Comparison of two arrays by different methods Horizontal axis shows the ratios between two arrays, for 4629 targets, according to the comparative analysis algorithm, which is the basis of the ratio method. Vertical axis shows ratios between the same arrays according to the absolute analysis algorithm, which is the basis of the signal method. Points outside the red lines have more than 1.5-fold divergence between methods.
