PLINK / bed·bim·fam — client-side, nothing leaves your browser

Strata — a core sample
through your genome

Upload a reference panel (e.g. the Allen Ancient DNA Resource, 1000 Genomes, or any custom PLINK trio) and a query genome. Strata matches shared markers, lets you choose which reference populations act as ancestry sources, and projects each of your samples onto them — rendered as a drillable stratigraphy column you can re-cut, re-sort, and export.

Reference panel

The panel whose populations become your ancestry "layers" — e.g. allen_1240K_public.bed/.bim/.fam, 1000 Genomes, or your own labelled trio. Population labels are taken from the FID column of the .fam file.
