WebDec 7, 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.
