What G25 Coordinates Are

G25 coordinates are a compact numeric representation of your genetic position in multi-dimensional space, designed for population comparison and modeling.

Numerical Representation

A sequence of 25 numerical values that encode genetic variation patterns derived from genome-wide analysis.

Global25 Framework

Based on the Global25 population genetics model, a standardized coordinate system used in genetic ancestry research.

Multi-Dimensional Space

Each coordinate represents a dimension of genetic variation, allowing precise positioning relative to reference populations.

Coordinate Format Example
SampleName_scaled,0.0234,-0.0156,0.0089,-0.0312,0.0178,...

25 numerical values representing your position in genetic space

What G25 Coordinates Are Not

Clear boundaries prevent misinterpretation.

Not Ethnicity Percentages

Coordinates are positional data, not percentage breakdowns. They describe where you are, not what proportion of something you are.

Not Identity Labels

No ethnic, cultural, or national labels are assigned. Coordinates are mathematical, not categorical.

Not a Report

You receive raw positional data. Interpretation requires additional tools and context.

Not Meaningful Alone

Coordinates require comparison with reference populations and analysis tools to derive insights.

"Coordinates describe position — not meaning."

Why Coordinates Matter

The infrastructure layer for ancestry analysis.

01

Enable Distance Calculations

Measure genetic distance between yourself and any reference population. Distance values quantify similarity and difference with mathematical precision.

02

Allow Population Comparison

Compare your position against thousands of ancient and modern reference populations. Identify which populations cluster nearest to your coordinates.

03

Support Ancestry Modeling

Use optimization algorithms to model your ancestry as combinations of reference populations. Test hypotheses about ancestral composition.

04

Power Analysis Tools

G25 coordinates are the input format for G25 Studio and compatible third-party analysis platforms. Your coordinates unlock an ecosystem of tools.

What You Receive

Clear deliverables, standardized formats.

Scaled Coordinates

Eigenvalue-weighted coordinates optimized for most ancestry modeling applications. The standard format for G25 analysis tools.

Format: SampleName_scaled,val1,val2,...,val25

Unscaled Coordinates

Raw PCA output without eigenvalue weighting. Useful for specialized analyses where lower-variance dimensions carry significance.

Format: SampleName,val1,val2,...,val25

Chromosomal Coordinates

Per-chromosome coordinate sets for advanced users investigating chromosome-specific ancestry patterns and recombination.

Includes: Chromosomes 1-22
Compatible with G25 Studio, third-party G25 tools, and independent analysis workflows.

How G25 Coordinates Are Generated

A principled methodology.

1

Genome-Wide Data Extraction

Your raw DNA data is processed to extract autosomal SNP markers used in population genetics analysis.

2

Reference Population Projection

Your genetic data is projected onto the Global25 reference space, defined by principal component analysis of diverse world populations.

3

Coordinate Calculation

Your position in 25-dimensional genetic space is calculated and output as numerical coordinates.

4

Scaling and Validation

Both scaled and unscaled versions are generated and validated for consistency with established population genetics methods.

Data Source Compatibility

We accept raw DNA files from major testing providers:

23andMe AncestryDNA MyHeritage FamilyTreeDNA LivingDNA

Who This Service Is For

Setting appropriate expectations.

Advanced Ancestry Users

Individuals familiar with genetic genealogy concepts who want to move beyond simplified ethnicity estimates to precise positional data.

Researchers & Analysts

Population genetics enthusiasts and researchers who work with coordinate-based analysis methods and distance calculations.

G25 Studio Users

Users planning to analyze their ancestry using G25 Studio or compatible third-party tools that require G25 coordinate input.

Looking for a ready-to-read report? If you want narrative interpretation rather than raw data, consider our Explorer Pack or Starter Pack instead.

Responsible Use and Interpretation

Powerful data requires careful handling.

Coordinates Require Tools

Raw coordinates are not self-interpreting. Use G25 Studio or similar platforms to calculate distances and model ancestry.

Distances Are Relative

Genetic distances are comparative measures, not absolute statements. Context and reference populations determine meaning.

Models Are Approximations

Ancestry models are statistical fits, not historical records. Multiple models may fit equally well.

Contextualize with Populations

Always interpret coordinates in relation to reference populations. Isolated coordinates convey no ancestry information.

Misinterpretation leads to false conclusions. Treat coordinates as data infrastructure, not as identity.

Coordinates, Studio, and Reports

Understanding the ecosystem.

User Interpretation

You Analyze the Output
  • G25 Studio provides analysis tools, not a narrative report
  • You evaluate distances, models, and plots in context
  • Compare alternatives and test hypotheses responsibly
  • Best for: Users who want control and are willing to interpret
Outputs: Distance tables, model fits, PCA/MDS plots

Coordinates give you your position. Studio turns position into analysis.

Next Step: Analyze in G25 Studio

Once you have your G25 coordinates, use G25 Studio to measure distances, test models, and compare populations with full transparency.

Frequently Asked Questions

What are G25 coordinates?

G25 coordinates are a 25-dimensional numerical representation of your genetic position, based on principal component analysis of genome-wide data. They allow you to compare your genetic profile with reference populations using distance calculations.

Are G25 coordinates the same as ethnicity percentages?

No. Coordinates describe your position in genetic space, not percentages of ethnicities. Ancestry percentages are derived from modeling coordinates against reference populations—they are an interpretation layer, not the coordinates themselves.

What is the difference between scaled and unscaled coordinates?

Scaled coordinates are weighted by eigenvalues, emphasizing dimensions that capture more genetic variance. Unscaled coordinates retain the original PCA output. Most analysis tools use scaled coordinates, but unscaled versions are useful for specific research applications.

Can I interpret coordinates without G25 Studio?

Yes, if you have the tools and knowledge. Coordinates are a standardized format compatible with various third-party applications and custom scripts. However, G25 Studio provides the most accessible interface for distance calculations and ancestry modeling.

Do coordinates change over time?

Your genetic data does not change. However, reference datasets and projection methods may be updated. If significant methodology changes occur, we may offer coordinate recalculation.

What DNA file formats are supported?

We accept raw DNA files from 23andMe, AncestryDNA, MyHeritage, FamilyTreeDNA, and LivingDNA. Files must contain sufficient autosomal SNP data for accurate coordinate generation.

Is my data secure?

Yes. We use enterprise-grade encryption and do not share your genetic data with third parties. Your coordinates are generated securely and stored privately in your account.

What can I do with my G25 coordinates?

Use them in G25 Studio to run ancestry calculators, calculate population distances, visualize your genetic position on PCA plots, and model your ancestry as combinations of reference populations.

"Every analysis begins with a position."
