DNA Library QC Metrics for Copy Number Variant Calling

Metric

Description

Recommended Threshold

PCT_CHIMERIC_READS (%)

Percentage of unique reads that are part of a chimeric alignment (for example, half of the read maps to one location and the other half maps to a nonsequential location) out of the total number of mapped unique reads.

≤ 3.5

COVERAGE_MAD

Median of absolute deviations from the median of the normalized count of each CNV target region.

≤ 0.2

MEDIAN_BIN_COUNT_CNV_TARGET

Median of the raw read counts (normalized by region size) of each CNV target region.

≥ 1
