  1. All tracks were taken from the UCSC Genome Browser [10] except for GENCODE [2], which was downloaded from the GENCODE website http://www.gencodegenes.org/releases/. Junction coordinates from hg38 annotations were lifted over to hg19 before the union was performed. Of all gene annotations listed here, the Swiss Institute of Bioinformatics (SIB) genes has the most, with more than 400,000 junctions for each of hg19 and hg38
