bio-causal-genomics-fine-mapping

bio-causal-genomics-fine-mapping is a skill for Claude Code, Codex from PKU-YuanGroup/OpenAI4S. It costs 161 tokens per session (9,641 once invoked), scanned A, a copy of bio-causal-genomics-fine-mapping, MIT.

A research workflow for fine-mapping GWAS results, meaning narrowing a broad genetic signal to a smaller set of variants that may cause it. It uses statistical methods such as SuSiE, FINEMAP, and related tools with genetic linkage information.

In plain words
What is it for?
Use it to analyse lead SNPs, combine summary statistics with a linkage reference or individual genotypes, calculate posterior inclusion probabilities, build credible sets, and assess whether the linkage data fit the analysed population.
Why use it?
A GWAS association usually points to a region containing many nearby variants rather than identifying one causal change. Fine-mapping ranks candidates and creates credible sets, which are groups expected to contain the causal variant with a chosen probability.

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-causal-genomics-fine-mapping 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 13d ago.

The scan reads SKILL.md. This mod also ships 2 executable files (scripts/finemap_pipeline.sh, scripts/susiex_multiancestry.sh), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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 — 444 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Version Compatibility

Reference examples tested with: susieR 0.12.27+, coloc 5.2.3+, FINEMAP 1.4.2+, PolyFun (head of omerwe/polyfun 2024), PAINTOR V3.0, SuSiEx (head of getian107/SuSiEx), DAP-G (head of xqwen/dap), pyfocus 0.8+, R 4.3+, PLINK 1.9 / 2.0.

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

  • R: packageVersion('susieR') then ?susie_rss to confirm argument names (e.g., prior_weights vs prior_variance semantics)
  • CLI: finemap --help, SuSiEx --help, PAINTOR --help, dap-g --help to confirm flags
  • Python: polyfun.py --help

If a call throws an error about an argument that no longer exists, introspect the installed function and adapt rather than retrying.

Fine-Mapping

"Narrow my GWAS locus to the variants likely to be causal" -> Fit a sparse Bayesian regression that propagates LD into posterior inclusion probabilities (PIPs) and credible sets, then validate that credible sets correspond to physically reasonable haplotypes given the LD reference.

  • R (summary statistics + LD): susieR::susie_rss(z, R, n, L=10) + estimate_s_rss LD diagnostic
  • R (individual-level genotypes): susieR::susie(X, y, L=10)
  • CLI (shotgun stochastic search): finemap --sss --in-files master.z --n-causal-snps 5 --prob-tol 0.001
  • CLI (cross-ancestry joint): SuSiEx --sst_file=eur.sst,eas.sst --n_gwas=N1,N2 --ref_file=eur.bim,eas.bim --ld_file=eur_ld,eas_ld --chr_col=1,1 --snp_col=2,2 --bp_col=3,3 --a1_col=4,4 --a2_col=5,5 --eff_col=6,6 --se_col=7,7 --pval_col=8,8 --chr=<chr> --bp=<start,end> --out_dir=<dir> --out_name=<name> (column-number flags and --ld_file are required; populations are assigned by the ORDER of the comma-separated --sst_file/--n_gwas/--ref_file/--ld_file lists, not a --pop flag; see SuSiEx --help)
  • Python (functional priors): polyfun.py --compute-h2-L2 -> per-SNP priors -> susie_rss with prior_weights=
  • Python (TWAS fine-mapping): focus finemap on gene-level Z-scores

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.
