1Because there are overlaps among Refgene intronic and intergenic regions due to alternative spliced isoforms, the number of novel exons is more than the total of intronic exons and intergenic exons. 2These exons are in known introns. 3These exons reside in intergenic regions. 4Inconsistent TUs means those have abnormal exon-patterns, such as non-coding-coding-non-coding-coding. 5Because sometimes two adjacent TUs are combined into one in intergenic regions, we correct them manually to yield modified non-coding TUs. 6The number of identified regions and their reads are outside and inside the parentheses, respectively.
