Original S98 Array correlation map compared to the corrected one.
The two dimensional map of the average correlation between two different probes on the Affymetrix Yeast Genome S98 Array as a function of the separation (dx,dy) for the original data (a) and the corrected data (b). The separation between two neighboring probes (24 μm) is used as a unit of distance.
