Atac-seq peak calling
WebApr 14, 2024 · We carried out a sequential classification scheme to sort the ATAC-seq peaks into promoter (P), enhancer (E), and other (O) based ATAC-seq union peak set. The ±3 kb windows of the TSSs of all expressing genes (mean FPKM of the twelve samples > 0 as determined from RNA-seq data) were used to intersect with ATAC-seq union peaks … WebApr 1, 2024 · Because the ATAC-seq fragments are mixture of nucleosome-free fragments and fragments with nucleosome between mates, you need to adapt the parameters of peak calling algorithms. We recommand MACS2 with adapted parameters. Speaker Notes During the process, the Tn5 introduces a 9bp duplications.

WebFeb 3, 2024 · Here, we discuss the major steps in ATAC-seq data analysis, including pre-analysis (quality check and alignment), core analysis (peak calling), and advanced analysis (peak differential analysis and annotation, motif enrichment, footprinting, and nucleosome position analysis). WebAnother way to assess concordance of peak calls between replicates is to implement a statistical procedure. A popular method is the IDR framework developed by Qunhua Li and Peter Bickel’s group. It compares a pair of ranked lists of regions/peaks and assigns values that reflect its reproducibility.
