BioVenn

BioVenn generates area-proportional Venn diagrams to visualize and quantify overlaps among biological identifier lists for comparative genomics analyses.

Key Features:

• Area-proportional Venn diagrams: Generates Venn diagrams with circle areas proportional to dataset sizes to represent size relationships among datasets.
• Dataset-overlap representation: Represents each dataset as a circle and overlap regions as shared elements across datasets.
• Identifier support: Supports a wide array of biological identifiers from numerous databases.
• Subset identifier lists: Outputs lists of identifiers for each overlap subset produced by the analysis.
• Database hyperlinks: Includes hyperlinks from output identifiers to corresponding entries in supported biological databases when available.
• ID mapping to Ensembl: Maps Affymetrix and EntrezGene identifiers to Ensembl gene identifiers for cross-platform interoperability.
• Image export formats: Exports graphical outputs as standalone SVG and PNG images suitable for downstream processing.
• Batch-ready exports: Produces outputs suitable for batch processing of larger datasets.

Scientific Applications:

• Comparative analysis of identifier lists: Compare gene or other biological identifier lists across experiments to identify shared and unique elements.
• Overlap visualization: Visualize overlaps among multiple genomic datasets using area-proportional representation.
• Cross-platform integration: Integrate datasets from different platforms by mapping Affymetrix and EntrezGene identifiers to Ensembl genes.
• Downstream computational workflows: Provide overlap-derived identifier lists and image exports for downstream computational analyses.

Methodology:

Generates area-proportional Venn diagrams, derives identifier subsets with hyperlinks to supported databases, maps Affymetrix and EntrezGene identifiers to Ensembl genes, and exports results as SVG and PNG images suitable for batch processing.
