Figure 1. CpG Island Positional Bias.

Figure 1

CpG island expectancy is plotted for each chromosome as a function of the distance from the TSS. This type of data was used to normalize many of the features in this study for distance from the TSS. In this figure, the expectancy of being in a CpG island at position −1 for any promoter region is ~0.5.
