Figure 7From: Characterization of the expression ratio noise structure in high-density oligonucleotide arraysIntensity dependence of the noise envelope: STD of the log2-ratios from 40 pairs of replicate HG-U95A experiments. The errors represent the variation in local STD from the 40 replicates. The intensity I = IX * IY)1/2 measures the coordinate along the diagonal of the scatterplots.Back to article page
