Quick check of run quality

Checking coverage on the target regions can be a quick way to determine if the map/align step ran as expected. Following the enrichment and sequencing guidelines, the Mean Target Coverage (MTC) Depth for tumor samples is expected to be ≥130x, for normal samples ≥50x. This metric is called "Average alignment coverage over target region" and can be found in the <sample>.target_bed_coverage_metrics_<tumor/normal>.csv file. Note that results for "Target bed" should be evaluated, as DRAGEN Report defaults to genome, while this is a target-based, WES, assay. Another metric to check is "Aligned reads in target region", which gives a percentage of the reads in the target region relative to the entire genome and can be thought as Percent Read Enrichment. Other quality metrics to check can include the percentage of Mapped Reads (aim of ≥ 90%) and the Insert length (aim of ≥ 125bp) in the <sample>.mapping_metrics.csv file.
