=: Complete match of intron chain. c: Contained by a reference transcript. j: Potentially novel isoform. e: Single exon transfrag overlapping a reference exon and at least 10 bp of reference intron. i: Intronic transcript. o: Generic exonic overlap with a reference transcript. p: Possible polymerase run-on fragment. u: Unknown, intergenic transcript. x: Exonic overlap with reference on the opposite strand. s: Transcript overlap with reference intron on the opposite strand
