COnTORT

COnTORT retrieves and organizes gene expression datasets from the NCBI Gene Expression Omnibus (GEO) for specified organisms to support transcriptomic analyses.


Key Features:

  • Data Retrieval: Automates downloading of all available gene expression data from GEO for a specified organism, including raw and processed datasets.
  • Metadata Compilation: Collects associated metadata such as sample conditions, platform types, and study annotations.
  • Output Format: Compiles expression data and metadata into text files formatted for downstream bioinformatics analyses.

Scientific Applications:

  • Comparative Transcriptomics: Allows comparison of gene expression profiles across studies or experimental conditions within the same organism.
  • Meta-Analyses: Aggregates datasets from multiple GEO studies to support meta-analysis across experiments.
  • Data Integration: Facilitates integration of GEO-derived transcriptomic data with other genomic or proteomic datasets for multi-omics analyses.

Methodology:

Queries the GEO database with organism-specific search criteria, retrieves matching datasets and their metadata, and organizes them into text files.
