Left figure shows the histogram of the number of occurrences of the three phases in the overlap of a given type as a function of the overlap length. Right figure shows the probability of observing one of the three phases in the overlap of a given type conditioned on the restriction that the length of the overlap is longer than x. In each figure the three panels refer to codirectional (top), convergent (middle), and divergent (bottom) overlaps. The color code is (i) for codirectional overlaps (123:231) (red), (123:312) (green) and (123:123) (blue). (ii) for convergent and divergent overlaps (123:132) (green), (123:321) (blue) and (123:213) (red).
