Fig. 2From: Detection and quantification of mitochondrial DNA deletions from next-generation sequence dataStandard mitochondrial reference genome numbering shown in interior of the circular genome, with the deleted segment, from base position s + 1 to base position e – 1, indicated in green, and the copy harboring the deletion shown at right. The position x i in a single hypothetical read i (black arc) shown in circle exterior. This read may be unaligned by BWA [17], but BLAT [20] will be able to align its two segments as a split readBack to article page
