Figure 3From: Quantification of histone modification ChIP-seq enrichment for data mining and machine learning applicationsAverage histone modification enrichments stratified by gene length. Plots of average enrichment profiles from the transcription start site to 6000 bp into the gene body for H3K36me3 (A), H3K79me2 (B), and H3K79me3 (C), stratified by quintiles of gene length. The variability in slope for each of these marks suggests that the enrichment pattern for each of these marks scale with gene length. For example, for the smallest 20%-ile of genes, H3K36me3 enrichment rapidly rises from the TSS to 6000 bp into the gene body; however, for each successive 20%-ile of increasing gene length, the rate of increase in enrichment is diminished for the same region.Back to article page
