Using DMT, Part 1: My 23andMe Data - Blog entry by lkessler - 17 Oct 2019
I am going to show you how I am using Double Match Triangulator, and some of the information it provides, at least for me. My own DNA match data is difficult to analyze. I come from a very endogamous population on all my sides that originates in Romania and Ukraine. The endogamy gives me many more matches than ...

DMT 3.1 Released - Blog entry by lkessler - 16 Oct 2019
I’m working on a series of articles to show how I am using the new 3.0 version of Double Match Triangulator to analyze my own segment match data. As much as I’d like you to believe that I’ve developed DMT for the good of genetic genealogists everywhere, I humbly admit that I actually developed it so ...

The GEDCOM 5.5.5 Initiative and Making It Work - Blog entry by lkessler - 6 Oct 2019
It’s been 35 years since GEDCOM 1.0 was released to the genealogical software development community in 1984. It’s been 20 years since GEDCOM 5.5.1, the last official specification by FamilySearch was released on October 2, 1999. Five days ago, October 2, 2019, the gedcom.org website was renewed containing ...

It Took a Lot of Effort to Get to DMT 3.0 - Blog entry by lkessler - 5 Oct 2019
I’m cleaning up my directories after over 3 years of development of Double Match Triangulator. When I released Version 1 of DMT back in August 2016, I had it write information about the run to a log file, primarily so that I could debug what was going on. But I realized it is useful for the user as it could ...

23andMe’s Family Tree Beta - Blog entry by lkessler - 23 Sep 2019
Someone on Facebook reported a new feature at 23andMe and I couldn’t wait to try it. This 23andMe beta “auto-builds” your family tree from your DNA connections with other customers. They aren’t the first to try something like this. Ancestry DNA has ThruLines, which uses your tree and your DNA ...

The Life and Death of a DNA Segment - Blog comment by lkessler - 22 Aug 2019
Ahh. Now I see what you're trying to do. You're taking the two pieces of the 15 cM segment, and deciding that if one was only 5 cM, then it wouldn't match anyone because the smaller side wouldn't reach the threshold that the company calls their minimum match.Yes. That's entirely possible and may be the reason ...

The Life and Death of a DNA Segment - Blog comment by lkessler - 21 Aug 2019
Jonathan: I don't understand your logic why a 6 cM limit means that the 15 cM wasn't born in some ancestor, but got longer. It's always a recombination that creates a new segment. Whether it or parts of it are filtered out by the company doesn't seem relevant to me because the filtering is only done in the DNA ...

The Life and Death of a DNA Segment - Blog entry by lkessler - 19 Aug 2019
There’s a bad rumor going around that segment matches, especially for small segments, can be very old. I’ve heard expectations that the segment might come from a common ancestor 20 generations back or even 30, 40 or more. And that’s said to happen even if you have a fairly large 15 cM segment. Part of ...
