Cell Ranger ARC strives to maintain compatibility with common analysis tools by using standard output file formats whenever possible. The Chromium-specific data, including cellular and molecular barcodes, can be accessed by third-party tools or scripts that can parse the additional elements utilized by Cell Ranger ARC.

All pipeline outputs are produced in a single pipeline output directory, which is specified by the --id argument for both cellranger-arc count and cellranger-arc mkfastq (defaults to the flow cell serial number, e.g., HAWT7ADXX when the --id argument is not specified).

Output files will appear in the outs/ subdirectory within this pipeline output directory. For example:

In this case,

• /home/jdoe/runs/ is where the pipeline was run,
• / is the top-level output directory containing pipeline metadata
• /outs/ contains the final pipeline output files.

The contents of this outs/ directory contain the data that is described in the remainder of this section:

• Multiomic outputs:

  • Web summary HTML, run summary metrics, and per barcode summary metrics
  • Secondary analysis including feature linkage
  • Feature-barcode matrices in MEX and HDF5 formats

• ATAC outputs:

  • ATAC position-sorted alignments BAM
  • ATAC peaks and ATAC peak annotations
  • ATAC per fragment information file and ATAC smoothed transposition site track](/support/software/cell-ranger-arc/latest/analysis/transposition-counts)

• Gene Expression outputs:

  • GEX position-sorted alignments BAM
  • GEX molecule info HDF5

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