[igraph] Beginner in igraph

[Akshata Udyavar]

Hi everyone -

I am beginning to use igraph to do some analysis on pre-made protein-protein interaction networks either from gene _expression_ datasets or public databases (from Cytoscape). Is there a way I can import this interactome into the igraph and do analysis thereof? How many nodes and edges can igraph handle? Thanks.
