Usecase/Data

• Cytoscape
  • kozo-ni(kozo-ni@…)
    • usecase
      • retrieve an organism's all metabolic reactions from KEGG
      • convert node format from [compound -> enzyme -> compound] to [compound -> compound] or [enzyme -> enzyme] like following paper
        •  http://bioinformatics.oxfordjournals.org/cgi/content/full/22/14/1767
      • calculate betweeneth and find bottlenecks (currently I use CentiScaPe? plugin or igraph[R library])
      • map gene expression to enzyme
    • data
      • affymetrix gene-chip expression data
    • functionality needs
      • get an organism's all metabolic reactions from KEGG
      • draw enzyme or compound centric network. (In enzyme centric network, enzyme nodes share a common compound. In compound centric network, compound nodes share a common enzyme.)
• ??
  • 1000genomes.org: displaying SNP locations of the individuals (which reference ?) ? status on dbSNP ? Is it a 'true' snp : the user wants to 'see' the short reads overlapping this variation

• E-Cell 3D
  • show dynamics of cellular simulations as well as the network
  • debug a simulation model - a molecule could be depleted or too concentrated, steady-state (balanced flux), rhythms
  • looking at the overall behavior

• Genome Projector
  • look at a feature of interest from several different perspectives (zoom level + context)
  • overlay data

Future directions

• semantic zooming
  • need for queries (DAS?) to define semantic abstraction of data
  • server-side implementation to handle semantic abstraction level of returned data
