trackpy.diagonal_size¶

trackpy.diagonal_size(single_trajectory, pos_columns=None, t_column='frame')¶

Measure the diagonal size of a trajectory.

Parameters:	single_trajectory : DataFrame containing a single trajectory pos_columns = list names of column with position [‘x’, ‘y’] t_column = ‘frame’
Returns:	float : length of diangonal of rectangular box containing the trajectory

Examples

>>> diagonal_size(single_trajectory)

>>> many_trajectories.groupby('particle').agg(tp.diagonal_size)

>>> many_trajectories.groupby('particle').filter(lambda x: tp.diagonal_size(x) > 5)
