CLUSTALO

Multiple alignment of nucleic acid and protein sequences.

Example

This wrapper can be used in the following way:

rule clustalo:
    input:
        "{sample}.fa"
    output:
        "{sample}.msa.fa"
    params:
        extra=""
    log:
        "logs/clustalo/test/{sample}.log"
    threads: 8
    wrapper:
        "v2.6.0/bio/clustalo"

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.
