VG CONSTRUCT

Construct variation graphs from a reference and variant calls.

Example

This wrapper can be used in the following way:

rule construct:
    input:
        ref="c.fa",
        vcfgz="c.vcf.gz"
    output:
        vg="graph/c.vg"
    params:
        "--node-max 10"
    log:
        "logs/vg/construct/c.log"
    threads:
        4
    wrapper:
        "0.72.0/bio/vg/construct"

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.
