Subgraph

[ashwani sharma]

Hi Friends,

I have a problem related to subgraph. Lets say I have 2 files one parent.txt (which is for parent graph) and a subgraph.txt (which is for subgraph).
I have been using subgraph(G,nbunch,copy=true) function to derive a subgraph but it generates subgraph between nodes of subgraph.txt file only but I need to generate a graph between all nodes which are connected to all nodes from subgraph.txt file.


Any help will be appreciated

Regards,
Ashwani

Something like this should work...

#set up G
S=nx.Graph()
for n in nbunch:
S.add_edges_from( (n,nbr) for nbr in G[n] )

I have a graph G, I can use list(nx.connected_component_subgraphs(G)) to get connected subgraph g1,g2...

but how can i reverse that progress,that is to say, if i have subgraph g1,g2,.. how can i get the graph G?

Maybe one of these operators is what you are looking for.
