ATAC-seq, known as Assay for Transposase Accessible Chromatin with high-throughput sequencing, is a method for mapping chromatin accessibility genome-wide. This method probes DNA accessibility with hyperactive Tn5 transposase, which inserts sequencing adapters into accessible regions of chromatin. Sequencing reads can then be used to infer regions of increased accessibility, as well as to map regions of transcription-factor binding and nucleosome position. The SCAN_ATAC module help users to analyze and explore the ATAC-seq datasets of different nervous system tissues. Users can choose the tested species and tissues from the above select box or the pictures, and the details about the ATAC-seq datasets will show up automatically. Then, users can download the bed file and view details for each data sets.
