Figure 1

Homo sapiens orderings for different values of α . A-D) Adjacency matrix (black dots) for values of α as indicated in the legends. The axes have been normalized; the number of gene positions in each axis is 9684. The landscapes indicate the window modularity calculated with r = 80 (yellow), r = 200 (gray), and r = 1000 (magenta). Window modularity for r = 80 is not shown for α = 10.0 because it blurs the image. E) Probability of association between two genes separated by d positions on the ordered list, for different values of α.
