The complete coordinate package.
Each purchase includes both genome-wide and chromosome-level outputs. Use the format required by your calculator, model, or research workflow.
Genome-wide scaled coordinates
Eigenvalue-weighted G25 coordinates used by many distance tools and compatible calculators.
Sample_scaled, val1, …, val25Genome-wide unscaled coordinates
The corresponding 25 principal component values without eigenvalue weighting, for workflows requiring the unscaled format.
Sample, val1, …, val25Chromosomes 1–22
Scaled and unscaled coordinate sets for each of the 22 autosomal chromosomes. Useful for chromosome-level comparison and exploration.
Chr 01–22 · both formatsFor coordinate-based analysis.
G25 coordinates are inputs to a model. The meaning of any comparison depends on the reference populations and distance method you choose.
Work with the numbers
- Measure genetic distance to selected reference datasets.
- Compare modern or ancient reference positions.
- Use G25 Studio or compatible independent workflows.
- Test how alternative reference panels affect results.
An interpreted ancestry report
- Ready-made ethnicity or nationality percentages.
- A definitive statement of identity or family history.
- A medical or health-related DNA interpretation.
- A result that is meaningful without reference data.

A defined projection workflow.
Compatible raw autosomal data is projected into the Global25-style reference space, then prepared as reusable coordinate files.
Provide raw DNA
Start with a sufficiently complete autosomal SNP export from a supported consumer DNA provider.
Project and calculate
The genotype is processed against the chosen reference framework to produce 25-dimensional position values.
Download your files
Receive the genome-wide and chromosomal outputs in scaled and unscaled formats through your account.
Compatible file sources
Compatibility depends on marker coverage and file completeness, not only the provider name. Provider names describe file-source compatibility, not endorsement or affiliation.
Understand the limits of the model.
Reliable analysis means keeping the model, reference panel, scaling format, and interpretation separate.
Reference-dependent
Distances and modeled similarities vary with the populations included in the comparison panel.
Format-dependent
Use scaled coordinates with scaled references, and unscaled coordinates with unscaled references. They are not interchangeable.
Privacy-sensitive
Coordinates are derived genetic information. Store them securely and review third-party privacy terms before uploading them elsewhere.
This product supplies numerical position data, not a diagnosis, a demographic identity assignment, or proof of a specific historical ancestor.

Keep the flexibility.
A straightforward purchase for people who know they want G25 position data and the freedom to analyze it with their own references.

Frequently asked questions.
What are G25 coordinates?
G25 coordinates are a 25-dimensional numerical representation derived from genome-wide variation. They support statistical distance calculations and comparison with modern or ancient reference populations.
Are G25 coordinates ethnicity percentages?
No. Coordinates describe a position in a model. Percentage estimates are produced later by comparing that position with selected references, and remain model-dependent estimates rather than proof of ancestry or identity.
What is the difference between scaled and unscaled coordinates?
Scaled coordinates weight dimensions by their eigenvalues and are used by most G25 tools. Unscaled coordinates retain the PCA output without that weighting and support specialized workflows.
What files do I receive?
The service provides genome-wide scaled and unscaled coordinates plus scaled and unscaled coordinates for autosomal chromosomes 1 through 22 in compatible text formats.
Can I use the files outside G25 Studio?
Yes. The coordinate formats can be used with compatible third-party G25 tools or independent scripts. Check each tool's expected format and methodology before sharing data.
Which raw DNA providers are supported?
The service accepts sufficiently complete autosomal raw-data files from supported providers such as 23andMe, AncestryDNA, MyHeritage, FamilyTreeDNA, and Living DNA.
Do coordinates change over time?
Your underlying DNA does not change, but a future reference-space or projection-method update could produce a revised coordinate set.
How should I protect coordinate files?
Coordinates are derived genetic data. Store them securely, share them only with services you trust, and review the receiving service's privacy terms before upload.
