[i] Only exons that are part of a transcript-pair are compared with each other. An annotated exon is considered found if there is at least one predicted exon with exact matching boundaries in a given transcript-pair. The second and fourth columns give the percentage of exact exon matches from the total number of exon-pairs formed within the transcript-pairs for all-exons and for coding exons, respectively. The sensitivity and specificity values are also given. The values are higher for coding exons, which indicates that UTR annotation remains a difficult problem.
