Double Match Triangulator 3.0 Released - Tue, 1 Oct 2019

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 a lot new and improved here.

• An MRCA (Most Recent Common Ancestor) column has been added to the People file, allowing you to enter the MRCA for each person that you know.
• The process of segment matching and assignment of ancestral paths to segments and matches is now automated in an expert-system manner that mimics what a person would do map their chromosomes.
• You can now select the minimum cM of the matches that you want DMT to include in its analysis.
• You can now run DMT with only Person A to get the listing of Person A’s matches and people.
• DMT now handles all the new segment match file formats from the various companies.
• The Map page, People page and Log file all have extensive revisions.
• DMT outputs a dnapainter csv file that can be uploaded to www.dnapainter.com.
• Now uses conditional formatting extensively in the Excel files, so most of the formatting should move when the data is copied and pasted or sorted.
• Now can filter all matches to a minimum cM.
• Calculates and uses all inferred matches.
• Clusters people into their primary ancestral lines.
• Does parental filtering if one or both parents have DNA tested.

This is what the DMT program looks like. It is this one window:

This is what DMT’s Map page looks like, listing every segment match:

This is what DMT’s People page looks like, listing every person matched:

Here’s an example of a upload to DNA Painter from a DMT file;

There are many great tools available now for genetic genealogists who are interested in using their DNA to help them figure out their connections to relatives.

With version 3.0 of DMT, I’ve now made available a tool that automates segment matching, triangulation and chromosome mapping. It’s a bit different from all the others and it should give you new and different insight into your DNA matches.
