<p>pTrk (numpoints x numdimensions x numframes x numtargets) – Contains the position information for manually labeled points (OR tracked points?), unlabeled frames have NaN values. For example: if there are two labeled body points for a single target from a single viewpoint video with 10800 frames, then pTrk is 2x2x10800, where pTrk(1,1,15) is the x coordinate of the first point for frame 15, pTrk(1,2,10400) is the y coordinate of the fir
