Figure 4.
Scatter-plots for the counts of all n-mers (4–7 nt) in the CS samples (NCS) vs. the counts in the corresponding random samples (NRS). Overlaid on plots A and C are the n-mers that were significantly enriched (according to the confidence intervals described in the Supplemental Materials and Methods) in the donor intronic (DI) and acceptor intronic (AI) regions. Overlaid on plots B and D are all n-mers containing the substrings indicated. These substrings are examples of substrings that are enriched in the corresponding regions.
