Purge haplotigs and overlaps in an assembly based on read depth

URL: https://github.com/dfguan/purge_dups

Example

This wrapper can be used in the following way:

rule purge_dups_ngscstat:
    input:
        bam="reads.bam",
    output:
        cov="out/ngscstat.cov",
        stat="out/ngscstat.stat",
    log:
        "logs/ngscstat.log",
    params:
        extra="",
    threads: 1
    wrapper:
        "v3.8.0-49-g6f33607/bio/purge_dups/ngscstat"

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 extra param allows for additional program arguments.
