Figure 2: The ratio of unique-m versus unique 25-mers in various genomes. The numbers of unique 25-mers were computed first. Then unique-m 25-mers were identified for the seven species. We increased the m value up to 3 while we only computed the unique-1 25-mers for the human genome. Finally the ratio of unique-m versus unique in each genome was plotted against the m value.
