4.6 Network Analysis
Cellware provides various tools to extract topological information from the model. These tools can be accessed under Analysis>Network menu.

  1. Stoichiometric matrix: Shows stoichiometric matrix of network, N, which is of size m x n where m and n respectively denote the number of species and the number of reactions of the network. Multiplication by flow vector results the rate equation

  2. Network statistic: Shows network statistics.

  3. Find cycles: Finds independent cycles in the network. Cycles in the network are useful to determine feedback loops. Tarjan algorithm is used to find the cycles and computation takes linear time.

  4. Find path: Finds a shorted path between two nodes. Since our graphs comprise of unweighted edges (link between two nodes), breadth-first search graph algorithm is used to find the shorted path.

  5. Transverse: Finds transversal nodes from a selected node. Transversal nodes are highlighted. Depth-first search graph algorithm is used.

  6. Blast: Finds conserved pathways among networks.
