Fig. 2From: A verified genomic reference sample for assessing performance of cancer panels detecting small variants of low allele frequencyDefining the consensus target region (CTR). The regions shown are not to scale. Most of these regions and their sizes are provided in Additional file 1: Table S2. The low complexity regions are excluded from the CTR. Importantly, the size of the CTR is ~ 22.7 Mb for hg19Back to article page
