What problem does it solve?
This Skill provides programmatic access to the NCBI Gene Expression Omnibus (GEO) database, enabling users to find, download, and analyze gene expression and genomics datasets.
Core Features & Use Cases
- Search & Retrieve: Find and download microarray and RNA-seq datasets (GSE, GSM, GPL) using various search criteria.
- Data Parsing: Utilize libraries like GEOparse and Biopython to parse SOFT/MINiML files and extract expression matrices.
- Analysis: Perform quality control, differential expression analysis, and clustering on downloaded data.
- Use Case: A researcher needs to find all human RNA-seq datasets related to Alzheimer's disease, download their expression matrices, and perform a meta-analysis to identify commonly dysregulated genes.
Quick Start
