Figure 4From: Evaluation of reference-based two-color methods for measurement of gene expression ratios using spotted cDNA microarraysVariance of reconstructed expression ratios along the range of expression intensities. Each panel shows a different pair-wise tissue comparison. The graphs show the variance of log2-ratios (Y axis) from all technical replicates that was calculated by using a sliding window of 1.5, moving 0.4 at each step along the range of average expression log2-intensities A (X axis).Back to article page
