Using Goran Runfeldt’s Family Finder Segment Triangulator Chrome Extension

This is the second tutorial on Goran Runfeldt’s Family Finder Segment Triangulator Chrome extension. It is a walk-through of the basics of using the tool on the Family Tree DNA website.

Before you start, you need to have a Family Finder account at Family Tree DNA, the Chrome web-browser installed on your computer, and the Family Finder Segment Triangulator Chrome extension installed.

Step 1

Go to the Family Tree DNA Sign In page. Fill in your kit number and password, then click the SIGN IN button.

You will see that a dnagen tools button is now on the page. Select at least two matches from the match list.

Step 4

Once you have selected matches, select the Triangulator option from the dnagen tools menu.

Step 5

The Triangulator pop-up window opens with the Triangulated Segments tab open. The Minimum segments length is set to 5 cM by default. I strongly suggest changing this to 10 cM or 15 cM if you are from either an endogamous population or have frequent cousin marriage in your pedigree.

Each triangulated DNA Segment is shown with information and a picture that shows the area that did and the area that did not triangulate.

Step 6

The relationship range between each person in the triangulation is on the Relations tab. At Family Tree DNA, these relationships are: Immediate, Close, Distant, and Speculative.

In the next tutorial in this series, I will show how to download an CSV file of the matching segment information from a triangulation and open it in Google Spreadsheets.
