Representative time series and standard deviation at every 10th frame, a = 6. (a) Cluster1 is singleton so its standard deviation is 0. It is therefore not shown in the plot. The cluster size is denoted by n. The X-axis denotes the frame number and the Y-axis denotes the ratio of the end point length to the skeleton length.
