Figure 3: Venn diagram of the peak regions of the H3K4me3 data called by five methods: MICS, QuEST, MACS, PICS and BayesPeak. For some methods, the number of peak regions is different from the one reported in the paper, this is because some peak regions obtained by one method are split into multiple regions in another. Under such circumstance, the small adjacent regions are merged together to form a longer peak region.
