Question

Does a simple UNION operation on node sets and edge sets suffice for combining several pathways to a global metabolic network?

Method

  • Download pathway descriptions as KGML -> eco00260 and eco00270.
  • Convert to substance-reaction graphs -> eco00260_graph and eco00270_graph.
  • Combine the pathways via UNION operation -> union_graph.
  • Subtract the individual parts of the resulting network. Firstly, without subtracting nodes, to leave any surviving edges -> subtracted_graph_keeping_nodes. Secondly, with subtracting nodes -> subtracted_graph_deleting_nodes.
  • Print any edge that remains in subtracted_graph_keeping_nodes. Print any node that remains in subtracted_graph_deleting_nodes.

Conclusion

UNION is indeed correctly implemented and fit for the task of combining several pathways to a global network.
