Examples of network motif distributions. Three examples of classes of synthetic networks and corresponding motifs that exhibit non-normal asymptotic frequency distributions. Top row: An illustrative network from each class. Middle row: A motif candidate. Bottom row: The form of the frequency distribution of the given motif candidate, calculated for networks drawn from the corresponding class. For full details see SI S2.2 for discussion of the Poisson distribution example, S2.3 for discussion of the binomial distribution example, and S2.4 for discussion of the multimodal example
