Figure 2From: Analysing 454 amplicon resequencing experiments using the modular and database oriented Variant Identification PipelineInfluence of quality score (Q) on homopolymer accuracy. Distribution of homopolymer related quality scores (Q score). The normal homopolymer Q score distribution is determined by making a distribution of the Q score of the homopolymer base; the mismatch homopolymer Q score distribution is determined by making a distribution of the Q score of the base preceding a homopolymer related deletion or the Q score of a homopolymer related inserted base. Distributions are shown for homopolymers with length 3, 5, 6 and 7 bp. The grey vertical lines are drawn at a Q score of 15 and 30. Distributions are based on data from the two BRCA runs.Back to article page
