Calculation of spatial correlation function. (a) Gray-scale TEM image of an example nucleus from a human sample, (b) color-coded map of 2-D spatial correlation function obtained from it. Black dashed circle outlines data points corresponding to the same separation r, and (c) 1-D spatial correlation function calculated by averaging data for each separation r (red circles) and the analytical correlation function fitted to the experimental (black solid line).
