WebSep 29, 2024 · The default method is for ChIP-seq peak-calling but there is an ATAC-seq specific mode which can be enabled by the -j parameter. To account for the manner in which the Tn5 enzyme inserts itself into the genome, Genrich centers a 100 bp interval on the end of each correlating fragment. It uses the log-normal distribution to calculate p-values ... WebJan 1, 2024 · In this tutorial, we demonstrate how to call peaks on a single-cell ATAC-seq dataset using MACS2. To use the peak calling functionality in Signac you will first need to install MACS2. This can be done using pip or conda, or by building the package from source. In this demonstration we use scATAC-seq data for human PBMCs.
