Description

Percent Reads With Usable UMIs

The percentage of reads with usable UMIs.

Percent Duplex Families

The percentage of the total number of families that are duplex families.

Percent Families Collapsed

The percentage of the total number of families that are collapsed.

CV UMI Coverage

The coefficient of variation of the number of families associated with each UMI.

Percent Families Depth >= 5

The number of families with greater than or equal to 5 supporting reads.

Mean Family Depth

Average number of fragments (paired reads) in a family before UMI collapsing.

Mean Family Depth Meets Threshold

Mean Family Depth is greater than or equal to 10 (Derived from ctDNA with TruSight Tumor 170 Workflow).

Median Target Coverage

Median Target Coverage across all base positions.

Median Target Coverage Meets Threshold

Median Target Coverage is greater than or equal to 954 (Derived from ctDNA with TruSight Tumor 170 Workflow).

CV Median Target Coverage

Coefficient of Variation of the Median Target Coverage across all base positions.

Bases with >= 1000x Coverage (%)

Percentage of positions with coverage greater than 1000.
