AutoSegment Split
There’s nothing that makes you feel older than when you start talking about how you used to do things “back in the day.” The problem with genetic genealogy is that back in the day isn’t really that far back. Since the advent of consumer DNA testing 25 years ago, great strides have been made to…

AutoKinship
AutoKinship is a Tier 1 tool at GEDmatch. Unlike Autotree (1), it does not require GEDcoms to be useful. AutoKinship creates possible family trees based on the amounts of DNA that the matches share with each other, which means that it doesn’t require any of those matches to have trees associated with their accounts. Like…

AutoTree at GEDmatch
AutoTree isn’t actually a standalone tool, so technically, this post is the sequel to my AutoCluster post (1). AutoTree searches the GEDcoms of your matches to see if it can find an MRCA for each cluster. Check off the AutoTree box to get AutoTree results when using the AutoCluster tool. Once you get your results,…

AutoSegment at GEDmatch
Now that I’ve explained the clustering (1)and triangulation (2)tools at GEDmatch, the scene is set to introduce a tool that I think of as the baby of these two tools. AutoSegment is a Tier 1 tool which you can find in the sidebar or dropdown menu. You enter a kit number and the number of…

Clustering at GEDmatch
A new tool recently came out at GEDmatch, and I wanted write a blog post about it so I could understand it better. I realized, however, that I had never written about GEDmatch’s clustering tool, which is useful for understanding how this new tool works. I’ve talked about clustering (1) before, when it was a…

Triangulation, Part 5
I didn’t think there was anymore to say about triangulation, and then I was working on some presentations on various Gedmatch tools and noticed that there is now a triangulation tool. This tool kind of makes my original post (1) moot, but I’ll keep it up there because it’s a good explanation of what triangulation…

Welcome to the Matrix
If you’re expecting to choose between a red and blue pill right now, you’re going to be sorely disappointed. But if you’re looking to understand how to read a matrix, you’re in the right place! First, how do we create a matrix? This can be done easily in GEDmatch (1), regardless of whether or not…

Gedmatch Basics, Part 2
This is the sequel to my post Gedmatch Basics, Part 1. In order to understand the things that we’re going to talk about, you’ll need to understand the things mentioned in that post, so if you haven’t read it yet I suggest you do so. Since I first wrote this post, a lot has changed…

Opting In
I’ve been meaning to write this post for a long time now – since April 2018, when the Golden State Killer case changed the genealogy world forever. Since then, genealogy has been combined with law enforcement efforts to find the perpetrators of violent crimes, as well as to identify unknown remains. Unidentified remains are often…

DNA and privacy
There’s been a lot of news articles and news show segments about DNA testing and privacy, and we all know I feel about that: What I want to do here is help people make an informed choice about DNA testing, and that means facts, not fearmongering. There are three basic concerns when it comes to…
