MULTIQC

Generate qc report using multiqc.

URL: https://multiqc.info/

Example

This wrapper can be used in the following way:

rule multiqc_dir:
    input:
        expand("samtools_stats/{sample}.txt", sample=["a", "b"])
    output:
        "qc/multiqc.html"
    params:
        extra=""  # Optional: extra parameters for multiqc.
    log:
        "logs/multiqc.log"
    wrapper:
        "v1.15.2/bio/multiqc"

rule multiqc_file:
    input:
        expand("samtools_stats/{sample}.txt", sample=["a"])
    output:
        "qc/multiqc_a.html"
    params:
        extra="",  # Optional: extra parameters for multiqc.
        use_input_files_only=True, # Optional, use only a.txt and don't search folder samtools_stats for files
    log:
        "logs/multiqc.log"
    wrapper:
        "v1.15.2/bio/multiqc"

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.

Software dependencies

• multiqc=1.12

Input/Output

Input:

• input directory containing qc files, default behaviour is to extract folder path from the provided files or parent folder if a folder is provided.

Output:

• qc report (html)

Params

• use_input_files_only: if this variable is set to True input will be used as it is, i.e no folder will be extract from provided file names
