Regions were chosen to target peaks with a range of fold-enrichments. The results are summarized in Fig. 2, with the ChIP-Seq fold enrichment of each called peak indicated below the graphs. While fold enrichment …
WebChIP Analysis. ChIP-qPCR data needs to be normalized for sources of variability, including amount of chromatin, efficiency of immunoprecipitation, and DNA recovery. Here we discuss two common methods used to normalize ChIP-qPCR data—the Percent Input Method and the Fold Enrichment Method. We prefer analyzing ChIP-qPCR data relative to input ...
WebAug 30, 2012 · The 'fold_enrichment' column shows the ratio of the ChIP-seq read count to the local value of lambda within each peak. The 'FDR(%)' column contains the empirical FDR percentage for each peak.
