Uploading Ancestry Dna Raw Data to Gedmatch
In this tutorial article, nosotros're talking about what is GEDmatch, how to upload your Deoxyribonucleic acid data from unlike Deoxyribonucleic acid testing services into GEDmatch, and explaining each function and how information technology tin can maximize your Deoxyribonucleic acid relative match. GEDmatch is one of the nearly pop tools to rail downwards family unit members and acquire about your family history. Using raw Deoxyribonucleic acid data that you can become from a genetic Dna testing kit kit from companies similar 23andMe or AncestryDNA, GEDmatch allows you to swoop deep into techniques used in genetic genealogy.
Although GEDmatch is an extremely powerful tool, there is quite a learning bend on how to apply GED lucifer effectively. Plus, keep in heed that GED friction match was recently purchased by a company that specializes in cold cases, law-breaking scene forensics, and uses the genealogy site to solve crimes. Follow along with the states to run across exactly how you can start using your raw Deoxyribonucleic acid data to enquiry your family history using GEDmatch!
What Is GEDmatch?
GEDmatch.com is a great family unit finder tool for people who are interested in finding your relatives for Costless. The website offers a suite of professional-form genealogy research tools that are not for the faint-of-heart!
GEDmatch got its roots when at-home consumer genetic DNA testing services started allowing users to download their raw information. With this genetic information, GEDmatch tin run a suite of statistical techniques to assistance yous fully sympathize your genetic heritage. Previously a non-profit company, the company was recently purchased past Verogen, Inc., a company that focuses on forensic evidence for law enforcement.
The database on the GEDmatch site was 1 of the beginning Dna databases that police force used to identify criminals - namely the Golden State Killer, who had avoided authorities for xl years! Verogen clearly valued GEDmatch'southward database, which was purchased along with the company. While site policy nonetheless allows you to "opt-out" of giving police force access to your data, having a database police enforcement can apply is clearly now a goal of the company. Even distant relatives with Deoxyribonucleic acid in the database can improve law enforcement matching and it makes genomics a useful tool for communicable criminals.
Is GEDmatch Condom?
Though GEDmatch started as free service allowing users to search for family members using their DNA information, the visitor was purchased past forensic company Verogen. Though the acquisition raised some concerns about user'due south DNA privacy and the transfer came with some bug, the company still provides users with the option of opting-out of constabulary enforcement searches. The company seems to be constant by this policy, every bit at that place was only one initial issue that resulted from a breach in the system. The outcome has been resolved, and no new reports of unwanted law enforcement access have been reported. Still, you lot may desire to know more virtually this incident to put your mind at ease.
In July 2020, the GEDmatch database was breached past hackers. As a result of this incident, the privacy controls on millions of user accounts were overridden. For about 3 hours, this alienation immune law enforcement agencies to encounter the data of millions of users who had not given their consent. While the site was shut down chop-chop and the privacy settings were restored, the breach started calls for GEDmatch to be more than transparent about their cooperation with law enforcement. For case, companies like 23andMe and Beginnings regularly publish reports that particular the times they were required to disembalm user information for legitimate legal reasons. This seems to have been a one-fourth dimension effect for GEDmatch, though caution is warranted if you do not want law enforcement officials to admission your private data without a search warrant.
How To Employ GEDmatch
How to Upload Data to GEDmatch
To begin, yous must register on GEDmatch.com.
Commencement, upload your Dna data from Dna testing companies like AncestryDNA. Later receiving the test results of your mutual ancestor, these companies allow you to download your ain raw DNA data and upload that elsewhere to access dissimilar information, similar GEDmatch.
List of companies whose raw data are compatible with GEDmatch (links to respective pages explaining how to download raw DNA data):
AncestryDNA (Ancestry.com)
23andMe

LivingDNA
Plus, GEDmatch now claims that "most other" visitor files are too uniform with their system!
Once yous've downloaded your raw information file, create a GEDmatch account and upload your raw DNA data. (We're writing a step-past-step guide on how to do this in another blog post). Annotation that it will take a few hours after uploading to come across your results. They don't notify y'all when it's set up — but you can check the "Kit ID", and if it says no kit number registered yet, you need to wait a little longer.
What is a kit number on GEDmatch?
After yous upload your raw DNA data for Deoxyribonucleic acid assay, the company volition assign you a kit number. Your kit number is a unique identifier tied straight to your DNA profile on GEDmatch. The kit number volition let you to share your profile with friends, allow them to find you on GEDmatch, and you can search other kit numbers to compare with.
Kit numbers take a standardized format, which as well allows you to run into where certain sources of data come from. This is useful if you are trying to track downwardly relatives, as you will go the best results if you submit a DNA data from the same source because the verbal same sites will be tested. This will give y'all the most authentic results.
DNA Application:
Once yous have added your Dna analysis, you are set up to begin exploring! Commencement on the right-hand side of the folio, under "Deoxyribonucleic acid Applications". This is where all of the gratuitous tools reside on GEDmatch. But click on each of the tools to get started. Call up: you volition need your kit number for most applications.
GEDmatch is commonly used by professional genetic genealogists for genealogy enquiry. The core features include:
- One-To-Many DNA Comparing Result: Helps you compare your genetic profile to users in the GEDmatch database. Emails are provided so you can quickly contact them if you go a hit. This is a simple and great resource for telling if y'all are related to anyone in the GEDmatch database.
- One-to-One Autosomal Deoxyribonucleic acid Comparing: This helps yous narrow down the comparison with one specific relative fellow member. Utilize this to confirm how much DNA data you actually share with that person before you reach out.
- Admixture (heritage): This is a well-known DNA analysis for identifying your ethnic roots. Like Ancestry Dna and 23andMe, it shows the proportion of your Deoxyribonucleic acid coming from a particular ethnicity/geography. Information technology's interesting to compare these results with that of other ancestry Dna testing kits.
All the same, there are numerous other tools listed on the GEDmatch homepage that you can use for different purposes (every bit pictured below). For first-timers, we recommend starting out with the iii tools listed above (boxed in red in the paradigm beneath). However, once you get accustomed to the free tools, consider upgrading to the Tier one package to become some really incredible tools.
GEDCOM Files
Yous may have noticed that GEDmatch likewise allows you to upload GEDCOM files, which store data about family copse. Using a GEDCOM file from Ancestry, MyHeritage, or whatsoever other family unit tree software, you tin compare your GEDCOM file to all files within the database, allowing you to see exactly how your family tree ties into other people's family trees. Yous may even exist able to see where you shared a mutual antecedent!
Tier 1 Tools
Though we won't get into how to utilize the advanced GEDmatch DNA tools here, it is worth noting: they are pretty absurd. Hither is a short description of some of the coolest tools GEDmatch users get access to:
Lazarus : Essentially, you tin can recreate a expressionless person'south genetic code using samples from their close relatives. While information technology won't bring them back to life - it is very helpful for using DNA data from an autosomal Dna test to exercise deep genetic genealogy research.
Phasing : This tool sorts out your chromosomes by using information from your mother and/or father. This allows you to run across exactly which parent gave you that crooked olfactory organ!
My Evil Twin : Your parents could have created many versions of yous, based on which genes they passed on. This simulation essentially recombines your genetics to estimate what traits your "evil twin" would accept carried.
In that location are many other traits available in Tier 1, allowing yous to explore specific segments of your DNA and many other statistical analyses!
How To Understand The Results
Once your results are ready, you are able to explore a number of features on GEDmatch. Here are the ii master tools:
How to Find My Deoxyribonucleic acid Relatives?
1. Ane-To-Many Deoxyribonucleic acid Comparison Result
When y'all click "One-To-Many Dna Comparing Result", you lot can see a list of contacts like below.
How practise you evaluate the results to decide who is a potential relative? Cheque "Overlap and Total cM" showtime.
"Total cM" is the total length of all substantial Deoxyribonucleic acid segments you share with a DNA match. "Overlap" is the full number of overlapping SNPs that you share with your lucifer. SNPs are "single nucleotide polymorphisms." You tin retrieve of them simply equally Deoxyribonucleic acid letters important in determining your unique genetic contour. Therefore, the larger the number of centimorgans you share with another user, the more than closely you are related.
The table* below summarizes the total cM expected from different degrees of relations within the family unit. For case, if your parents' data is on GEDmatch, they should show up as a match with over 3000 cM shared. If yous do it with keen-grandparents, information technology would be effectually 464-1486cM. Or 46-515cm with a second cousin.
Yet, GEDmatch also gives you the ability to change and modify this search. Y'all tin can acquire more about how your "match thresholds" can modify your results on the ISOGG Wiki.
*If you want farther details, DNApainter's comprehensive chart of cM estimator does a good chore of explaining this. Annotation that Deoxyribonucleic acid data files and their coverage of the genome differ across companies, so results may inevitably non be 100% accurate.
In conclusion, by checking "Overlap" and "Total cM", y'all may notice people who share a meaning amount of Deoxyribonucleic acid with y'all — people who potentially are your newfound relatives!
2. I-To-1 Autosomal Deoxyribonucleic acid Comparison
Once y'all find someone who shares a good clamper of Deoxyribonucleic acid information with you, you can commencement earthworks into the details of your DNA human relationship with them. The image below is from the 1-To-One DNA Comparison Result: it gives yous a visual representation of which segments of your DNA yous share with that person (chromosome browser). What yous want to see is how many blue chunks practice you have.
This ane-on-one matching can really help you lot narrow down who yous are related to and how much DNA you share with that person. You can too first to rail which segments of Dna you share with unlike people - little puzzle pieces in the story of how you came to be.
A Review of What Else Can Nosotros Practise With GEDmatch?
One-To-Many DNA Comparison Result and One-To-One Deoxyribonucleic acid Comparison Event are awesome tools to start with. Besides those, here'south our recommendation for what else to try.
Effort out Admixture / Oracle with Population Search.
This helps you learn what genetic ethnicity you have based on publicly available genealogy databases such as MDLP, Eurogenes, Dodecad, etc.
Here is a summary of the recommended databases to use based on your ethnicity:
MDLP — European, American
Eurogenes — European, American
Dodecad — Eurasians, Asians, Africans
HarappaWorld — S Asian
Ethiohelix — African
puntDNAL — (Unknown)
GedrosiaDNA — Eurasian (Indian and Asian)
Are Your Parents Related?

You lot would exist surprised - it is more common than people think, though the relationship is commonly very distant. This tool essentially compares each "phase" (maternal or paternal portion) of your Deoxyribonucleic acid to see if they are related to each other.
X-DNA Comparing
Using FamilyTreeDNA 10-DNA data, yous tin can compare your Ten-DNA directly to other users that accept uploaded their data.
One to One X-DNA Comparison is a unique feature that enables yous to do the same comparison as "One-To-I DNA Comparison", specifically for your 10 Chromosome. The master One to Ane comparing tool analyzes autosomal Deoxyribonucleic acid, which is your numbered chromosomes commonly used by ancestry Deoxyribonucleic acid companies. Y-Dna can trace your paternal line (father'southward side), X-Deoxyribonucleic acid does the same for your mother'south side maternal line.
The One to Many X-Dna comparison allows you to compare to all the users in the database at in one case and see if you share the same haplogroup and what percentage of the 10-Deoxyribonucleic acid you share. For males, 10-Dna is very telling of their maternal DNA ancestry (like to mtDNA).
You can acquire more nigh how to use this tool on this post as well!
