ultrasound .mat files: 
 - datasets containing the structure of a worm tangle which was imaged using ultrasound. 
 - Every .mat file contains a 3N x n array which stores the positions of all the worms in a the tangle, where N is the number of worms, and n is the number of points stored along each worm. 


disentangle_data.mat and entangle.data.mat
 - Data showing the head trajectories of untangling worms (disentangle_data.mat) and tangling worms (entangle_data.mat).
 - Contains TrackList, a N x T x V array, and timeList, a T x V array. The first index labels worms, the second index labels time, and the third index labels distinct worm tangles. i.e TrackList(j, t, i) is the position of head of the j'th worm in the i'th worm tangle at time timeList(t) (given as a complex number). 
 - Entries can be blank if the worm isn't visible at a particular time.
