Compare your genome to George Church (PGP-1) and estimate ancestry composition

General

What this skill does


# 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](https://pgp.med.harvard.edu/). 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](https://my.personalgenomes.org.uk/profile/uk6D0CFA) in [PGP-UK](https://www.personalgenomes.org.uk/). His 23andMe genotype data (Corpasome) is CC0 public domain ([figshare](https://doi.org/10.6084/m9.figshare.92682)). This produces an IBS score of ~0.74, consistent with two unrelated Europeans.

## CLI

```bash
# 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.

Draws the 12 Houses of the Zodiac Tarot spread to inject entropy into planning when prompts are vague, ambiguous, or casually delegated. Interprets the spread to guide next steps. Use when the user says 'let fate decide', 'YOLO', 'whatever', 'idk', or other nonchalant phrases, makes Yu-Gi-Oh references, or when you are about to arbitrarily pick between multiple reasonable approaches. Prefer over ask-questions-if-underspecified when the user's tone is casual or playful rather than precision-seeking.
