Understanding Outputs

This page provides an overview of Space Ranger outputs for various supported workflows with links to detailed documentation for each of them.

Overview of output structure

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

• For spaceranger mkfastq, the --id argument is used or if unspecified the flow cell ID is used (e.g., HAWT7ADXX)
• For spaceranger count, spaceranger aggr, spaceranger targeted-compare the --id argument is used

Output files appear in the outs/ subdirectory within this pipeline output directory. For example, a typical spaceranger count analysis may display the following after completion:

$ cd /home/jdoe/runs
$ spaceranger count --id=sample345 \
                 --fastqs=/home/jdoe/runs/HAWT7ADXX/outs/fastq_path \
                 --transcriptome=/opt/refdata-gex-GRCh38-2020-A \
                 --image=/home/jdoe/runs/image.tif \
                 --slide=V19J01-123 \
                 --area=B1

Pipestance completed successfully!

In this case:

• /home/jdoe/runs/ is where the pipeline was run
• /home/jdoe/runs/sample345/ is the top-level output directory containing pipeline metadata
• /home/jdoe/runs/sample345/outs/ contains the final pipeline output files

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

Space Ranger output files summary

The Space Ranger 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 Visium-specific data, including spot and molecular barcodes, can be accessed via any third-party tools or scripts that can parse the additional elements utilized by Space Ranger.

Primary analysis: spaceranger count

The outputs generated from the primary analysis pipeline spaceranger count for Gene Expression (GEX) contained in outs/ directory are summarized below:

Outputs for supported libraries of spaceranger count

The spaceranger count pipeline for Gene Expression, and Targeted Gene Expression analysis will output each of the types of files listed above. There are additional output files for CytAssist enabled Gene Expression, and Targeted Gene Expression libraries. For specific analysis output descriptions, select the library type below to go to the associated output documentation pages:

• CytAssist enabled Spatial Gene Expression: Spatial folder + Web Summary file
• Targeted Gene Expression: Targeted GEX Outputs
  • Additional analysis: Targeted-Compare outputs

Additional analysis: spaceranger aggr

The spaceranger aggr pipeline will output metrics file, web summary, filtered feature-barcode matrices, and a .cloupe file all within the outs/ directory. Refer to the aggr outputs section for more details.
