Fig. 1From: CarrierSeq: a sequence analysis workflow for low-input nanopore sequencingReceiver operating characteristic curve. Q9 provides a good threshold which discards the majority of low-quality and noise reads (0.76 True Positive Rate and 0.03 False Positive Rate) for carrier runs that are 99% Lambda DNA by mass. A perfect quality score threshold would plot in the top left of the ROC curveBack to article page
