Double Match Triangulator 1.1.99 - Blog entry by lkessler - 18 Oct 2016

I’ve released a beta of what will be version 1.2 of DMT. You can get it here: It has all the new functionality. I just haven’t updated the help file yet. Once the help file is updated, I’ll re-release it as 1.2. With the deadline for the RootsTech ...

DMT Entered in Innovator Showdown @RootsTechConf - Blog entry by lkessler - 27 Sep 2016

Lots has happened in the past few weeks. I’ve booked my flights, hotel and registered for RootsTech 2017 in Salt Lake City from Feb 8 to 11. I was there in 2012 and 2014 so its been a while and I’m looking forward to renewing some acquaintances and meeting other genealogy software developers, geneabloggers ...

Triangulation and Missing a-b Segments - Blog entry by lkessler - 30 Aug 2016

First to reassure you, I am back working towards finishing Behold Version 1.3. But I do have to put up this post before I forget about it. Two days ago, I  announced my free Double Match Triangulator program on the International Society of Genetic Genealogy (ISOGG)’s Facebook page. It is a closed group, ...

Double Match Triangulator (DMT) 1.0.1 - Blog entry by lkessler - 21 Aug 2016

I’ve now released my new freeware program to provide a new view to help people analyze their autosomal DNA matches from FamilyTreeDNA. It is called Double Match Triangulator. I actually released version 1.0 a couple of days ago, but fixed a bug and version 1.0.1 is available at ...

Writing Freeware (Double Match Triangulator) - Blog entry by lkessler - 17 Jul 2016

Most people might think releasing a freeware program is easy. Just write it and make it available. Right? Well, there’s a bit more in it than that. When I came up with the idea for Double Match Triangulation of autosomal DNA using the chromosome match files produced by FamilyTreeDNA, I knew I’d need a ...

Misleading Double Entries in FamilyTreeDNA Data - Blog entry by lkessler - 7 Jul 2016

(This article was revised 11 Aug 2016 to fix some incorrect statements) Be careful if you’re triangulating at FamilyTreeDNA. I just found out they can match twice on a segment. If you look in your Chromosome Browser Results file which is downloadable from the Chromosome Browser page, you may find matches ...

Help Needed for DMT - Thank You! - EAST Part 3 - Blog entry by lkessler - 2 Jul 2016

I have the basics of my Double Match Triangulation program working, but before I can release it to the world (as freeware!), I must put it through its paces and test it with some real data and ensure that it will correctly analyze and display the data and relationships. Since I’ve only DNA tested my 93 year ...

FamilyTreeDNA’s Chromosome Match File - Blog entry by lkessler - 25 Jun 2016

My DMT (Double Match Triangulation) program that will make use of FamilyTreeDNA chromosome segment match data is nearing completion. As I was looking through some of the results it was producing, I got an unexpected surprise. I found there were some people my uncle Harry matched to in his Chromosome Browser ...

EAST Part 2 - Double Match Triangulation - Blog entry by lkessler - 14 Jun 2016

In Part 1, I gave you a flavour of the mass-triangulation that I am doing, which I called EAST: Extreme Autosomal Segment Triangulation. Triangulation is a technique to determine what parts of your DNA come from what ancestors. That will help you determine how your matches are related to you. What is new about ...

Extreme Autosomal Segment Triangulation (EAST) - Part 1 - Blog entry by lkessler - 12 Jun 2016

You’ve heard of extreme sports. Well this, I think, is the genetic genealogist’s equivalent. In DNA or Bust, I told about getting my 93 year old uncle’s DNA analyzed. Our Endogamous Ashkenazi heritage layed 7,017 matches upon us. That was one month ago. Since then, FamilyTreeDNA have updated their ...
