Figure 2From: BABAR: an R package to simplify the normalisation of common reference design microarray-based transcriptomic datasetsMA-plots for a pair of microarrays before (A) and after (B) BABAR. For a pair of microarrays (array 1 vs. array 11 - see Figure 1) from [13], the intensity log-ratio M = log2{(R1/G1)/(R11/G11)} was plotted against the mean log intensity A = log2 √{(R1/G1) × (R11/G11)} for each gene.Back to article page
