Accelerated GATK4 CollectWGSMetrics.

This tool applies an accelerated version of the GATK CollectWGSMetrics for assessing coverage and quality of an aligned whole-genome BAM file. This includes metrics such as the fraction of reads that pass the base and mapping quality filters, and the coverage levels (read-depth) across the genome. These act as an overall quality check for the user, allowing assessment of how well a sequencing run has performed.

Quick Start

            # This command assumes all the inputs are in INPUT_DIR and all the outputs go to OUTPUT_DIR.
$ docker run --rm --gpus all --volume INPUT_DIR:/workdir --volume OUTPUT_DIR:/outputdir \
    --workdir /workdir \
    nvcr.io/nvidia/clara/clara-parabricks:4.1.0-1 \
    pbrun bammetrics \
    --ref /workdir/${REFERENCE_FILE} \
    --bam /workdir/${INPUT_BAM} \
    --out-metrics-file /outputdir/${METRICS_FILE}

Compatible GATK4 Command

The command below is the GATK4 counterpart of the Parabricks command above. The output from this command will be identical to the output from the above command.
