From: Quantifying and reducing spurious alignments for the analysis of ultra-short ancient DNA sequences

Fig. 2

Effect of sequence length, indel, and deamination filters on the proportion of spurious alignments. The proportion of spurious alignments in each size bin is shown for all Mezmaiskaya 1 (“Mez”) alignments in black, alignments without indels in orange, alignments with terminal C to T substitutions (“deam”) in blue, and with both filters applied in green. An analysis of modern human sequences (“Control”) without microbial contamination is shown in gray. Ninety-five percent binomial confidence intervals are as wide as or smaller than the line width. The dashed rectangle encloses the area depicted in the zoom-in on the top-right corner
