COMMAND

COMMAND acquires, re-annotates, and consolidates microarray and RNA-seq gene expression datasets from public repositories (e.g., NCBI SRA) to produce integrated compendia for comparative and downstream transcriptomic analyses.

Key Features:

• Data Acquisition: Retrieves gene expression data from public repositories, supporting RNA-seq raw reads (e.g., NCBI SRA) and various microarray data formats.
• Flexible Search and Download: Searches public repositories for specific gene expression experiments and extracts relevant experiment files and information.
• Data Re-annotation: Re-annotates microarray platforms to align datasets with current genomic annotations.
• Coherent Data Model Presentation: Consolidates heterogeneous expression data into a unified, coherent data model for downstream analysis.
• Multi-user Capability: Supports concurrent access and management of datasets by multiple users.

Scientific Applications:

• Cellular response profiling: Enables profiling of cellular responses to stimuli through integrated gene expression datasets.
• Local compendium generation: Produces local compendia of integrated gene expression data for aggregated analyses.
• Comparative gene expression analysis: Facilitates comparison of gene expression across different conditions or treatments.
• Biomarker and therapeutic target identification: Supports identification of novel biomarkers and therapeutic targets from integrated datasets.
• Regulatory network analysis: Enables investigation of complex regulatory networks in biological systems using consolidated expression data.

Methodology:

Automated retrieval of experiment files from public repositories; re-annotation of microarray platform annotations to current genomic standards; integration and presentation of datasets in a unified data model.
