How to Upload Raw Dna to Gedmatch
By Dr. Brandon Colby MD, a doctor-practiced in the fields of Genomics and Personalized Preventive Medicine.
If yous're looking for one of the most popular gratis Deoxyribonucleic acid upload sites, GEDmatch is information technology.
GEDmatch, founded past Curtis Rogers and John Olson in 2010, is a website where people can upload their DNA data from several different Deoxyribonucleic acid testing companies. After uploading data to GEDmatch's Deoxyribonucleic acid database, a user tin can so interact with other GEDmatch users and employ GEDmatch'due south genetic genealogy features.
GEDmatch does non offer its ain DNA testing services but does allow you to upload your Dna examination data from testing offered by whatever of the following exam providers:
- 23andMe
- MyHeritage
- LivingDNA
- Family Tree Deoxyribonucleic acid (FTDNA)
- AncestryDNA
- Sequencing.com
Near the DNA Site GEDMatch
GEDmatch is a costless genetic genealogy site that allows users to upload their autosomal Deoxyribonucleic acid exam results to the site'due south Dna database. Users can and then use the site's tools to identify Dna matches and learn more about family history through the GEDmatch DNA database. The site analyzes 10 chromosome and autosomal genetic information to deliver its results, which has proven to exist highly constructive.
GEDmatch is known for its apply past law enforcement, just many people utilise it for personal Dna research. Police enforcement searches are what makes GEDMatch'southward privacy worrisome for many people, every bit the DNA information uploaded to the site has been used in constabulary enforcement investigations.
The privacy concerns came to light in May of 2018 when the DNA database was used by law to identify the suspect in the Aureate State Killer case in California. GEDmatch tried to act fast in regaining the confidence of users by irresolute their site policy and terms of service. They even added a privacy pick for users to opt-in or opt-out of law being able to access their Deoxyribonucleic acid databases.
The opt-in or opt-out pick may accept helped them regain conviction from users, but information technology was short-lived. A few months later in November 2019, a law enforcement officer obtained a warrant to access ALL of the GEDmatch DNA data. This includes people who opted out of having their data searchable by police force enforcement investigators.
A calendar month afterward in Dec, Verogen purchased GEDmatch. Verogen is a forensic testing visitor that works with constabulary enforcement agencies.
Despite the focus on police force enforcement use, GEDmatch.com continues to be a pop genealogical tool used by genetic genealogists. The reality is the genealogy website offers a wealth of information that tin assist family members find each other through the family finder tool, mutual ancestors with DNA ancestry tools, and acquire more about ethnicity and family unit history for building family trees.
The GEDmatch admixture/heritage tool allows users to pick the project they desire to compare their DNA to and each project produces unlike results.
When because all of the Deoxyribonucleic acid information GEDmatch has available, many people do not find the privacy concerns a deterrent. Afterward all, the merely people who should really be concerned about privacy are those involved in cold cases.
Uploading Dna Data to GEDMatch
Yous tin can upload your Dna file to the genealogy database within a few minutes. All y'all have to do is go to the registration page to register.
After registering, yous can upload your DNA data file from the SNP-based testing visitor you lot used for testing. Yous can download your data from your DNA testing company by following the below links to tutorials on how to download raw DNA information.
- 23andMe
- MyHeritage
- LivingDNA
- FamilyTreeDNA (FTDNA)
Depending on which DNA testing company you used, you will either have a file or folder. GEDmatch will only accept "23andMe format" This is the almost popular personal genomic information format.
What GEDmatch Will Non Accept
In addition to VCF, GEDmatch will non accept total exomes or genomes. It too does not recommend uploading imputed DNA data.
GEDmatch does not accept DNA data in any of the following formats:
- FASTA
- FASTQ
- BAM
- CRAM
- genome VCF (Variant Call Format)
- standard VCF
If you have Deoxyribonucleic acid data in one of the formats above, you tin utilise the Ultimate Compatibility app at Sequencing.com to catechumen your file into an Ultimate Compatibility File, which is compatible with GEDmatch and most other third-political party sites that allow Dna data uploads.
To automatically convert your DNA data file to an Ultimate Compatibility File, first by uploading your Deoxyribonucleic acid data and then using the Ultimate Compatibility app.

How to Convert a VCF to 23andMe Format
If you desire to convert your VCF to 23andMe's format, start by downloading the codebase from this GitHub repo: VCF-to-23andMe
Run the data_to_db.py script using your VCF equally input. This will generate a genome.db file (>python3 data_to_db.py input.vcf.gz vcf genome.db).
Then you run the db_to_23.py script using the genome.db file every bit input. This is what produces the 23andMe format (>python3 db_to_23.py genome.db blank_v3.txt 23andMe.txt).
Open the text file to make sure it is in the right format. Information technology should have # rsid chromosome position genotype at the top of the document.
The file is ready for uploading if information technology contains the above.
Setting Up a GEDmatch Genetic Profile
When uploading raw DNA data to the genetic database, users must answer questions to consummate their profile. These questions help build the kit on the site. This is when users can opt-in or opt-out of granting law enforcement officials access to their raw DNA data for criminal searches.
Continue in mind, even if users opt-out of granting access, a court tin can grant GEDmatch data access to a law enforcement member. This usually happens when there is a common cold case, like in the example of the Aureate Land Killer and violent crimes.
In other words, while the information may non exist easily attainable, information technology'southward still is if needed for Dna matches to criminal offense scene Deoxyribonucleic acid collection.
It's also of import to know that even if you may not have been involved in a crime, you could lead police to distant relatives only because your Deoxyribonucleic acid matches what was nerveless at the crime scene.
DNA Kit Numbers: How Information technology Works
Every profile and kit has a number. The GEDmatch Kit Numbers are unique identifiers every uploaded Dna kit receives. It is non the same every bit the number the Dna testing company labels Dna results.
This kit number is what you volition use whenever using your DNA data with the GEDmatch site. It is fastened to each person's DNA contour.
GEDmatch is generally complimentary, but there are GEDmatch tier 1 tools that crave a subscription. This subscription costs $x per month. If you lot are interested in genetic genealogy, this cost may be worthwhile.
