Space Ranger2.0, printed on 02/26/2024
This page provides an overview of Space Ranger outputs for various supported workflows with links to detailed documentation for each of them.
All pipelines produce all of their output in a single pipeline output directory, whose name depends on the pipeline:
--id argument is used or if unspecified the flow cell ID is used (e.g.,
--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 Running preflight checks (please wait)...

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.
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.
The outputs generated from the primary analysis pipeline spaceranger count for Gene Expression (GEX) contained in
outs/ directory are summarized below:
|Data summary with images, metrics, and plots that can be used for quality assessment as well as errors and warnings related to data quality
|Metrics for quality assessment
|Loupe Browser file for data visualization and analysis
|Secondary analysis results (clustering, DGE, Moran's I)
|Folder containing Visium-specific outs: QC images to check image processing pipeline, downsampled input images, and files that describe spot barcode locations in the images
|Molecule level information used in additional pipelines
(spaceranger aggr, spaceranger targeted-compare)
|Barcoded BAM (optional)
|Read alignment files
|Filtered GEX Matrix
|Feature barcode matrices that contains only tissue-associated barcodes and are used in secondary analysis in R/Python
|Unfiltered GEX Matrix
|Feature barcode matrices that contains both tissue-associated as well as background barcodes and are used in secondary analysis in R/Python
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:
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.
