Chromium Single Cell ATAC

Understanding Output

The Cell Ranger ATAC software strives to maintain compatibility with common analysis tools by using standard output file formats whenever possible. For example, the barcoded BAM files can be viewed in standard genome browsers such as IGV to verify alignment quality and other features. The Chromium-specific data, including these barcodes, can be accessed via any third-party tools or scripts that can parse the additional element tags utilized by Cell Ranger ATAC.

All pipelines produce all of their output in a single pipeline output directory, whose name depends on the pipeline:

Output files will appear in the outs/ subdirectory within this pipeline output directory. For example, a typical cellranger-atac count may look like:

$ cd /home/jdoe/runs
$ cellranger-atac count --id=sample345 \
                 --reference=/opt/refdata-cellranger-atac-GRCh38-1.0.1 \
                 --fastqs=/home/jdoe/runs/HAWT7ADXX/outs/fastq_path \

In this case,

The contents of this outs/ directory contain the data that is described in the remainder of this section: run summary HTML, run analysis, feature-barcode matrices MEX and HDF5, barcoded BAMs, peaks.bed, fragments tsv.gz and metrics.

More information about the contents of the pipeline output directory can be found in the Pipestance Structure page.
