RUbitrail

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)
