Example

This wrapper can be used in the following way:

rule homer_getDifferentialPeaks:
    input:
        # peak/bed file to be tested
        peaks="{sample}.peaks.bed",
        # tagDirectory of first sample
        first="tagDir/{sample}",
        # tagDirectory of sample to compare
        second="tagDir/second"
    output:
        "{sample}_diffPeaks.txt"
    params:
        extra=""  # optional params, see homer manual
    log:
        "logs/diffPeaks/{sample}.log"
    wrapper:
        "v1.1.0/bio/homer/getDifferentialPeaks"

Note that input, output and log file paths can be chosen freely.
