Gene expression correlation between Affymetrix microarray and Illumina RNA-Seq platforms. A: Expression correlation of the 16,097 genes measured both on Affymetrix microarray and Illumina RNA-Seq platforms after selecting the best Affymetrix probeset using jetset. B: and C: Box plots showing median level of gene expression for both Affymetrix and RNA-Seq for the genes with low (<0.7) and high (≥0.7) correlation. Genes highly correlated between the two platforms showed higher levels of expression than those with low correlation.
