ATAC-seq (Assay for Transposase-Accessible Chromatin with high-throughput sequencing) is a method for determining chromatin accessibility across the genome. It utilizes a hyperactive Tn5 transposase to insert sequencing adapters into open chromatin regions (Fig. 1). High-throughput sequencing … See more The developers of the ATAC-seq method have published a detailed protocol for the laboratory procedure (Buenrostro et al., 2015). Here are a few additional things to consider when … See more This document assumes that you have an account on the Cannon computer cluster of Harvard University. An account can be requested here. Programs, like those listed below (e.g. … See more The raw sequence files generated by the sequencing core are in FASTQ format. They are gzip-compressed, with .gzfile extensions. It is … See more WebDec 11, 2024 · Because ATAC represents open chromatin (DNA without any binded proteins) and chip histone modification (DNA is actually wound on histone proteins), hence we have something like this figure C, first we see high ATAC peak - open chromatin, then H3k27ac peak - lysine acetylated = gene activated. In other words ATAC-seq won't … WebFeb 25, 2024 · Just count the number of reads overlapping an ATAC-seq peak and divide it by the length of the peak gives you the read density. Each dot is a fold change, but to calculate fold change, average density from all the samples are taken, that is what the "average" is referring to. Share. Improve this answer. Follow. proshopping
