Abstract

Summary: Ancient DNA extracts consist of a mixture of contaminant DNA molecules, most often originating from environmental microbes, and endogenous fragments exhibiting substantial levels of DNA damage. The latter introduce specific nucleotide misincorporations and DNA fragmentation signatures in sequencing reads that could be advantageously used to argue for sequence validity. mapDamage is a Perl script that computes nucleotide misincorporation and fragmentation patterns using next-generation sequencing reads mapped against a reference genome. The Perl script outputs are further automatically processed in embedded R script in order to detect typical patterns of genuine ancient DNA sequences. Availability and implementation: The Perl script mapDamage is freely available with documentation and example files at http://geogenetics.ku.dk/all_literature/mapdamage/. The script requires prior installation of the SAMtools suite and R environment and has been validated on both GNU/Linux and MacOSX operating systems.

  • Previous studies have reported lower error rates and higher extension termination rates for Pfu-based polymerases (such as Phusion) compared to Taq-based and other uracil-tolerant polymerases.

    “Previous studies have reported lower error rates and higher extension termination rates for Pfu‐based polymerases (such as Phusion) compared to Taq‐based and other uracil‐tolerant polymerases (Heyn et al., 2010; Ginolhac et al., 2011; Wales et al., 2014).”

    From Successful enrichment and recovery of whole mitochondrial genomes from ancient human dental calculus (2016) · cites this paper as Ginolhac et al., 2011

    In the 'mapDamage options' section (page not supplied), the paper reports fewer cytosine-to-thymine misincorporations in a Phusion-amplified ancient-DNA library than in one amplified with high-fidelity Taq. That supports a narrower claim about damage-related misincorporations, not general polymerase error rates. Our copy does not report extension-termination rates or comparisons with other uracil-tolerant polymerases. (LLM, conf=0.87)

  • The authenticity of the human reads obtained from archaeological dental calculus and dentine was assessed by examining damage patterns typical of ancient DNA.

    “The authenticity of the human reads obtained from archaeological dental calculus and dentine was assessed by examining damage patterns typical of ancient DNA (Briggs et al., 2007; Ginolhac et al., 2011; Jonsson et al., 2013).”
  • Authentic ancient DNA exhibits characteristic damage including short DNA fragment lengths, a high rate of cytosine deamination at the termini of DNA fragments, and an enrichment of purine bases at DNA breakage sites.

    “Briefly, authentic ancient DNA is known to exhibit characteristic damage that includes short DNA fragment lengths, a high rate of cytosine deamination at the termini of DNA fragments, and an enrichment of purine bases at DNA breakage sites.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
