Over at the ISOGG Facebook group, Rich Capen asked if it would be possible for Double Match Triangulator to compare GEDmatch kits. Well, that spurred my interest to see if I could. My uncle’s Chromosome Browser Results (CBR) file at FamilyTreeDNA is very big because he is Ashkenazi. I just downloaded a new ...

I’ve released a beta of what will be version 1.2 of DMT. 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 Innovator Showdown coming up, I wanted to get some major enhancements in. ...

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 ...

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, ...

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 www.beholdgenealogy.com/dmt. ...

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 ...

(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 ...

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 ...

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 ...

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 ...
