Figure 2From: Large scale analysis of positional effects of single-base mismatches on microarray gene expression data Distribution of log 2 (PM/MM i ) across 25 single-base-pair mismatch positions. The red dashed line represents the mean value of log2(PM/MMi) when there was no mismatch, i.e., the common PM probes from the HGU133plus2.0 GeneChip and the Rhesus macaque GeneChip.Back to article page
