After 10 months of hard work, I have finally released DMT 3.0. You can download it from www.doublematchtriangulator.com. (It is a Windows program. My apologies to Mac or Unix users) All purchasers of DMT get a lifetime license. All updates including this one are free for past purchasers. There’s ...

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 ...

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 ...

This is my first blog post in over 2 months. The reason is that I have been working very hard trying to finish Version 3 of Double Match Triangulator. Every thing I’ve been doing with it is experimental, and there’s no model to follow. So it’s tough to get it just right. I started the documentation of the ...

Although I don’t use Family Tree Maker (FTM), per se, I am very interested in its capabilities and syncing abilities. FTM along with RootsMagic are the only two programs that Ancestry have allowed to use the API that gives them access to the Ancestry.com online family trees. Therefore they are the only two ...

In my last post, I was able to create a raw data file from the Whole Genome Sequencing (WGS) BAM file using the WGS Extract program. It seemed to work quite well. But my previous post to that: WGS – The Raw VCF file and the gVCF file, I was trying to see if I could create a raw data file from the Variant ...

I was wondering in my last post if I could create a raw data file that could be uploaded to to GEDmatch or DNA testing company from my Whole Genome Sequencing (WGS) results. I was trying to use one of the Variant Call Format (VCF) files. Those only include where you vary from the human reference. So logically ...

As I noted in my last post, Whole Genome: The VCF File, Part 2, the SNP VCF (Variant Call Format) file that Dante Labs gives tester of WGS (Whole Genome Sequencing), does not quite have everything that is needed to generate a raw data file that can be uploaded to various DNA sites for people matching. ...

A couple of months ago, I compared my VCF file to my DNA test results. The Variant Call Format (VCF) file is given to you when you do a Whole Genome Sequence (WGS) test. That test finds your DNA values for your whole genome, all 3 billion positions, not just the 700,000 or so positions that a standard DNA ...

I saw a post on Facebook trying to compare the number of relative matches a person hade at different DNA testing companies. Here's my results with my endogamy: Note that there are a few things to consider when you or anyone else does a comparison of your number of DNA matches. A few companies only give ...
