Simulated G25 coordinates

Everything G25 modelling needs, in one workbench

G25 coordinates for your DNA

Run a G25-ready calculator such as Eurogenes K15 on your raw DNA and Genoplot saves simulated Global 25 coordinates as a new sample, at no extra cost. Already have coordinates? Paste them in.

nMonte modelling

Pick ancient or modern source populations and nMonte finds the mix that fits your sample best, with a fit distance on every result. Not sure where to start? Quick Start picks the sources for you.

500+ community calculators

Ready-made G25 models published by Genoplot members, from hunter-gatherer and farmer splits to regional Bronze and Iron Age calculators. Run one on your sample in a click.

Charts, maps and sharing

Read each result as a chart or on a map, keep every run in History, and share it with a link.

From raw file to ancestry model in three steps

  1. 1

    Upload your DNA

    Add the raw file from 23andMe, AncestryDNA, FamilyTreeDNA, MyHeritage, LivingDNA or WeGene, exactly as you downloaded it.

  2. 2

    Get your coordinates

    Run a G25-ready calculator once for simulated G25 coordinates, or paste coordinates you already have.

  3. 3

    Run a model

    Choose a community calculator or your own source populations, and let nMonte find your mix.

Frequently asked

What is G25?

Global 25 (G25) describes a genome as 25 principal-component coordinates. Because every sample sits in the same space, yours can be modelled as a mix of reference populations, which is what nMonte does.

How do I get G25 coordinates for my DNA?

Upload your raw DNA file and run one of the calculators marked G25, such as Eurogenes K15. Genoplot saves simulated G25 coordinates as a new sample at no extra cost. Subscribers can also order Geno25 coordinates computed directly from the raw file.

Can I use coordinates I already have?

Yes. Paste them into the Quick Samples box on the nMonte workbench, one sample per line: a name followed by its 25 values.

Is it free?

Creating an account is free and needs no credit card. Free accounts get Compute Credits every month, and each calculator or nMonte run spends some of them. The Basic and Pro plans add more credits and more samples per run.

What does the distance mean?

It measures how far your sample sits from the model nMonte built for it. Lower is better, and comparing distances is how you choose between two models.
