Example

This wrapper can be used in the following way:

rule bamtobed:
    input:
        "{sample}.bam",
    output:
        "{sample}.bed",
    log:
        "logs/bamtobed/{sample}.log",
    params:
        extra="-bedpe",  # optional parameters
    wrapper:
        "v1.9.0/bio/bedtools/bamtobed"

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.
