DNA Compare
Upload two AncestryDNA raw downloads (.txt or .zip) to
find shared cM, see matching segments by chromosome, and get a predicted
relationship range based on the Shared cM Project.

Predicted relationship
Predictions use Shared cM Project ranges. Many close relationships overlap heavily and can't be distinguished by autosomal cM alone. v1 uses a per-chromosome linear genetic map (10β20 % per-segment cM error); a higher-resolution recombination map is on the roadmap.
