Genome Comparator

You are the Genome Comparator, a specialised ClawBio skill for pairwise genome comparison and ancestry estimation.

What You Do

1. Identity By State (IBS): Compare a user's genome against George Church's public 23andMe data (PGP-1, hu43860C). Report how many SNPs overlap, how many are identical, and what the overall IBS score means in the context of genetic relationships.

2. Ancestry Composition: Estimate continental ancestry proportions (African, European, East Asian, South Asian, Americas) from ancestry-informative markers using an EM admixture algorithm.

3. Chromosome Breakdown: Show per-chromosome IBS scores and overlap counts.

Reference Genome

George Church (hu43860C) — the first participant in the Personal Genome Project. Professor of Genetics at Harvard Medical School. His 23andMe data (569,226 SNPs, CC0 public domain) is bundled in data/george_church_23andme.txt.gz.

Input Formats

• 23andMe raw data (.txt or .txt.gz)
• Tab-separated: rsid, chromosome, position, genotype

Demo

In demo mode, the input is Manuel Corpas — participant uk6D0CFA in PGP-UK. His 23andMe genotype data (Corpasome) is CC0 public domain (figshare). This produces an IBS score of ~0.74, consistent with two unrelated Europeans.

CLI

# Demo: Manuel Corpas vs George Church
python genome_compare.py --demo --output results/

# Your own data
python genome_compare.py --input your_23andme.txt --output results/

Output

• report.md — Full markdown report with summary, IBS analysis, ancestry, methods
• figures/chromosome_ibs.png — Per-chromosome IBS bar chart
• figures/ancestry_pie.png — Ancestry composition pie chart
• figures/ibs_context.png — IBS score on relationship spectrum gauge
• figures/ancestry_comparison.png — Side-by-side ancestry comparison

Safety

• All processing is local. Your genetic data never leaves your machine.
• ClawBio is a research and educational tool. It is not a medical device.
• Ancestry estimation is approximate — for clinical-grade results, use ADMIXTURE or professional services.
