What’s GEDmatch?

GEDmatch is a free third party website, run by volunteers who have created a tool for those of us who have done an autosomal DNA test at the various DNA testing companies to talk to and share with one another without having to go and test at ALL the various DNA testing companies (see limitation below). Beyond this key benefit, it has many useful tools that allow us to compare and analyze our raw autosomal DNA.

Answer these 7 Questions to determine if GEDmatch is right for you

✔️ Have you done an autosomal DNA test?

✔️ Not ready to financially invest in testing at all the DNA testing companies?

✔️ Looking for a free interim solution to get instant access to more DNA matches without having to test at all the DNA testing companies?

✔️ Frustrated AncestryDNA doesn’t have a chromosome browser like all the other DNA testing companies?

✔️ Looking for more tools to analyze your DNA results and assess your DNA matches?

✔️ Prefer to email your matches rather than use the internal communication systems baked into the various DNA testing companies?

✔️ Want access to the DNA matches of your DNA matches?

If you responded with “oh yeah” to most of the questions above, then say hello to your new friend GEDmatch and keep on reading!

Should you consider using GEDmatch?

There are many reasons why you should consider using GEDmatch. Here are the top reasons:

More Autosomal DNA matches

Many of us long to connect with our DNA cousin matches, but the various DNA testing companies do NOT talk to one another. What if the DNA cousin match you are looking for is at the other DNA testing company you have not tested at? Now what? Does it mean you must now have to test at all the various DNA testing companies? Yes and no.

Ideally, yes, because unlike you, some of the DNA cousin matches you are longing to connect with have never heard of GEDmatch and/or have no idea how to upload to it.

For those who have uploaded to GEDmatch, you can save yourself some cash or take your time until you are able to invest testing at all the various DNA testing companies.

Chromosome browser

Did you test at AncestryDNA? Yes? Well, did you know they don’t offer a chromosome browser? Don’t fret, ’cause by uploading your raw autosomal DNA data file from AncestryDNA to GEDmatch, you now have access to a chromosome browser and can begin evaluating your shared segments with your DNA matches. Yehawwwwwwwww!

[Hold on!

You: Huh? Chromosome browser? Whatever. No biggie. I can live without it. Who needs a chromosome-browser-thing-ma-bob anyhow.

Me: Ummmmm, I’ll tell ya who. Anyone who is serious about trying to figure out how they are connected to a bunch of DNA cousins clumping up on the same segments, that’s who.]

Communication

The only way to communicate with our DNA matches is to use the internal messaging systems at the various DNA testing companies, which can be challenging. Some matches are slow to respond or worse, non-responsive and you can’t help but wonder if you had their email address and were able to directly email them, you’d have a better response rate. But, you’re stuck with those internal messaging systems. Well, not anymore because GEDmatch provides an email address per DNA file uploaded. It’s now easier to engage with your match as you now have their email address.

Useful tools

GEDmatch has many useful tools that allow us to compare and analyze our raw autosomal DNA (matching, chromosome browser, phasing, admixture calculators and other tools). How to get started using GEDmatch is covered in a video below.

The pros, cons and limitations of GEDmatch.

Here are some of the pros, cons and limitations of using GEDmatch:

Pros

• increases your chances of meeting DNA cousins who have tested at other DNA testing companies (see limitation below)
• saves you money, as you don’t need to test at ALL the DNA testing companies to get more possible matches (see limitation below)
• no fee is charged to start using it (but do consider donating and/or gaining access to tools not available in the free version)
• attracts people who tend to be more serious about genealogical research
• a chromosome browser for the AncestryDNA testers
• another way to communicate with your DNA matches by way of an actual email address

Cons

• not the “prettiest” website (keep in mind it does a great job of filling a void and it is run by generous volunteers)
• your email can be seen by anybody who shares your DNA or has gotten access to your kit number and many of them do not blur out nor keep your email confidential when sharing with others

Limitations

Not everyone who tested at the various DNA testing companies have uploaded to GEDmatch! So what? If your goal is to get the most possible matches, then you will have to test at all the various DNA testing companies.

How to upload to GEDmatch

Watch the 7 minute video below to learn how to upload your raw autosomal DNA data file to GEDmatch. It’ll walk you through a simple 3 step process:

Step 1 – register for a GEDmatch account

Step 2 – download your raw autosomal DNA data file from the DNA testing company

Step 3 – upload your file to GEDmatch

All of the popular DNA testing companies are covered in this short video (AncestryDNA, 23andMe* and Family Tree DNA).

*effective August 2017, 23andMe is using a new chip and if you tested thereafter you will NOT be able to upload to the legacy GEDmatch, BUT you can upload to GEDmatch Genesis.
