Get all the dependant nodes or a root node in a new sub-graph
Hi everybody, I have a graph that contains all the word of a text. This graph is a a directed acyclic graph. I want to reconstruct sequences of this text so I need to get all the nodes and edges that are dependent of a root node or their children. In other words I want a Sub-tree of a tree. I cant get it with a recursive ad-hoc function, using out_neighbours(), but I am wondering if there is another more efficient way to obtain it. I searched in the doc but i don't find it. thanks. -- View this message in context: http://main-discussion-list-for-the-graph-tool-project.982480.n3.nabble.com/...

You want the label_out_component() function: http://projects.skewed.de/graph-tool/doc/topology.html#graph_tool.topology.l... Cheers, Tiago -- Tiago de Paula Peixoto <tiago@skewed.de>
