Unleash your DNA cousins

Genetic Affairs offers the AutoCluster tool which groups together your DNA matches into clusters of matches that most likely descend from common ancestors. AutoCluster and AutoTree can help in the identification of unknown ancestors (for instance an unknown great grandfather) or assist persons with unknown parentage to their birth families (e.g., adoptees or donor-conceived persons)

AutoCluster - automated clustering of shared matches

AutoCluster organizes your matches into shared match clusters that likely represent branches of your family. The AutoCluster analysis is available for profiles from 23andme, FamilyTreeDNA and AncestryDNA and the results are presented in an interactive visualization.

AutoTree - automated tree reconstruction

AutoTree compares trees to find common ancestors (MRCAs) and reconstructs a tree. AutoTree works for persons with unknown parentage to their birth families (for instance adoptees or donor-conceived persons) as well as people that have linked their DNA profile to a tree. The AutoTree analysis is available for Ancestry and FTDNA profiles.

Frequently Asked Questions

What is AutoCluster?

AutoCluster is an analysis provided by Genetic Affairs that downloads, given certain user defined thresholds, your matches together with their shared matches. Next, we perform a clustering analysis which groups together DNA matches that have a similar shared matches profile. These groups of DNA matches are likely to have a common ancestors. It's comparable with the Leeds method of Dana Leeds but much faster and more comprehensive. MyHeritage decided to take a license on AutoCluster in the beginning of 2019. Theirnice blog post about their implementation contains a nice explanation of AutoCluster.

How does a typical AutoCluster result look like?

The analysis is started after setting the cM thresholds for a given profile. An email will be send to you after approximately 15-20 minutes. If all went well, this email will contain three zipped attachments. The first attachment contains a compressed table with the downloaded DNA matches. The second attachment will contain a compressed spreadsheet version of the AutoCluster result. The third and last attachment contains the compressed HTML

How am I informed concerning new DNA matches?

Information concerning new matches is mailed to your email address. In addition, the information is available after you login to Genetic Affairs in the form of notifications.
