Enrichment in new 5′/3′-ASS events according to the size of the events. (A) Number of new 5′/3′-ASS events found at discrete size intervals within the Control and AS libraries. (B) Enrichment level in new 5′/3′-ASS events at the same discrete size intervals (the enrichment level in new 5′/3′-ASS events at a given size interval is the ratio between the number of new 5′/3′-ASS events found within the AS library at this size interval and the number of new 5′/3′-ASS events found within the Control library at the same interval).
