All My GEDmatch Articles

Apr7

GEDmatch is one of my favorite sets of genetic genealogy tools but it can be hard to get started with. I have done many presentations over the years attempting to help people master the basics there, most recently for Family Tree University (click here). Plus I wrote a GEDmatch Basics article for their magazine (click here) which explains all the column headings on the one-to-many report. [UPDATE 15 Apr 2024: Click here for the interview I did for the FTU podcast.]

Over the past 12 years I have written many posts about GEDmatch, most of which are still useful. So I decided to make a new tag – GEDmatch tools – which brings up just my posts that explain a specific tool. Now I can see which tools I still need to write about!

Here is the list of my articles in reverse chronological order (click any title to go to that post):

What’s new at GEDmatch and i4GG

Jan25

Every year genetic genealogists gather in San Diego in February for the i4GG conference founded by CeCe Moore and Dr. Tim Janzen. This year is the tenth anniversary and I am honored to be one of the presenters again. Click here for the i4GG web site.

In past years I have talked about the new features at GEDmatch. In 2022, this was a particularly dense lecture. (click here for the slides), as there were so many new and enhanced features. Clustering was taking the community by storm and GEDmatch has two versions of that, one of which even includes tree building.

{UPDATE 9 Feb 2024] My talk for i4GG this year is about how to use Ethnicity to solve DNA cases. This year, I will talk about GEDmatch yet again, but as there are fewer new features, I will include some of the ways that site has helped me solve DNA puzzles.

One nice new feature is that the site now sends you an email when you have a new match. You can select both the frequency of those emails and the match size which triggers an email.

Whenever I get a new match on the One-to-Many, the first thing I want to see is who else they match among my relatives, so it has always puzzled me why they did not include a button to do that. Needless to say this was a feature I requested. Now it is finally here! There is a column called ICW tool which has the word Match which when clicked takes you to the function People who match both, or 1 of 2 kits with the kit numbers filled in, ready to use.

My talk about GEDmatch and more about GEDCOMs

Jun6

Finally! The video of the GEDmatch basics talk I did on May 26 for Verogen is now available. Best to view it full screen at youtube in order to see the images well.

Click here for the slides for that talk

GEDmatch, a DNA tools site, was originally created to compare GEDCOMs, a function you can still use it for. A GEDCOM is a plain text file of your family tree formatted so that any genealogy program can understand it. Click here for the wikipedia entry explaining this in more detail.

In my talk I emphasized that it is best to upload a privatized GEDCOM with no more than 10 generations of ancestors then connect it to the DNA test for that person. This will help you use the relative matching tools. I promised in the presentation to explain how to create a GEDCOM. So here are a few of the many ways.

A Really Basic Approach to Using GEDmatch

Feb18

GEDmatch.com is about to get a face lift. Many have complained that it is not intuitive and does not offer enough help for a newcomer. The new site hopes to correct some of that; I am helping with the beta test now; it sure is prettier!

Why use GEDmatch and what is it? Well it’s a free 3rd party site of tools where you can upload your DNA test results and compare them with those from people who have tested at other companies. Plus there are many analysis tools, some available nowhere else. These include GEDCOM (family tree) comparisons, including yours to your DNA matches.

Recently I gave a talk for the Family History Fanatics at their Winter of DNA conference where I demonstrated how to use GEDmatch without worrying about segments. An approach that gets a lot out of the site without having to be a geek like me. The slides are here: https://slides.com/kittycooper/gedmatch-basics-2021

Here is a step by step of that very basic approach as outlined in the syllabus for my FHF presentation

1. Create a User ID and Upload a DNA raw data file, aka a “kit”

Click the image above to go to the video from Andrew Lee, of FHF, which shows you how to create a user id and upload your DNA raw data to GEDmatch.

Or read this blog post of mine which also has links to my other GEDmatch posts

2. Once Logged in, your Dashboard Page is not Intuitive

The tools are in the right hand column and the resources you have uploaded are listed on the left. You can upload more than one DNA kit and multiple GEDCOMs. There is a help section on the top right.

This post from Jim Bartlett is a useful explanation of the home page, as is my basics post listed above.

And here is what my beta test Dashboard looks like, an improvement? I think so.
