Functional Enrichment Analysis (GSEA + ORA)

Functional Enrichment Analysis (GSEA + ORA) is a skill for Claude Code, Codex from TianGzlab/OmicsClaw. It costs 11 tokens per session (5,026 once invoked), scanned A, original, Apache-2.0.

A workflow that interprets lists of genes that change between conditions by linking them to biological pathways and processes. It uses GSEA, which examines all ranked genes, and ORA, which tests a selected list of significant genes.

In plain words
What is it for?
Analysing differential-expression results, finding affected pathways, interpreting gene lists, and preparing biological summaries for publications or validation.
Why use it?
It translates statistical gene-expression results into biological meaning, helping explain what systems or processes may be affected.

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

Functional Enrichment Analysis (GSEA + ORA) 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 12d 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.

Functional Enrichment Analysis

Translate differential expression results into biological insights using GSEA and ORA.

When to Use This Skill

Use this skill after completing differential expression analysis to identify enriched pathways and biological processes.

Use when:

  • ✅ You have DE results with fold changes and p-values
  • ✅ Want to answer: "What pathways or processes are affected?"
  • ✅ Need to interpret gene lists in biological context
  • ✅ Preparing results for publication or validation

Two complementary methods: GSEA (primary, uses all ranked genes, detects coordinated changes) and ORA (secondary, uses significant gene list, validates GSEA). Default recommendation: Run GSEA unless user specifically requests ORA or has only a gene list (no fold changes).

See references/gsea_ora_comparison.md for detailed method comparison.

Quick Start (Example Data)

Test this skill with real DE results in ~2 minutes:

# Load example DE results from airway dataset (dexamethasone treatment)
source("scripts/load_example_data.R")
de_results <- load_airway_de_results()  # Auto-installs packages (~1-2 min, ~40MB)

# Load required packages and scripts
library(clusterProfiler)
library(msigdbr)
source("scripts/prepare_gene_lists.R")
source("scripts/get_msigdb_genesets.R")
source("scripts/run_gsea.R")
source("scripts/generate_plots.R")
source("scripts/export_results.R")

# Run GSEA workflow
ranked_genes <- create_ranked_list(de_results)
term2gene <- get_msigdb_genesets("human", c("H"))  # Hallmark pathways only for speed
gsea_result <- run_gsea(ranked_genes, term2gene, n_perm = 1000)
generate_all_plots(gsea_result)
export_all(gsea_result, ranked_genes, output_prefix = "quick_test")

What you get:

  • Dataset: Human airway smooth muscle cells, dexamethasone treatment vs untreated
  • Expected results: ~5-10 significant Hallmark pathways (Inflammatory Response, TNF-alpha signaling, Interferon response)
  • Outputs: CSV results, SVG/PNG plots, RDS objects, markdown summary

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.
