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. WebFeb 3, 2024 · Currently, most studies assume that ATAC-seq reads in peak regions follow a NB distribution, as is the case for RNA-seq data. However, no shape-based differential analysis tools exist for ATAC-seq data. The peaks contain not only read count information, but also the distribution shape profile. It is especially important for broad peaks, as ...
