**Drug versus Disease (DvD)** provides a pipeline, available through **R** or **Cytoscape**, for the comparison of drug and disease gene expression profiles from public microarray repositories. Negatively correlated (enriched) profiles can be used to generate hypotheses of drug-repurposing whilst positively correlated (enriched) profiles may be used to infer side-effects of drugs. DvD provides a pipeline for comparing drug and disease signatures with dynamic access to databases Array Express, GEO and data from the Connectivity Map.
