Gedmatch Tier 1 Step 1

Using GEDmatch (The Triangulation Tool)

The previous article in this series is Using Genome Mate (Add confirmed segments to chromosome map).

As explained in my earlier post, Using Genome Mate (Identify triangulated groups and confirm segments), we now have an understanding of the basic principals of triangulating DNA segments, and know how to manually go through our match data and identify triangulated groups. In this post, I will show how to use the GEDmatch Triangulation tool to automatically identify the triangulated segments you share with your 400 closest matches at GEDmatch and then easily import the triangulated segment results from GEDmatch into Genome Mate.

Using Genome Mate (Add confirmed segments to chromosome map)

The previous article in this series is Using Genome Mate (Identify triangulated groups and confirm segments).

In following the steps that have been previously outlined, we now know how to identify triangulated groups and confirm the segments within a triangulated group. This post will show the steps to add these triangulated segments to our chromosome map.

Genome Mate Triangulated Segments Post Background Screen Shot

Using Genome Mate (Identify triangulated groups and confirm segments)

The previous article in this series is Using Genome Mate (Importing/Updating the email addresses of your matches from GEDmatch).

In following the steps that have been previously outlined, we now have imported a sizable amount of data from GEDmatch into Genome Mate. This post will show how to begin working with this data to identify groups of triangulated segments. The process of identifying triangulated groups can be very time consuming, and like genealogy itself, is something that is never ending. The concepts of identifying triangulated groups are fairly simple to grasp, but there is no shortcut to taking the necessary time to work through and analyze your DNA data. As one leading genetic genealogist, Dr. Blaine Bettinger (, summed it up so accurately, “Finding genetic matches is easy, but finding the common ancestor from whom we inherited a segment [of] DNA is very hard.”

Using GEDmatch Step 22

Using Genome Mate (Importing/Updating the email addresses of your matches from GEDmatch)

The steps we have used to import GEDmatch segment data into Genome Mate have not imported the email addresses of our matches from GEDmatch. Importing these email addresses is done as a separate import. This post will show the email address import process, step by step. It’s also a good idea to use this same import process from time to time to update the email addresses of your imported matches in Genome Mate, in case someone has changed the email address associated with their kit at GEDmatch.

Steps to DNA Matching and Chromosome Mapping with GEDmatch and Genome Mate

For awhile now, I’ve planned to write a summary of the steps to using GEDmatch and Genome Mate for chromosome mapping. Based on some great feedback and suggestions from Roberta, one of my blog readers, I’m going to go ahead and post this summary now, instead of waiting until I have completed the step by step guides for the entire process. My hope is this will help people to begin making the most efficient use of their DNA data right away, as well as letting people know what topics I will be covering next in the process. As I continue to add the rest of the step by step guides, I will update this post by adding the links to the new guides after I have completed writing them. In addition, I hope to keep evolving this post by incorporating new methods and tools that may become available for working with one’s genealogical DNA data.

Using GEDmatch - Phasing Step 2

Using GEDmatch Part 6 (The Phasing Tool)

The previous article in this series is Using GEDmatch Part 5 (Alternate To Triangulation Tool).

Twice within the past week, I’ve come across situations where the GEDmatch phasing tool would be very likely to help solve someone’s genealogical mystery. It seems some people may not be aware of this extremely useful, yet easy to use, tool. Therefore, I thought it would be a good idea to write a few words explaining a bit about what the phasing tool does, and what the benefits of using it are, as well as show the very quick and simple steps to using the tool.
