Coverage Summary

We exclude duplicate reads from the coverage statistics. We calculate the target coverage percentage for non-N reference positions in the targeted regions. Overlapping reads (read1/read2 in a pair) count as twice towards base coverage. The read cycles with no-calls (Ns) are not added to the target coverage.

Statistic

Definition

Mean Target Coverage Depth

The total number of targeted bases divided by the targeted region size.

Uniformity of Coverage (Pct > 0.2*mean)

The percentage of targeted base positions in which the read depth is greater than 0.2 times the mean region target coverage depth.

Percent Target Unique Overlapping Bases

The percent of total PF bases where the base call corresponds to a position on a fragment of a paired-end read that is called in Read 1 and Read 2.

Target Coverage at 1X

Percentage targets with coverage greater than 1X.

Target Coverage at 10X

Percentage targets with coverage greater than 10X.

Target Coverage at 20X

Percentage targets with coverage greater than 20X.

Target Coverage at 50X

Percentage targets with coverage greater than 50X.
