The skill is primarily documentation and examples for accessing public NCBI GEO data. I confirmed the plaintext FTP guidance as a medium concern because it can expose downloads to tampering. The remaining static findings are false positives involving public URLs, Markdown fences, placeholder keys, local data saves, and GEO identifiers.

What You Can Build

Find disease expression studies

Search GEO for human disease datasets and summarize candidate GSE records for review.

Prepare expression matrices

Download a GEO Series, inspect sample metadata, and extract a matrix for downstream analysis.

Compare studies for a gene

Locate platform probes for a gene and compare expression summaries across selected studies.

Try These Prompts

Search for datasets

Find NCBI GEO datasets about [condition] in [organism]. Return likely GSE accessions, study types, sample counts, and why each result is relevant.

Retrieve study metadata

Use GEO guidance to review [GSE accession]. Summarize the title, organism, platform, samples, experimental design, and available file types.

Plan expression analysis

Create a workflow for downloading [GSE accession], extracting the expression matrix, separating control and treatment samples, and checking data quality.

Design a meta-analysis workflow

Plan a reproducible GEO meta-analysis for [gene or pathway] across [GSE accessions]. Include metadata harmonization, probe mapping, normalization checks, and statistical cautions.

Best Practices

Set an Entrez email address and respect NCBI rate limits for every automated query.
Check sample metadata, platform annotation, and processing methods before comparing expression values.
Cache large downloads locally and record dataset accessions, versions, and citations.

Avoid

Do not assume all GEO studies use comparable normalization or experimental design.
Do not download large supplementary files without checking disk space and file purpose.
Do not treat probe identifiers as gene symbols without platform-specific annotation mapping.

Frequently Asked Questions

What is NCBI GEO?

NCBI GEO is a public repository for gene expression and functional genomics datasets.

Can this skill download GEO files?

Yes. It provides workflows for GEOparse, E-utilities, and direct file downloads from GEO locations.

Does it support RNA-seq and microarray data?

Yes. The guidance covers GEO study searches and file handling for both sequencing and array experiments.

Does it perform final statistical interpretation?

No. It can outline analysis steps, but results need statistical and biological review.

What tools does it expect?

The examples use Python libraries such as GEOparse, Biopython, pandas, scipy, and visualization packages.

How should I handle API keys?

Use NCBI API keys only when needed, store them securely, and avoid committing them to shared files.
