Such applications include things like ChIPseq from restricted biological material (eg, forensic, ancient, or biopsy samples) or where the study is limited to recognized enrichment websites, therefore the presence of false peaks is indifferent (eg, comparing the enrichment levels quantitatively in samples of DMOG site cancer individuals, employing only selected, verified enrichment websites over oncogenic regions). On the other hand, we would caution against employing iterative fragmentation in research for which specificity is extra critical than sensitivity, one example is, de novo peak discovery, identification in the precise location of binding internet sites, or biomarker study.
