Hi Cedric,
I have been trying to use a program called Tulip to visualise my graphs, 
it claims to work up to millions of nodes, but as yet I still get crashes 
for relatively small graphs. My main problem has been that all my machines 
with enough RAM are remote and the x-connection is too slow. I have put 
some more RAM in my desktop but now the graphics card seems to struggle. 
Waiting for a new graphics card ... Tulip does support batch mode, so I 
could run on a big memory machine and output hardcopy, but I haven't had a 
chance to really learn it interactively yet.

I'll let you know if I have any success.

How big a graph can you look at with cytoscape? I haven't tried that.

Best,

Adam.
