stepPairs

Find cell indices and timepoints where these cells both have a step.

Methods for analyzing (cell) motion in two or three dimensions.
Available measures include displacement, confinement ratio, autocorrelation,
straightness, turning angle, and fractal dimension. Measures can be applied to entire tracks,
steps, or subtracks with varying length. While the methodology has been developed for
cell trajectory analysis, it is applicable to anything that moves including animals,
people, or vehicles.
Some of the methodology implemented in this packages was described by:
