Microarray Retriever

Microarray Retriever retrieves microarray datasets from the Gene Expression Omnibus (GEO) and ArrayExpress repositories to support gene expression meta-analysis.

Key Features:

• Cross-repository access: Queries and retrieves datasets from both GEO and ArrayExpress to aggregate microarray data across repositories.
• Complex query capability: Supports detailed search criteria to filter datasets by specified experimental parameters.
• Batch retrieval and download: Enables retrieval of multiple datasets at once and organizes them into a structured archive for download.
• Publication linkage: Retrieves microarray datasets associated with published articles to connect data with the supporting literature.

Scientific Applications:

• Gene expression meta-analysis: Enables combination of expression data from multiple studies to support cross-study analyses and increased statistical power.
• Genomics, molecular biology, and systems biology research: Facilitates aggregation of relevant microarray datasets for investigations in genomics, molecular biology, and systems biology.

Methodology:

Users submit search criteria to query the GEO and ArrayExpress databases; the system processes those queries to identify matching datasets and prepares the selected data for organized download.
