Measuring gene expression. a) DEGseq vs. Cufflinks estimates of log2 fold changes between Large White and Iberian expressed genes. Blue and red points correspond not expressed genes in microarrays and Cufflinks, respectively. Light blue and light red points correspond to microarray and Cufflinks infinite values. b) Microrray vs. RNA-Seq individual measurements. The microarray data correspond to signal intensity difference between Large White and Iberian, whereas the RNA-Seq measurement is the log2 fold change as obtained from Cufflinks. c) Microarray breed z-score values vs. RNA-Seq log2 fold change. The Pearson's correlations (r) were significant in each case (Pv < 2.2 × 10-16) and calculated considering only expressed genes and no infinite values.
