Welcome to NVIDIA Parabricks v4.7.0

starfusion

Identifies candidate fusion transcripts.

This tool performs fusion calling for RNA-Seq samples, utilizing the STAR-Fusion algorithm. This requires input of a genome resource library, in accordance with the original STAR-Fusion tool, and outputs candidate fusion transcripts.

See the starfusion Reference section for a detailed listing of all available options.

# This command assumes all the inputs are in the current working directory and all the outputs go to the same place. docker run --rm --gpus all --volume $(pwd):/workdir --volume $(pwd):/outputdir \ --workdir /workdir \ nvcr.io/nvidia/clara/clara-parabricks:4.7.0-1 \ pbrun starfusion \ --chimeric-junction /workdir/${CHIMERIC_JUNCTION_INPUT} \ --genome-lib-dir /workdir/${PATH_TO_GENOME_LIBRARY}/ \ --output-dir /outputdir/${PATH_TO_OUTPUT_DIRECTORY}/

The command below is the CPU counterpart of the Parabricks command above. The output from this command will be identical to the output from the above command.

Description

I/O --chimeric-junction CHIMERIC_JUNCTION Yes Path to the Chimeric.out.junction file produced by STAR.
I/O --genome-lib-dir GENOME_LIB_DIR Yes Path to a genome resource library directory. For more information, visit https://github.com/STAR-Fusion/STAR-Fusion/wiki/installing-star-fusion#data-resources-required.
I/O --output-dir OUTPUT_DIR Yes Path to the directory that will contain all of the generated files.
Tool --out-prefix OUT_PREFIX No Prefix filename for output data.
Performance --num-threads NUM_THREADS No Number of threads for worker. (default: 4)
Runtime --verbose No Enable verbose output.
Runtime --x3 No Show full command line arguments.
Runtime --logfile LOGFILE No Path to the log file. If not specified, messages will only be written to the standard error output.
Runtime --tmp-dir TMP_DIR No Full path to the directory where temporary files will be stored. (default: .)
Runtime --with-petagene-dir WITH_PETAGENE_DIR No Full path to the PetaGene installation directory. By default, this should have been installed at /opt/petagene. Use of this option also requires that the PetaLink library has been preloaded by setting the LD_PRELOAD environment variable. Optionally set the PETASUITE_REFPATH and PGCLOUD_CREDPATH environment variables that are used for data and credentials. Optionally set the PetaLinkMode environment variable that is used to further configure PetaLink, notably setting it to "+write" to enable outputting compressed BAM and .fastq files.
Runtime --keep-tmp No Do not delete the directory storing temporary files after completion.
Runtime --no-seccomp-override No Do not override seccomp options for docker.
Runtime --version No View compatible software versions.
Runtime --preserve-file-symlinks No Override default behavior to keep file symlinks intact and not resolve the symlink.
