a pipeline to
structure processing of large numbers of videos. Applying 3D tracking to
estimate joint angles of walking Drosophila, we found that flies move
their middle legs primarily by rotating their coxa and femur, whereas the
front and rear legs are driven primarily by femur-tibia flexion. We then
show how Anipose can be used to quantify differences between successful
and unsuccessful trajectories in a mouse reaching task. We share these fly
and mouse datasets and tracking models in this dataset to allow others to
reproduce our findings and reuse the training data and models in their
research.
