Uploading your DNA file

IoA works with raw DNA files from the major consumer testing companies. You upload the file on the Home page; we handle the format conversion automatically.

Supported providers

• 23andMe. Download from Account, then 23andMe Data, then Your Raw Data. The file is a .txt.
• AncestryDNA. Request from Settings, then Privacy, then Download My Data. The file is a .txt.
• FTDNA (Family Tree DNA). Go to myDNA, then Download Raw Data. The file is a .csv.
• FTDNA Legacy. Use the legacy Raw Data download from your account page. The file is a .csv.
• MyHeritage. In the DNA section, open Manage DNA Kits, then Download. The file is a .csv.
• LivingDNA. Go to your profile and select Download Raw Data. The file is a .txt.

File size limit

Files must be under 50 MB. Raw DNA files from all supported providers are well under that limit, so this only applies if you're uploading a non-standard export.

The Processing state

After you upload a file it briefly shows as Processing. This is the conversion step where we normalize the format and index the SNP data against our reference panels. It usually takes a few seconds. Once it shows as Ready, you can run analyses.

Why upload can fail

Upload fails for a few common reasons.

• Wrong file. You uploaded a PDF report or a summary CSV instead of the raw data file. Download the raw data specifically.
• Wrong provider selected. You chose 23andMe in the selector but uploaded an AncestryDNA file, or vice versa. Select the provider that matches your file.
• Corrupted download. Re-download the file from your provider and try again.
• File too large. Only applies to non-standard files; standard exports from all supported providers are small enough.
