Figure 1.

Normalization of hybridization intensity profile of 25mer probes in a probe set. The y axis is background-corrected normalized log intensity and the x-axis shows the positions of the 11 features along the unigene. Black lines trace the Golden Promise arrays, while red trace the Morex arrays. Different line types differentiate tissues. Each panel illustrates normalization for one of the major sources of variation: probe effect; probe and tissue; probe and genotype; probe, genotype and tissue; probe, genotype, tissue and genotype by tissue. 100 such plots are available from [35].
