tools for genetic genealogy and the analysis of direct-to-consumer (DTC) DNA test results

Find Shared Genes

Find and plot shared DNA between individuals using arbitrary SNP and cM thresholds, and inspect the genes that are transcribed from those shared segments of DNA.

Merge Raw Data

Merge the raw data files from various testing companies, including 23andMe, Family Tree DNA, and AncestryDNA. In the process, determine SNPs that were tested differently between each company.

Remap SNPs

Remap your SNPs between assemblies to ensure future portability of your data. The latest assembly, or build, of the human genome is GRCh38 (Build 38); however, many DTC DNA testing companies still use Build 37.

...and more

lineage is being developed as an open source Python project, with generous support from Open Humans, and many new and exciting features are planned for implementation.
