Figure 4

Boxplot of R2 for unique genes in the Wold brain data. We divided the genes with at least one read into six groups according to their RPKMs: <1, 1 to 5, 5 to 15, 15 to 30, 30 to 100, and >100; each group contains 4,205, 3,320, 2,807, 1,330, 1,094, and 383 genes, respectively. Note that in these data, 1 RPKM stands for 0.034 reads per nucleotide on average, a gene with RPKM >30 is considered to be relatively abundant, and a gene with RPKM <1 is not robust even for transcript detection [7].
