Examples of visualization and analysis by DROMPA. We reanalyzed (a) Saccharomyces cerevisiae Scc1 ChIP-seq data from ) and (b) D. melanogaster Suppressor of Hairy-wing, Su(Hw), ChIP-seq data from ) using DROMPA. The orange, green and blue histograms represent ChIP/control ratio, ChIP read distributions and input-read distributions, respectively. The y-axis values of the read distribution histograms are the normalized ChIP read intensities (Rx) for each bin (see Experimental Procedures). (a) Part of S. cerevisiae chromosome II (nucleotide numbers 230–300 kbp) with Saccharomyces Genome Database annotation. The red boxes and blue box indicate true and pseudobinding sites, respectively. The black arrow indicates a region with few mapped reads. (b) Part of Drosophila melanogaster chromosome 2L (build dm3, nucleotide numbers 13.6–13.7 m) with RefSeq gene annotation. In the gene annotation, the thick lines indicate DNA exons and the thin lines indicate DNA introns. For the top two panels, reads uniquely mapped to the genome were used. For the bottom two panels, both multiply and uniquely mapped reads were used. Regions in which reads were significantly enriched are in red.
