Unleash your DNA cousins

Genetic Affairs offers the AutoCluster, AutoScan and AutoTree tools. AutoCluster groups together your DNA matches into clusters of matches that most likely descend from common ancestors. AutoScan performs regular updates for different DNA companies and AutoTree identifies common ancestors and reconstructs trees for Ancestry DNA matches.

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.

Example 70cM - 400cM matches

Example 30cM - 400cM matches

Example 5 combined profiles

AutoTree - automated tree reconstruction

AutoTree compares Ancestry 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 currently only available for Ancestry profiles.

Example 50cM - 600cM matches

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.

How does a typical e-mail update look like?

After setting an update interval (daily, weekly or monthly) for a certain profile, a first search is performed to obtain all current genetic matches for that profile. If this search is successful, a confirmation email is send. The body of this email contains the best 20 matches as well as an attachment that holds all genetic matches for your account (for AncestryDNA, we provide all cousins up to and including fourth cousins).
A typical email containing updates is placed underneath:

"Hello Dennis Payne,

Placed underneath are the individual update(s):
Joe Payne: A 23andme search has been performed and identified a total 1118 DNA matches. Of the 2 new DNA matches, one match is a DNA match that is predicted as 4th Cousin or closer and is listed underneath.

M. Haywire shares 4 DNA segments (0.48%, approximately 34.6 cM ) and is a predicted 3rd Cousin

Dennis Payne: An Ancestry search has been performed for Dennis Payne. Of the 46 new DNA matches, one match is a DNA match that is predicted as fourth cousin or closer and is listed underneath.

Keith Smith shares in total: 39.1 cM and is a predicted fourth cousin with a confidence value of 92.4%. Last, Ancestry has identified 32 other DNA matches in common (one of these common matches is actually one of your profiles: Mom of Dennis Payne)."
