  • Interactive 3D network visualization (rotate, zoom, etc.)
    • 2D representation
    • Stereo representation (side by side)
    • 3D beamer mode (condensed side by side stereo, converted for shutter glasses)

  • Ageing-related network data (AgeFactDB)
    • Lifespan observations
    • Ageing factors
    • Augmentation nodes (e.g.: allele types, citations)
  • Augmentation with external domain knowledge
    • Gene Ontology (GO)
    • KEGG Pathways
  • Genes of interest analysis (e.g.: differentially expressed genes)
  • Scripting language
    • JANet-specific API


The viewer can be started directly from the server at

or the source code can be downloaded for local installation

For a local installation there are two options:

  1. Extract the archive somewhere in the file system.
  2. Install a web server locally and extract the archive somewhere below the server root directory.
  3. Install a neo4j server
  4. python 3.5 or above is required.
