Dear all,
I have a bipartite graph, directed and with weightened edges. It is very large, I believe 36k nodes and 52k edges. I am trying to make a projection of it, but I could not find any function or way to do so with graph-tool. Is there any way I am not aware of? If there is no current way, where would you recommend try with such a big graph? I am currently trying to run this on a 8gb RAM 2012 macbook pro 15` (2.2 ghz or something like that).
I started of from (1) Gephi plugin ( https://marketplace.gephi.org/plugin/multimode-networks-transformations-2/), which after running for a couple hours almost froze my computer and output no graph (I had to force quit it). My second attempt was (and is) on igraph ( http://igraph.org/python/doc/igraph.Graph-class.html#bipartite_projection )
I came across this post: http://stackoverflow.com/questions/606516/python-graph-library
And read about graph-tool and how efficient it is compared to the igraph and networkx (which I was about to try but given up when I saw the time table).
Thank you for your attention,
Hi,
Could you specify a particular projection?
`graph_tool.sfp_layout` does a pretty good job for a variety of layouts. It is also easy to setup custom projection through x, y and z propertymaps and matplotlib.
Hope this helps,
Guillaume

Bipartite projection is currently not implemented, but this is a very easy one. Just open a ticket for it on the website and I'll include an implementation when I have some time.

Dears,
Thank you for the layout information Guillaume, this will come to use in due time, although it wasn't really what I was after :-)
Tiago Peixoto, I opened an issue here: https://git.skewed.de/count0/graph-tool/issues/196 linked to this discussion.
Thank you both for the quick reply, and the interest on implementing this feature.
Best Regards,

I thought about bringing this discussion here from my message on igraph mailing list since it relates to this feature:
It seems to me (I may be badly mistaken) that current bipartite projection by weighted graphs do not account for the original graph weights.
To contextualize, here a bad hand draw example: https://www.dropbox.com/s/fl69kekipqksd4i/Screenshot%202014-12-01%2012.51.22...
I am interested on both values (red circle and orange square), however igraph documentation only accounts (or at least suggest to on the documentation) for the orange one: http://igraph.org/python/doc/igraph.Graph-class.html#bipartite_projection
I checked networkX as well but I couldn't find anything about weighted bipartite graph projections: http://networkx.lanl.gov/archive/networkx-1.6/_modules/ http://networkx.lanl.gov/archive/networkx-1.6/_modules/networkx/algorithms/bipartite/projection.html networkx/algorithms/bipartite/projection.html http://networkx.lanl.gov/archive/networkx-1.6/_modules/networkx/algorithms/bipartite/projection.html
Is it possible for this to be taken into account when the posted 'issue' is tackled?
Thank you,
Carlos A.

Admin,
Is the feature to get the bipartite projection implemented now in graph tools? If yes, Can you please provide the link as I am unable to find it? Would be of great help.
Thanks in advance, Aditya

Not yet. If you want to be informed when it is, follow this issue:

Yes I guess I missed the "Bipartite" part of the message :p
