The Allen Ancient DNA Resource (AADR) is a curated compendium of ancient human genomes, aiming to provide an up-to-date, standardized version of published ancient human DNA data. Since its inception in 2019, the AADR has grown to include data from over 10,000 individuals, with a focus on uniform curation and version control. The resource addresses the challenge of diverse data formats and metadata by consolidating and standardizing ancient DNA data, making it accessible for researchers to download, analyze, and reference. The AADR includes data from various regions, with a significant proportion from Europe and Russia, and increasing contributions from East Asia and Africa. The resource is available at Harvard Dataverse and consists of three standard files in EIGENSTRAT format, along with a rich annotation file. The AADR undergoes regular validation and curation to ensure data quality and completeness, and it integrates modern human data from projects like the 1000 Genomes Project and the Human Genome Diversity Project. Researchers are encouraged to cite both the AADR paper and the original publications that produced the data.The Allen Ancient DNA Resource (AADR) is a curated compendium of ancient human genomes, aiming to provide an up-to-date, standardized version of published ancient human DNA data.
