Multiomics Pipeline

The DRAGEN Single-Cell Multiomics (scRNA + scATAC) Pipeline can process data sets from single-cell RNA-Seq and ATAC-seq reads to a cell-by-feature count matrix.

The pipeline is compatible with library designs that have:

Single-cell RNA: One read in a fragment match to a transcript and the other containing a cell-barcode and UMI
Single-cell ATAC: Two reads matching to the genome and the third one containing cell-barcode

The pipeline includes the following functions:

Alignment
RNA-Seq (splice-aware) alignment and matching to annotated genes for the transcript reads
ATAC-seq alignment
Cell-barcode (both RNA- and ATAC-seq) and UMI (RNA-Seq only) error correction for the barcode read
Read counting
UMI counting per cell and gene to measure gene expression
Fragment counting per cell and peak to measure chromatin accessibility
Sparse matrix output and QC metrics
