Open access

Abstract

BACKGROUND: High-throughput DNA sequencing technologies are generating vast amounts of data. Fast, flexible and memory efficient implementations are needed in order to facilitate analyses of thousands of samples simultaneously. RESULTS: We present a multithreaded program suite called ANGSD. This program can calculate various summary statistics, and perform association mapping and population genetic analyses utilizing the full information in next generation sequencing data by working directly on the raw sequencing data or by using genotype likelihoods. CONCLUSIONS: The open source c/c++ program ANGSD is available at http://www.popgen.dk/angsd . The program is tested and validated on GNU/Linux systems. The program facilitates multiple input formats including BAM and imputed beagle genotype probability files. The program allow the user to choose between combinations of existing methods and can perform analysis that is not implemented elsewhere.

  • We excluded libraries with X-contamination estimates greater than 1.5%.

    “we excluded libraries with X-contamination estimates greater than 1.5%32.”
  • The study evaluated each individual for evidence of authentic ancient DNA by limiting to libraries with a minimum of 3% cytosine-to-thymine errors at the final nucleotide, requiring X-to-Y-chromosome ratio characteristic of sex, >95% matching to mtDNA consensus, and <2% contamination for males.

    “We evaluated each individual for evidence of authentic ancient DNA by limiting to libraries with a minimum of 3% cytosine-to-thymine errors at the final nucleotide29, by requiring that the ratio of X-to-Y-chromosome sequences was characteristic of either a male or a female, by requiring >95% matching to the consensus sequence of mitochondrial DNA30, and by requiring (for males) a lack of variation”

    From Ancient DNA from Chalcolithic Israel reveals the role of population mixture in cultural transformation (2018) · cites this paper as [32]

    The citation is attached to the minimum 3% terminal cytosine-to-thymine error criterion. The ABBA-BABA section says transitions have high error rates in ancient genomes, but our copy does not give a 3% threshold or describe terminal-base errors as an authenticity test. Searches for those criteria found no supporting passage. (LLM, conf=0.74)

    Experimental — accuracy not yet measured
  • We assessed the quality of each library at the screening stage using three standard methods for determining ancient DNA authenticity: mitochondrial genome matching rate, C-to-T substitution rate, and X-chromosome contamination.

    “We assessed the quality of each library at the screening stage using three standard methods for determining ancient DNA authenticity.”

    From Ancient DNA from Chalcolithic Israel reveals the role of population mixture in cultural transformation (2018) · cites this paper as [32]

    The Results and discussion > ABBA-BABA section (page unavailable) describes filtering error-prone transitions when analyzing an ancient Denisovan genome, not screening libraries for authenticity. Searches for mitochondrial matching rates, C-to-T substitution rates, and X-chromosome contamination found no passage describing the three claimed methods. (LLM, conf=0.77)

    Experimental — accuracy not yet measured
  • Nuclear contamination in males was estimated using ANGSD, which compares mismatch rates between polymorphic sites on the X chromosome.

    “We next used ANGSD (v0.910) (41), which compares mismatch rates between polymorphic sites on the X chromosome to estimate nuclear contamination in males.”

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.
