Figure 7From: How to decide? Different methods of calculating gene expression from short oligonucleotide array data will give different resultsRelation between PM and MM signals. Slope and Pearson correlation coefficient calculated between the PM and MM signals from 200 random chosen probe sets. Only probe sets are used which represents one gene. Both slope and correlation are sorted from low to high. See figure 6 for further explanation and individual examples.Back to article page
