bio-data-visualization-manhattan-qq-locuszoom

bio-data-visualization-manhattan-qq-locuszoom is a skill for Claude Code, Codex from GPTomics/bioSkills. It costs 95 tokens per session (4,901 once invoked), scanned A, original, MIT.

A guide to genome-wide association plots, which show statistical links between genetic variants and traits. It covers Manhattan, QQ, Miami, and locuszoom-style views, including nearby genes and linkage information.

In plain words
What is it for?
Use it to visualize GWAS, TWAS, PWAS, or QTL summary statistics, label lead variants, and examine regional associations.
Why use it?
It helps reveal genome-wide peaks, check whether statistical results are inflated, compare two traits, and inspect a specific genomic region in context.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

bio-data-visualization-manhattan-qq-locuszoom scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 322 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Version Compatibility

Reference examples tested with: qqman 0.1.9 (R), CMplot 4.5+ (R), matplotlib 3.8+, pandas 2.2+, scipy 1.12+, plinkQC 0.3+. For locuszoom-style: locuszoomr 0.3+ (R) or pyranges + matplotlib.

Before using code patterns, verify installed versions match. If versions differ:

  • Python: pip show <package> then help(module.function) to check signatures
  • R: packageVersion('<pkg>') then ?function_name to verify parameters

If code throws ImportError, AttributeError, or TypeError, introspect the installed package and adapt the example to match the actual API rather than retrying.

Manhattan, QQ, and Locuszoom Plots

"Plot my GWAS results" -> Render per-variant -log10(p) across the genome (Manhattan), compare expected vs observed p quantiles (QQ + λGC), overlay two traits with mirrored axes (Miami), and zoom into a locus with LD-colored points + recombination rate + gene track (locuszoom). The choices that matter: significance thresholds, axis truncation for ultra-significant peaks, lead-SNP labeling, and LD reference selection for regional plots.

  • R: qqman::manhattan / qqman::qq (Turner 2018), CMplot::CMplot, locuszoomr::locus_plot
  • Python: matplotlib + pandas for custom; assocplots for ready-made

The Single Most Important Modern Insight -- The Threshold Is Always Conditional

The "genome-wide significant" line at p < 5e-8 (Pe'er 2008 Genet Epidemiol 32:381) is calibrated for European-ancestry common-variant GWAS assuming ~1M effectively independent tests. It is the wrong threshold for:

  • Whole-genome sequencing including rare variants (~5e-9 EUR, ~1e-9 AFR; Pulit 2017 Genet Epidemiol 41:145; Xu 2014 Genet Epidemiol 38:281)
  • Non-European ancestry with different LD structure (typically more stringent)
  • TWAS / PWAS with ~20,000 tested genes (Bonferroni 2.5e-6)
  • Multi-ethnic meta-analysis (5e-9 by convention for trans-ancestry)
  • Burden / SKAT rare-variant tests (per-gene; ~2.5e-6)
  • Locus-wise fine-mapping (within-locus testing, no genome-wide correction needed)

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

bio-data-visualization-manhattan-qq-locuszoom is a skill published in the GitHub repository GPTomics/bioSkills (1,201 stars, last pushed 27d ago), licensed MIT. It adds 95 tokens to every session and 4,901 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
