How to Download Your Raw DNA Data | 23andMe, Ancestry & More
Step-by-step guide to download raw DNA data from 23andMe, AncestryDNA, MyHeritage, FamilyTreeDNA, Nebula and Genera, then upload it for 20 free reports.
Which file should I upload from my provider?
From 23andMe and AncestryDNA, upload the .txt file inside the zip. From MyHeritage, upload the .csv inside the zip. From FamilyTreeDNA, upload the Build 37 Concatenated Raw data (.csv.gz). From Nebula Genomics, upload the VCF (.vcf or .vcf.gz). From Genera, upload the CSV. Maximum size is 50 MB.
Do I need to unzip the file first?
If your provider gives you a .zip, yes. GeneHealth accepts .txt, .csv, .tsv, .vcf and .gz files, but not .zip. A .gz file can be uploaded as it is, with no need to extract it.
Is it safe to download my raw DNA data?
Raw data is the same sensitive genetic information your provider holds. Providers point out that once the file is on your computer it is no longer covered by their security, so download it on a device you trust, do not send it by email and delete extra copies when you are done. On GeneHealth it is encrypted at rest and you can delete it at any time.
I can't find the download option. What now?
Interfaces change, and options can differ by country or kit version. Look for 'Download raw data' in your account settings or next to your DNA results. Some providers ask for your password, two-factor authentication or an email confirmation. GeneHealth needs the genotype file or VCF, not BAM, CRAM or FASTQ files. If you still cannot find it, ask your provider's support team.
What if my provider is not on the list?
GeneHealth officially supports 23andMe, AncestryDNA, MyHeritage, FamilyTreeDNA, Nebula Genomics and Genera. Files from other companies may still work if they use a standard raw data layout with rsID, chromosome, position and genotype columns, but we cannot promise it.
