The read mapping summary for 16 tissue samples in the
mapping modes (note: read length
75 bp). In the “transcriptome only” mode, more reads are mapped in Ensembl than in RefGene and UCSC (left panel), and more reads become multiple-mapped in Ensembl than in RefGene and UCSC (right panel). Note: the gene model “none” means the RNA-Seq reads are mapped to the reference genome directly without the use of a gene model.
