If you already hold a Global25 row, you can get an admixture report for it free at Ancestrify. Not a trial, not a teaser locked behind a checkout: a solved composition per era, the three closest reference populations of every era, and the three closest notable individuals in each of three tiers, opened the moment you submit. The service is called G25 Admix, and the price is one contribution: your scaled row goes into a public, downloadable modern Global25 dataset under the country you choose, with nothing else attached.
One honest line before the rest. The report is free; the coordinates are not. Official Global25 coordinates come from one place, Davidski's independent Eurogenes G25 Requests portal, and their site states 15 EUR per kit. If you do not have a row yet, skip to that section. If you do, here is exactly what you get and what you give.
What the free G25 Admix report contains#
Everything sits in one view, with the same reveal and toolbar as the paid reports:
- Your admixture per era. Your row is solved with the calculator built for your country and the region your origin pin falls in, not a generic worldwide panel. Each source population is drawn in the Lamplight portrait set, and shares under 1.5 percent fold into a single "Other" row so the picture stays readable.
- The three closest populations of every era. Six distance eras, from the Late Bronze Age to the modern day, each with its three nearest reference populations by Euclidean distance in Global25 space. Tap any population to open the individual samples behind its average.
- The three closest notable matches per tier. Historical figures (people history knows by name, with published ancient DNA), iconic discoveries (mummies, warriors and burials that made headlines) and deep time individuals from the Ice Age. Tap a portrait for the dossier.
- A stat strip naming your leading source, your closest population and your closest notable, so the headline is legible before you scroll.
The paid Global25 analysis opens every chapter behind these: the full ranking of every era, the admixture atlas, PCA, the whole notable catalog, the reading and the ancestry videos. The free report is the first three rows of each of those tables, solved properly, with the artwork, from the row you already have.
What you give in exchange#
Public modern Global25 references are thin. Population averages are published; the individual rows behind them almost never are, and the rows that circulate on forums carry no label anyone can check. The modern G25 dataset fixes that one person at a time, and your contribution is one row in it.
What is published: your scaled coordinates exactly as Davidski sent them, 25 values, and one country label. That is the whole record. A line in the file looks like this (the modern German population mean, shown for the format only, not a real person's row):
German,0.130299,0.137378,0.057363,0.037865,0.039566,0.015146,0.004177,0.005897,0.003746,0.001633,-0.004331,0.002316,-0.005334,-0.001744,0.008738,0.002822,-0.0033,0.001633,0.003531,0.001114,0.002947,0.001801,0.000337,0.00836,0.000074
What stays private: your name (it only addresses the report), the pin you drop on the map, the region it resolves to, your raw coordinates (kept only to catch duplicate submissions) and any note you leave. None of it enters the public file.
The file is plain text in the format every Global25 tool already reads, free to download and free to use, with attribution to Ancestrify appreciated. Ancestrify uses it to improve its own modern references and to publish statistics over time. Your Global25 coordinates are a description of your genome, so contribute only if you are comfortable with that description being public under your country.
How to get it, step by step#
The whole submission takes about a minute.
- Create a free account and verify your email. No purchase is needed at any point. One verified account can contribute one person's row, which is how the dataset stays one person, one row.
- Open the G25 Admix page from your dashboard at /dashboard/g25-admix.
- Paste your scaled row. One line, the label optional, then the 25 scaled values exactly as Davidski sent them. If you prefer, upload the unmodified .txt file he sent, Scaled block and Raw block intact. The row is checked against the original Global25 grid as you type.
- Give your full name and choose your country. The name addresses your report. The country is the label your row is published under and the calculator that solves your composition.
- Drop a pin where your family comes from. The pin must sit inside the country you chose. It assigns your region within that country, and it is never published.
- Publish. Your row joins the dataset at once and your report opens in the same moment.
If no calculator covers your country at the instant you submit, the row still publishes, the report completes within the hour and you are notified. Every sovereign state is in the catalog, and the calculator program keeps closing gaps.
Why the row is checked against the original grid#
The dataset is only worth downloading if every row in it is an unmodified official projection, so the form refuses anything that is not. Original scaled Global25 exports print on a numeric grid. A row converted from calculator percentages, produced by a "G25 simulator", or edited by hand falls off that grid in ways that are easy to detect: many components off the lattice at once, long floating point tails where the real service rounds, marker words in the sample name. The same forensic check is available free and standalone at the G25 Authenticity Check, and it runs locally in your browser.
This is also why a simulated row would not be doing you any favours in the report itself. A fabricated row is pulled toward whichever averages fabricated it, so distances and admixture come back tidier than your genome supports. If you are unsure whether the row you hold is the scaled or the unscaled one, this guide tells them apart.
The other rule is one person, one row. A vector already in the file is refused whoever sends it, so nobody appears twice under two labels. If you want to contribute for a relative, they open their own free account and do it themselves in a minute.
If you do not have your coordinates yet#
Two routes, both open to anyone.
Route one: order them yourself. Go to Davidski's independent Eurogenes G25 Requests portal, upload the raw DNA file from 23andMe, AncestryDNA, MyHeritage, FamilyTreeDNA or LivingDNA, pay their fee (their site states 15 EUR per kit) and wait for the row (their site states 2 to 7 days). What that portal is and what comes back is written up separately. When the file arrives, come back and paste the scaled row.
Route two: have them obtained for you. Order the Global25 analysis with your raw file instead of a row and add the Coordinate Concierge (+15 EUR, a pass-through of the portal's fee). Ancestrify places the request with that same service on your behalf, your full analysis runs the moment the row arrives, and the row is yours to keep. Both routes are laid out side by side at /get-g25-coordinates.
No testing company produces Global25 coordinates, and Ancestrify never computes them. Anything that claims to produce your row without the reference dataset is a simulation, and simulated rows fail the grid check above.
Free report versus the Global25 analysis#
| G25 Admix (free) | Global25 analysis (29.99 EUR) | |
|---|---|---|
| Composition per era | Yes, with the country and region calculator | Yes, on the map, era by era, with the Calculator Explorer |
| Closest populations | Three per era | Every population ranked, in every era, drawn on the map |
| Notable matches | Three per tier | The whole catalog ranked and mapped |
| PCA | No | Yes, where you fall among the ancient samples |
| The reading | No | A written chapter on what the results mean |
| Ancestry videos | No | Yes, rendered from your rankings |
| Personalized Calculator | No | Optional add-on, a panel built around your row |
| Input | Your official scaled row | The same row, already in place |
The paid report starts from the coordinates you already gave, so nothing is re-entered. If the free view answers your question, you are done and you paid nothing. If it raises the next one, the full G25 analysis is one payment and the same row.
Privacy, removal and the licence#
The published record is a country label and 25 numbers. No name, sample id, email, place or note is ever in the file. If you later want your row out, write to support and it is removed the same day, with the public file rebuilt without it; copies other people already downloaded are outside anyone's control, which is worth knowing before you contribute. Deleting your account removes every row you contributed, published or not.
Contributors grant the licence described in the terms of service: perpetual, worldwide, royalty free, for the dataset to be downloaded and used for research, tools and statistics. The privacy notice names contributed coordinates as their own data category.
Frequently asked questions#
Is the G25 Admix report really free?#
Yes. It costs no money at any step. The exchange is your scaled Global25 row, published under your country in the public dataset. You need a free account with a verified email and nothing else. The coordinates themselves are the one thing in the Global25 world that is not free; they come from Davidski's portal, which states 15 EUR per kit.
Do I need to buy anything from Ancestrify to get it?#
No. The free report is not a trial and does not expire. The paid Global25 analysis is offered at the end of the report for anyone who wants every ranking, the atlas, PCA, the reading and the videos, and it reuses the same row, but the free view stands on its own.
What is published about me?#
One line: a country label and 25 scaled values. Your name, your origin pin, your region, your raw coordinates and any note stay private. The row cannot be traced back to you from the file, but Global25 coordinates describe your genome, so treat the decision as publishing that description.
What if my country has no calculator yet?#
Your row still publishes at once and the report completes within the hour, after which you are notified. The catalog covers every sovereign state and the calculator program keeps closing the remaining gaps. If your country is not in the list at all, write to support with the label you would use.
How is the free report different from the paid G25 analysis?#
The free report shows your composition per era, three closest populations per era and three closest notables per tier, in one view. The paid analysis (29.99 EUR, one time) opens the full ranking of every era on a map, the admixture atlas with the Calculator Explorer, PCA, the whole notable catalog, a written reading and the ancestry videos, and starts from the row you already contributed.
