My SelfDecode DNA file doesn't work with another service
For compatibility, SelfDecode provides raw DNA files in the same simple format [.txt] used by 23andMe, which means they should work with most third-party services that accept 23andMe data. That said, every platform has its own technical requirements, and we can’t guarantee compatibility with all services. Read below for some tips on getting your SelfDecode DNA file to work with other companies.
🛑 Before you spend money uploading your sensitive DNA data to another platform, we want you to know: SelfDecode offers one of the most comprehensive DNA testing platforms available — including our own version of reports offered by many other companies.
In many cases, the insights you’re looking for are already included in your SelfDecode membership. Instead of paying to upload your DNA elsewhere, we recommend emailing support@selfdecode.com first. We’ll gladly help you find the report or feature you need.
We’re here to make sure you’re getting the most value out of your DNA.
Why Another Company Might Not Accept Your SelfDecode File
In most cases, upload issues are caused by how the file header is formatted. Some platforms are very strict about what they expect to see at the top of the file and may reject it if the header doesn’t match their exact specifications.
What You Can Try
If you’re comfortable editing a text file, you can try one of the following fixes:
Option 1: Add a 23andMe Identifier
Add the following line as the very first line of the file:
# 23andme
Option 2: Simplify the Header
Remove all header lines except for this one:
# rsid chromosome position genotype
After making the change, save the file and try uploading it again.
💡 Tip: Always keep a backup copy of your original DNA file before making any edits.
If It Still Doesn’t Work
If the file is still being rejected, we recommend reaching out directly to the other company’s support team. They can tell you:
- Which DNA formats they accept
- Whether they have specific header or file structure requirements
Since each platform sets its own rules, their support team will be best equipped to help.
