  1. Abbreviations: 3 TERM, read which extend the annotated 3'term of the target gene. Poli-A: read which extends at 3' the last exon. INTERNAL: read which extends at 3' any exon except the last. 5 TERM: read which extend the annotated 5' term of the target gene. TSS: read which extends at 5' the first exon. INTERNAL: read which extends at 5' any exon except the first. EXON: read mapping inside an exon with one or both ends coincident with exon boundaries. INTRAEXON: read mapping completely inside an exon of the target gene. INTRON: read mapping completely inside an intron.
