The skill searches ArrayExpress and BioStudies public APIs to retrieve expression experiments and metadata. It applies cross-database discovery to find RNA-seq and microarray studies, centralizing scattered datasets for streamlined comparative research.

Parsing SDRF sample metadata involves retrieving SDRF files via the ArrayExpress API to extract structured sample information. This prepares associated files and metadata for assembling expression matrices in downstream cross-study reanalysis.

Yes, cross-study reanalysis is possible by assembling expression matrices and metadata retrieved from multiple ArrayExpress experiments. This enables comparative analysis across different RNA-seq and microarray datasets using centralized discovery.

Yes, the tool supports both RNA-seq and microarray studies. It retrieves expression experiments and metadata across ArrayExpress and BioStudies databases, enabling cross-database discovery for both data types.

API errors during data retrieval are handled gracefully with built-in validation and fallback mechanisms. This ensures the metadata extraction and SDRF parsing pipeline remains robust even when public API requests encounter issues.
