Fig. 4From: Removing reference bias and improving indel calling in ancient DNA data analysis by mapping to a sequence variation graphComparison between vg and bwa aln for indel detection. a Alternate allele observations at indels. b Comparison between vg graph and bwa aln in the detection of the CCR5 delta 32 deletion associated with HIV-1 resistance. Reads containing the deletion were mapped with vg in four ancient samples, but not with bwaBack to article page
