GATK SCATTERINTERVALSBYNS

https://img.shields.io/github/issues-pr/snakemake/snakemake-wrappers/bio/gatk/scatterintervalsbyns?label=version%20update%20pull%20requests

Run gatk ScatterIntervalsByNs.

URL: https://gatk.broadinstitute.org/hc/en-us/articles/9570421542811-ScatterIntervalsByNs-Picard-

Example

This wrapper can be used in the following way:

rule gatk_scatter_interval_by_ns:
    input:
        ref="genome.fasta",
        fai="genome.fasta.fai",
        dict="genome.dict",
    output:
        intervals="genome.intervals",
    log:
        "logs/genome.log",
    params:
        extra="--MAX_TO_MERGE 10 --OUTPUT_TYPE ACGT",
        java_opts="",  # optional
    resources:
        mem_mb=1024,
    wrapper:
        "v5.0.0/bio/gatk/scatterintervalsbyns"

Note that input, output and log file paths can be chosen freely.

When running with

snakemake --use-conda

the software dependencies will be automatically deployed into an isolated environment before execution.

Notes

  • The java_opts param allows for additional arguments to be passed to the java compiler, e.g. “-XX:ParallelGCThreads=10” (not for -XmX or -Djava.io.tmpdir, since they are handled automatically).

  • The extra param allows for additional program arguments.

Software dependencies

  • gatk4=4.6.1.0

  • snakemake-wrapper-utils=0.6.2

Input/Output

Input:

  • reference genome

Output:

  • interval list
