Bring your Global25 coordinates, or let us get them
This analysis starts from a Global25 coordinate row. Already have yours? Paste it at checkout and the report is computed automatically, for €29.99. Don't have coordinates yet? Upload the raw DNA file you already have and, with your explicit consent, we obtain your official coordinates from Davidski's independent Eurogenes G25 Requests service for a €15 service fee, your analysis runs the moment they arrive. Either way, the coordinates themselves always come from that independent service; here is how getting them works, and our step-by-step guide covers the do-it-yourself route for every testing company.
This is our Global25 product, which is a different method from qpAdm, and qpAdm is the one that takes a raw DNA export. It merges your export against the Allen Ancient DNA Resource and returns a formally tested ancestry model with p-values and standard errors, which Global25 does not produce.

What a coordinate fit can and cannot tell you
Global25 places every sample as 25 numbers in a shared space, which makes it fast and enormously flexible: distances, mixture models and projections all become arithmetic on coordinates. That is why it is the workhorse of amateur population genetics.
It is worth being clear about its limit. A mixture solver returns the combination of sources that lands closest to your point, and some combination always lands closest , the method has no way to say that a model is incompatible with the data. That is what fit distance is for, and it is why we show it rather than presenting the percentages alone. If you want a result that can be statistically rejected, that is qpAdm.
How each of the three analyses works
Distance is a single operation repeated across a panel. For each reference population, the difference from your coordinate is taken in each of the 25 dimensions, squared, summed and square-rooted, plain Euclidean distance, and the list is sorted closest first. It is deterministic: the same row against the same era always produces the same ranking. Because a reference population is an average of individuals, and individuals scatter widely around their group's centre, a close distance is evidence about populations rather than about any person who lived.
Admixture asks a different question: which weighted mixture of source populations lands nearest your point? The search is a Monte-Carlo fit in the nMonte tradition, and the leftover gap between the mixture and your coordinate is reported as the fit distance. Each era's model is fitted against a curated source panel, and the report lists every population that panel offered, including the ones the model was offered and did not use. Those rejected sources appear nowhere else, and showing them is what stops a breakdown reading as the only possible answer. Where the ancient record has gaps, some reference populations are living peoples rather than excavated genomes; each such population says so in its details.
PCA projects the coordinate space down to a readable scatter and places you among individual samples, not population averages, which is the distinction that makes the plot informative, because it shows the spread real people occupy rather than a tidy row of group centroids. The axes are not ancestries, and closeness on a two-dimensional plot can hide separation in the dimensions the projection discarded.
Reading the report honestly
Three habits keep a coordinate report useful. First, read groupings rather than individual lines: sources that sit close together in the reference space trade weight almost freely, so the total two related sources share is far more stable than their split. Second, treat rank order as orientation, not significance, populations separated by a thousandth in distance are, for practical purposes, tied. Third, compare across eras rather than fixing on one: your position relative to a Bronze Age panel and a modern one are different measurements, and the movement between them is the interesting part.
The report also states its own scope on every era, the calculator used, your declared ethnicity, the regions included and the size of the source panel, because a percentage means nothing without the panel it was fitted against. Sources under 3% that the chart folds into “Other” appear in that provenance list with their real values.
A calculator built around you
Every published calculator is a compromise: a source panel chosen to work for a whole region. The Personalized Calculator is the opposite, an analyst hand-builds a Global25 calculator around your own coordinates, choosing and stress-testing the source populations that actually explain your row, and publishes the result as a second version beside your standard admixture result. Both stay. You switch between them from the report, and each states the panel it was fitted against.
It is a €10 one-time add-on, the same price at checkout or later on the report, and because it is human work it arrives after your standard result publishes; you are notified the moment it is ready. The catalog it draws on covers every sovereign state, 199 countries and 1,115 regions, for Global25 as well as qpAdm.
Free coordinate tools, no account needed
Most of the tooling is public and free. The G25 distance calculator ranks your closest populations across six eras, the admixture calculator models mixtures against curated or pasted panels, Average G25 builds a population average from individual rows, and the authenticity check flags simulated, edited or precision-lost coordinate rows. All four run in your browser, nothing is uploaded, and none of them needs an account.
If you are new to the method, How to read a Global25 report explains what the numbers mean, getting your G25 coordinates covers the two ways to obtain a row, do it yourself, or have us do it for you, and qpAdm vs Global25 sets out when a coordinate fit is the wrong instrument. Terms are defined in the glossary.
Questions
What is the Personalized Calculator?
A Global25 calculator an analyst builds by hand around your own coordinates, rather than one chosen from the published library. It is published as a second version of your admixture result beside the standard one; both stay, and you switch between them from the report. It is a €10 one-time add-on, at checkout or later on the report, and it arrives after your standard result publishes because it is human work, you are notified the moment it is ready.
Which countries does the catalog cover?
Every sovereign state, 199 countries and 1,115 regions, for Global25 as well as qpAdm, so a declared ethnicity anywhere in the world scopes the analysis to a real region rather than a continent.
Do you generate Global25 coordinates from my raw DNA?
We never compute coordinates ourselves, official Global25 coordinates always come from the independent Eurogenes Global25 service. If you already have your row, paste it at checkout and the analysis runs on your exact coordinates. If you don't, choose the upload option instead: with your explicit consent we pass your raw DNA file to that provider, obtain your official coordinates for you for a €15 service fee, and run your full analysis the moment they arrive.
How transparent is the analysis?
Completely, and on purpose. Every era publishes the full source panel the model was offered, split into the populations it used and the ones it rejected; it states the calculator, your declared ethnicity, the regions and the size of the panel; and every fit is reported with its fit distance. Every curated calculator we use has a public page listing its whole panel, and the Personalized Calculator says exactly which sources it was built from. Nothing is hidden behind a score, so anyone with the same coordinates and panel can reproduce the result.
Can I see which populations the model could have used?
Yes. Each admixture era lists every population in the calculator it was fitted against, split into two labelled groups: the ones the model used, and the ones it was offered and did not use. The rejected populations appear nowhere else in the product, and showing them is what stops a breakdown looking like the only possible answer. The report also states the scope — the era, your declared ethnicity, the regions, and the size of the source panel — and a source below 3% that the chart folds into Other appears there with its own real percentage.
What do I get for my coordinates?
Three analyses across six eras: distances to the closest reference populations, an admixture model of your coordinate as a mixture of source populations, and a principal-component scatter placing you among individual samples. Each comes with a downloadable cinematic video, plus the free Notable Matches lens, which ranks your coordinate against a curated catalog of famous ancient individuals.
Can I compare my DNA to famous ancient people?
Yes, every report includes Notable Matches, free: your coordinate ranked against 254 curated notable individuals with published ancient DNA, from named historical figures to iconic discoveries and Ice Age individuals, each with a portrait, dossier and map. A small distance means your genome sits near that person's in the reference space, similar ancestry composition, never proof of descent, and we never claim a notable individual is your ancestor or relative. The full catalog is browsable publicly on the Notable Matches directory.
How large is the reference set?
30,386 individual samples and 1,535 curated populations. Distances are computed across six eras, Late Bronze Age, Pre-Classical Iron Age, Imperial Antiquity, Middle Ages, Early Modern and Modern Era, and the 25 closest populations are returned for each.
Does the PCA plot populations or individuals?
Individuals. The scatter places you among individual ancient and modern samples rather than among population averages, across 12 regional groupings, so you can see how much internal spread a population actually has instead of a single point standing in for thousands of people.
How are the distances calculated?
Euclidean distance across all 25 dimensions of the Global25 coordinate space, against every reference population in the selected era, ranked closest first.
How is admixture modelled?
With a Monte-Carlo solver in the nMonte tradition: your coordinate is fitted as a weighted mixture of curated source populations, small components are pruned, and the model is re-solved. Every result is reported with its fit distance so you can see how well the mixture actually reproduces your coordinate.
Are these percentages the same thing as qpAdm proportions?
No, and the difference is worth understanding. A Global25 admixture percentage is a coordinate-fitting estimate: the solver returns the mixture that lands closest to your point, and some mixture always exists. qpAdm works from allele-frequency statistics and reports a p-value, so it can reject a model as incompatible with the data. Global25 is faster and broader; qpAdm is the one that carries statistical confidence.
How long does it take?
With pasted coordinates, results are computed automatically, there is a holding period by default, which the optional fast-compute add-on removes so your report is built as soon as you have paid. If we are obtaining your coordinates for you, the independent provider's manual step comes first and your analysis runs the moment your coordinates arrive. We email you as soon as your report is ready.
