Exon counts per gene transcript. A comparison of the number of exons per transcript and coding exons per transcript in the GENCODE annotation of the 31 test regions and in the predictions. Blue bars show the average number of coding exons per coding transcript for each of the programs in categories 1, 2, 3, and 4; the blue line shows this for the GENCODE annotation. The number of all exons per transcript in the GENCODE annotation is shown with a red line. Those programs that predict non-coding exons are noted with red bars. Programs marked with an asterisk predict multiple transcripts per gene locus.
