An R package to analyse the output of Ubitrail, an open-source software for tracking animal locomotion. Together, these aim to provide a complete toolkit for quantifying two-dimensional locomotory behaviours in animals. Documentation and tutorials on using the software are available here.
RUbtrail's pre-processing steps allow for:
- outlier removal based upon log-likelihood of tracked positions
- trajectory smoothing
- linear interpolation of missing / occluded frames
And further analysis can return data on a range of behavioural metrics, including:
- speed and acceleration
- turning angle
- activity (frequency and duration of bursts / pauses)
- exploration (proportion of area visited)
- thigmotaxis (centrophobism)
