DNA tests that give you a raw data file
This site reads the file, it does not test anyone. If you have not tested yet, these are the companies whose download it already knows how to read, and what we have learned from their files.
None of these links earns us anything, and no company paid to be listed. Disclosures
AncestryDNA
Visit AncestryDNAThe file: Tab-separated, the two alleles in separate columns, no-calls written as 0.
What we found: Numbers the sex chromosomes and mitochondria 23 to 26 instead of X, Y and MT. This site translates them; some older tools do not.
23andMe
Visit 23andMeThe file: Tab-separated, both alleles in one column, no-calls written as --.
MyHeritage DNA
Visit MyHeritage DNAThe file: Comma-separated with quoted fields.
FamilyTreeDNA
Visit FamilyTreeDNAThe file: Comma-separated with quoted fields; take the Build 37 autosomal file.
Living DNA
Visit Living DNAThe file: Text export from the account settings.
TellMeGen
Visit TellMeGenThe file: A bare four-column table with no vendor name in the header.
What we found: Omits rs429358, one of the two positions that define APOE, so APOE cannot be read from a TellMeGen file. The report says so rather than guessing.
Already tested?
Then you already own the file. How to download it from each company, then open the reader. Nothing is uploaded: the file is read by your own browser and forgotten when you close the tab.
Questions
Which DNA tests can Sequencings read?
Raw data files from AncestryDNA, 23andMe, MyHeritage DNA, FamilyTreeDNA, Living DNA, TellMeGen. All of them are genotyping chips that read roughly 650,000 chosen positions, and the file is read in your browser without being uploaded.
Does it matter which test I buy for this site?
Less than the marketing suggests. The 108 markers in the panel were chosen to be common variants, which are exactly what genotyping chips are built to read. Where we know a vendor leaves one out, it is listed on this page: a TellMeGen file, for example, cannot answer the APOE question.
Do I need whole-genome sequencing?
Not for this site. A chip reads about 0.02% of the genome's 3.1 billion positions; 30x whole-genome sequencing reads nearly all of them (accuracy 99.98 per cent at 30x). That matters for rare variants, which this site deliberately does not report. The reader does not yet accept whole-genome VCF files.
Can I use a file from a test I took years ago?
Yes. Download it again from the vendor's account settings. The file does not change after you test, and older chip versions still carry nearly all of the common positions in the panel.
