Figure 2. Distribution of gene classifications.

These pie charts detail the portion of genes falling into each of the four categories based on their position relative to ChIP-Seq peaks: Upstream, Downstream, Within and No peak. The label above each pie chart indicates the program with which the pie chart is associated. In all cases, the blue portion represents the genes with an upstream peak, the red represents genes with a downstream peak, the green represents genes with a peak within the gene, and the purple represents genes with no peak identified.
