  1. aThe frequency of contacts is calculated as the average number of contacts between two 1 Mb-size windows
  2. bThe bipartite index represents the ratio between the frequency of intra-superdomain contacts to inter-superdomain contacts
  3. cThe p value is calculated by one-sided Z-test to measure the significance of the observed superdomain boundary compared with randomly shifted boundaries
