WebIn this tutorial, we go over how to use scvi-tools functionality in R for analyzing ATAC-seq data. We will closely follow the PBMC tutorial from Signac, using scvi-tools when appropriate. In particular, we will. Use PeakVI for dimensionality reduction and differential accessiblity for the ATAC-seq data. Use scVI to integrate the unpaired ATAC ... 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.
