cdlib exposes a few utilities to manipulate graph objects generated with igraph and networkx.

Graph Transformation

Transform igraph to/from networkx objects.

convert_graph_formats(graph, desired_format, …) Converts from/to networkx/igraph

Identifier mapping

Remapping of graph nodes. It is often a good idea - to limit the memory usage - to use progressive integers as node labels. cdlib automatically - and transparently - makes the conversion for the user, however, this step can be costly: for such reason the library also exposes facilities to directly pre/post process the network/community data.

nx_node_integer_mapping(graph) Maps node labels from strings to integers.
remap_node_communities(communities, node_map) Apply a map to the obtained communities to retreive the original node labels
