What Happened to the 2017 Innovation Showcase Winners? - Part 4


Part 4 of a 5 part series

And third place went to ....


Quoting the news release:

Third Place Judges’ Choice Award ($26,000 cash and AWS credits), Louis Kessler, Double Match Triangulator, an app to help sort DNA matches into groups of relatives.

There are times in life when you realize that some people are just flat out smarter than you are, this is one of those times. I will let Louis Kessler describe the Double Match Triangulator, from his website DoubleMatchTriangulator.com:

Double Match Triangulator is an autosomal DNA analysis tool.

DMT combines segment match data of two or more people to find all the double matches and all the triangulations between them. This gives you information that can help you determine your common ancestors and how you are related to your DNA relatives.

What DMT Does:

DMT reads two or more segment match files that you can download from several DNA services. The process of looking for segments that overlap used to be a tedious one. DMT quickly and visually presents you with all the segments that overlap between two or more people and saves you the work of trying to discover the segments yourself. It produces Excel files with information and visual maps of the matches as well as an index of all the people you match to and how you match them.

Definitions:

·       A "Double Match" is where "Person A matches Person C" and "Person B matches Person C" on a segment. Only if "Person A also matches Person B" on the segment, then the segment is said to "Triangulate", otherwise the segment is a "Missing AB Match".
·       Double match segments that overlap form "Triangulation Groups". People in these groups could be sharing a common ancestor. If the double match also triangulates, then the segment of DNA may be from the common ancestor. Triangulation groups are your key to finding how other DNA testers are related to you.

In February, this year, DMT 2.0 was released.
