I'm very excited to announce the following. It's something I've been wanting every time I see a distant cousin's DNA test connected to one of my ancestor's profiles (which is becoming more and more common -- 3.3 million of our profiles have them).
You will now see "[compare]" links next to GEDmatch kit IDs on profiles and DNA Ancestor Confirmation Aid pages such as Roberts-7085/899.
For your own Ancestor Confirmation Aid page, click here and then select the "DNA Confirmation" button.
If you select or enter two GEDmatch IDs you can go directly to a one-to-one comparison on GEDmatch with one click. (This also works for Ysearch and Mitosearch IDs. This capability isn't new, but we integrated the user interface for it.)

This is another step forward in our growing relationship with GEDmatch. And there's more on the way. John Olson, John Hayward, and Curtis Rogers are constantly improving GEDmatch's capabilities and we're working together to utilize their advanced genetic genealogy tools for our mission to grow an accurate single family tree.
In particular, GEDmatch is in the process of restructuring and improving their Multi-Kit analysis. And they're working on integrating the new Genesis kit IDs into their main database. When these changes are done, GEDmatch will enable WikiTree members to select more than just two kits at a time for comparison. This will be a major advance for triangulation, and for genetic genealogy in general, I'd say.
Onward and upward,
P.S. As with many of our DNA features, this would not have happened without Peter Roberts. It's to his credit, from start to finish. The last pieces fell into place at the FTDNA conference down in Houston. Peter, Mags Gaulden, and a whole contingent of other WikiTreers were evangelizing for the importance of the single family tree in genetic genealogy. Face-to-face interactions in the small community of advanced genetic genealogists really make a difference. Peter's discussions with John Olson there got the last pieces into place for these comparison links.
