Figure 4From: Is this the right normalization? A diagnostic tool for ChIP-seq normalizationDiagnostic plots for modENCODE data. Diagnostic plots for the three datasets from modENCODE. Datasets refer to H3K27me3 modification in D melanogaster. Panel (a) refers to ChIP id. 1820 and Input id. 1815, panel (b) to ChIP id 1957 and Input id 1961, panel (c) to the pooled version of the modEncode semples. The five densities are: the density of \(\log \frac {\tilde {N}_{\textit {ch}} (i)}{\tilde {N}_{\textit {in}} (i)}\) in all bins (solid black curve), the density of the subset of bins in last quartile in length (two-dashed pink), the density of the subset of bins in third quartile in length (dashed blue), the density of the subset of bins in second quartile in length (dot-dashed green), and the density of the subset of bins in first quartile in length (dotted red). The vertical lines show the estimated logr using CisGenome (brown line), CCAT (deepink line) and NCIS (navy line). The plot was produced with K=200.Back to article page
