About:
GDAT is a specialized macOS application designed for genealogical DNA analysis. It allows users to upload raw DNA data from major testing services and perform advanced triangulation and segment analysis. The tool's core value is helping family historians identify common ancestors and validate relationships through genetic evidence.

Key Features:

Automated triangulation of DNA segments across multiple test kits
Chromosome browser and segment analysis tools
Supports raw data from AncestryDNA, 23andMe, MyHeritage, and FamilyTreeDNA
Integration with genealogical research workflows and family trees

Use Cases:

Identifying unknown ancestors or biological parents through DNA matches
Validating genealogical research by confirming shared DNA segments

Alternatives:

DNA Painter – Web-based tool for segment mapping; GDAT is a native macOS app with more automated triangulation features.
GEDmatch – Web platform with extensive tools but requires manual analysis; GDAT offers a more streamlined desktop experience.
