Authentication and Assessment of Contamination in Ancient DNA

Methods Mol Biol. 2019:1963:163-194. doi: 10.1007/978-1-4939-9176-1_17.

Abstract

Contamination from both present-day humans and postmortem microbial sources is a common challenge in ancient DNA studies. Here we present a suite of tools to assist in the assessment of contamination in ancient DNA data sets. These tools perform standard tests of authenticity of ancient DNA data including detecting the presence of postmortem damage signatures in sequence alignments and quantifying the amount of present-day human contamination.

Keywords: Ancient DNA; Contamination; DICE; Postmortem damage; Schmutzi; mapDamage2.0.
