Understanding Output

Output Overview of Different Pipelines and Products:

The Cell 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 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.

cellranger count

The cellranger count pipeline for gene expression, antibody, CRISPR, and targeted analysis will all output the following files:

In addition to the files listed above, the CRISPR pipeline will also output a CRISPR output CSV file.

The antibody pipeline will produce all of the files listed above and an Antibody t-SNE CSV file.

cellranger reanalyze

The cellranger reanalyze pipeline will produce a secondary analysis web summary, a .cloupe file within a secondary analysis output directory called outs.

cellranger aggr

The cellranger aggr pipeline will output a web summary, matrices and a .cloupe file all within a directory called outs.

Overview of Output Structure

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 count may look like:

$ cd /home/jdoe/runs
$ cellranger count --id=sample345 \
                 --transcriptome=/opt/refdata-gex-GRCh38-2020-A \
                 --fastqs=/home/jdoe/runs/HAWT7ADXX/outs/fastq_path \
                 --indices=SI-3A-A1 \
