How do I get my G25 coordinates? Two ways, from 15 EUR

A Global25 (G25) coordinate row is a single line of 25 numbers computed from your raw DNA, a position in a shared genetic space alongside tens of thousands of ancient and modern samples. Once you have your row, an entire ecosystem opens up: distance calculators, admixture models, PCA plots. One thing about coordinates is not negotiable: only Davidski's independent Eurogenes G25 Requests service produces official coordinates. No testing company includes them, and any site claiming to compute them from your file is giving you a simulation. That includes us, we never compute coordinates ourselves, which is exactly why the two routes below both end at that one service.

Not sure what your raw-data export contains? The free file check reads your file in the browser and tells you, per product, whether it can be used, before you create an account or pay anything. A VCF from whole-genome sequencing, or a truncated download, is caught there rather than at checkout. Already holding a coordinate row of unknown origin? The free authenticity check reads its numeric fingerprint and flags simulated, converted or rounded rows.

Every way to end up holding a Global25 row, with the price each site states. Only the first two produce the official row.

• 01

  How do I get my G25 coordinates?

  Two routes, both ending at the same service. Route one: order them yourself from Davidski's independent Eurogenes G25 Requests portal (g25requests.app), upload your raw DNA file from 23andMe, AncestryDNA, MyHeritage, FamilyTreeDNA or LivingDNA, pay their €15 fee, and their site states you receive your coordinate row within 2 to 7 days. Route two: order Ancestry Map, our G25 analysis, upload the same raw file at checkout, and we place that request with the same service for you (+€15); our analyst starts on your calculator the moment the coordinates arrive.

• 02

  Are G25 coordinates free?

  Official ones are not: Davidski's G25 Requests service charges €15 per kit, and that fee exists whichever route you take, it is exactly what our add-on passes through. Some free tools output simulated or converted coordinates from other calculators' output; those rows describe the conversion, not your genome, they are not official, and they fail our free authenticity check.

• 03

  Are the coordinates you obtain for me official?

  Yes. We never compute coordinates ourselves, no third party can except that service. Whichever route you take, the coordinates are produced by Davidski's independent Eurogenes G25 Requests service from your raw DNA file. When we obtain them for you, you get the exact same official row you would have received ordering directly, and it is yours to keep and reuse anywhere Global25 coordinates are accepted.

• 04

  How long does it take?

  The provider produces coordinates by hand, so when we obtain them for you it typically takes 2 to 5 days, depending on their queue. Once they arrive, our analyst builds your calculator around them, a person reviews and approves it, and we email you when your report is ready. If you already have your coordinate row, you skip the provider's wait: paste it at checkout and our analyst builds your calculator from there.

• 05

  What does it cost?

  The done-for-you option is a €15 add-on to Ancestry Map, our €29.99 G25 analysis, the fee is a pass-through of the provider's own per-kit charge. It is part of an Ancestry Map order rather than a standalone product: you receive your coordinates and your complete analysis (distances, admixture and PCA across six eras) together.

• 06

  Which testing companies' files work?

  Standard autosomal raw-data exports from 23andMe, AncestryDNA, MyHeritage, FamilyTreeDNA, Living DNA and similar consumer array tests. Whole-genome VCF files are not accepted, and a truncated or edited file is refused before you pay. You can verify your file for free with our file check first.

• 07

  What happens to my DNA file?

  Nothing without your explicit consent. At checkout you are asked, in plain words, to consent to your file being shared with the Global25 provider solely so your coordinates can be produced for this order, the box is never pre-ticked, and without it the order cannot be placed. Your data is stored on EU infrastructure under GDPR, and you can delete it at any time.

• 08

  Do I have to pay €15 again for future analyses?

  No. The coordinates are yours. Your report shows them, and any later Ancestry Map order, or any Global25 tool anywhere, can reuse that row by pasting it. The €15 covers obtaining coordinates once, for the order that buys it.

• 09

  What if my file can't be used?

  We check the file before charging you: an unreadable file, a VCF, or one far below a normal vendor export's marker count is refused at checkout, before any payment. In the rare case the provider cannot process a file that passed our checks, the order is refunded.

• 10

  Is g25requests.app legitimate?

  Yes. It is the request portal of Davidski's independent Eurogenes Global25 project, the origin of every official G25 coordinate row in circulation, and the same service Ancestrify places its own concierge requests with. It is not affiliated with any testing company or with us; we link it because it is the only source of the real thing.

• 11

  Is there a free way to get G25 coordinates?

  Not an official one. Free calculators can convert their own percentages into a row that looks like Global25 coordinates, but that row describes the calculator's output, not your genome, and it drifts from your real position by more than the distances you would be measuring. Our free G25 authenticity check reads a row's numeric fingerprint and flags simulated, converted or rounded rows.

• 12

  Can any service compute my coordinates from my raw file?

  No. The Global25 reference space is private to its author, so only that service can place a new sample into it. A site that computes coordinates from your file is producing an approximation in a space of its own making. That is why Ancestrify never computes them: when we obtain coordinates for you, we send your file to the same portal you would use yourself.

• 13

  What does a real Global25 row look like?

  A label followed by 25 comma-separated decimals, for example a name and then 0.0123, 0.1409, 0.0456 and so on. The portal returns two versions: scaled and unscaled. Most tools, and our analysis, take the scaled row. A row with fewer than 25 numbers, or rounded to two decimals, is not the original.
