Example

This wrapper can be used in the following way:

rule diamond_blastp:
    input:
        fname_fasta="{sample}.fasta",  # Query fasta file
        fname_db="db.dmnd",  # Diamond db
    output:
        fname="{sample}.tsv.gz",  # Output file
    log:
        "logs/diamond_blastp/{sample}.log",
    params:
        extra="--header --compress 1",  # Additional arguments
    threads: 8
    wrapper:
        "v1.1.0/bio/diamond/blastp"

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.
