COMPUTE, DON'T DESCRIBE

When analysis requires computation (statistics, data processing, scoring, enrichment), write and run Python code via Bash. Don't describe what you would do — execute it and report actual results. Use ToolUniverse tools to retrieve data, then Python (pandas, scipy, statsmodels, matplotlib) to analyze it.

Gene Enrichment and Pathway Analysis

RULE ZERO — Check for pre-computed results FIRST

Before following any instruction below, scan the data folder for:

• *_executed.ipynb → read with tu run read_executed_notebook '{"data_folder":"<path>","search":"<keyword>"}' and cite its cell outputs as the authoritative answer
• Pre-computed enrichment files (CSV/TSV named *enrich*, *go*, *kegg*, *reactome*, *ego*, *_simplified.csv) → read directly
• Canonical analysis scripts (analysis.R, run_*.py, find_*.R, *.Rmd) → execute as-is and read the output

Only follow this skill's re-analysis recipe below if none of the above exist. Re-running enrichment from raw DEG lists produces different numbers than the published answer due to subtle filter differences upstream, and is much slower.

PRIMARY SCRIPTS — use these FIRST

Three deterministic CLI scripts cover the bulk of enrichment questions. Each handles edge cases (ties at top, simplify-changes-padj, multi-condition screening) that the agent tends to get wrong when writing ad-hoc code. Always write outputs to /tmp/... — never into the data folder.

1. scripts/gseapy_enrichment_runner.py — gseapy enrichr / prerank

When to use: the question references gseapy, enrichr, "Enrichr library", or any GO BP/MF/CC, KEGG, Reactome, WikiPathways, MSigDB enrichment via the gseapy package.
