Differential enrichment (DE) analysis of ATAC peaks at transcriptional start sites (TSSs). a Scatterplot of peaks located at TSSs. Red dots indicate differentially enriched ATAC peaks. b Cluster analysis (Pearson correlation). c Principal component analysis of ATAC peaks located at TSSs (control in blue, exposed in red). d Top 10 gene ontology enrichment analysis (GO term biological process) of DE peaks at TSSs
