7 articles on raw-dna — ancient-DNA research written up for readers who want the evidence, not just the headline.
23andMe does not produce G25 coordinates — but its raw data file is a good starting point. How to download it, what the v5 chip actually covers, and the exact route from file to coordinate row.
AncestryDNA does not produce G25 coordinates — but its raw data download is the input that becomes one. The emailed-confirmation download flow, what the file covers, and the route from file to coordinate row.
MyHeritage does not produce G25 coordinates — but its raw data export is the input that becomes one. The download flow, the low-pass WGS caveat that costs people their haplogroups, and the route to a coordinate row.
FamilyTreeDNA does not produce G25 coordinates — but a Family Finder raw data export is the input that becomes one. Which download to pick, what the file covers, and the route to a coordinate row.
LivingDNA does not produce G25 coordinates — but its raw data download is the input that becomes one. Where the download lives, what the file covers, and the route to a coordinate row.
Where Global25 coordinates come from, how to get them whether you tested with 23andMe, AncestryDNA, MyHeritage, FamilyTreeDNA or LivingDNA, and how to tell a real coordinate row from a simulated one.
How relative verification from raw DNA files actually works — the kinship coefficient, half-identical and fully-identical segments, telling a parent from a sibling, and where the signal honestly ends.
