Double Match Triangulator is an autosomal DNA analysis tool for Windows.DMT combines segment match data of two or more people and automates the analysis of your segment match data, combining it with common ancestor data that you provide.
This gives information that could help you determine how you are related to your DNA matches.
DMT can accept data from FamilyTreeDNA, 23andMe, MyHeritage DNA, or 免费加速器油管.
DMT won 3rd Place at the 2017 RootsTech Innovator Showdown.

DMT combines segment match data of two or more people to find all the double matches and segment triangulations they share. Using known common ancestors of known relatives, DMT determines ancestral paths to indicate the common line that the DNA passed through and it organizes these into triangulation groups for you. DNA relatives who match in a triangulation group may have a common ancestor along or beyond the ancestral path who passed this segment to to all the people in the group. The assignment of ancestral paths to segments of your DNA is known as Chromosome Mapping.The determination of triangulation groups has for a long time been a very labour intensive manual procedure that few people have accomplished. DMT automates this for you and internally does this determination for you, and makes this type of analysis available to anyone.
DMT reads two or more segment match files that you can download from several DNA services. The processing of "Double Matching" that DNA uses is able to find every segment triangulation that two people share with a third. A triangulating segment is a indication that the matching segment may be passed down from a common ancestor of the three people.
The DMT main window looks like this:
DMT lets you enter the match file for Person A and the match file for Person B or a directory containing Person B match files to compare Person A with.
The DMT Map page looks like this:
Double Match Triangulator delimits triangulation groups helping you identify segments of Person A's DNA that may come from a particular ancestor.
The DMT People file looks like this:
DMT can also create a file that can be uploaded to Jonny Perl's DNA Painter. The result in DNA Painter looks like this:

Double Match Triangulator requires Windows and has been tested back to Windows 7. It will produce formatted Excel files in .xlsx format that can be read by most spreadsheet programs.
Mac users: Sorry but there is only a Windows version. If you have Excel on your Mac, you can still read the Excel files that DMT produces. You can ask one of your DNA relatives to run the program and send you the Excel output files. If you want to run it yourself, I've been told that DMT "runs like a charm on a Mac using Crossover or some other software that lets you run Windows applications." But even better, I've also been told that "DMT runs smoothly with PlayOnMac" which is a free, simple to use emulator for the Mac that doesn't need a reboot or a Windows license.
Unix users: DMT should run under Wine.
上youtube加速器 I have been told that on Windows, LibreOffice works better with DMT files than OpenOffice. The latter is poor at handling large Excel files. Google sheets will also open DMT files.
DMT works with segment match information. Here's the download instructions for:
- Family Tree DNA
- 23andMe
- MyHeritage DNA
- GEDmatch
