Merging microarray data from separate breast cancer studies provides a robust prognostic test-1

Eat map is generated using the matrix2png software [34]. There are 80 rows corresponding to the 80 gene pairs; the displayed intensities are the differences between the expression values of the two genes in each pair. The expression value for each difference is normalized across the samples to zero mean and one standard deviation (SD) for visualization purposes. Differences with expression levels greater than the mean are colored in red and those below the mean are colored in green. The scale indicates the number of SDs above or below the mean.<p><b>Copyright information:</b></p><p>Taken from "Merging microarray data from separate breast cancer studies provides a robust prognostic test"</p><p>http://www.biomedcentral.com/1471-2105/9/125</p><p>BMC Bioinformatics 2008;9():125-125.</p><p>Published online 27 Feb 2008</p><p>PMCID:PMC2409450.</p><p>
