Fig. 3

Displayed is the number of exon-exon junctions J found in at least P projects of the 929 human RNA-seq projects on the SRA considered in this paper. It also shows how much evidence for these junctions is found in gene annotation: “fully annotated” (orange) means the junction is in an annotated transcript, “exon skip” (green) means a called junction’s donor and acceptor sites are annotated in distinct junctions, “alternative donor/acceptor” (red) means only one of a called junction’s donor and acceptor sites is in a junction from annotation, and “novel” (blue) means neither donor nor acceptor site is annotated
