Part 4 of a 5 part series
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.
