[igraph] Igraph and SONIA

[Lorenzo Isella]

Dear All,
I am not experienced at all about the various formats for storing 
networks, but someone told me that the SONIA format is quite common for 
visualizing/representing dynamical networks.
I found several online resources telling how to save an igraph graph in 
the SONIA format, e.g.

http://bit.ly/fTqhQ and
http://cran.r-project.org/web/packages/igraphtosonia/

but can I also go the other way around (reading a graph stored in the 
SONIA format as an igraph graph)? Or am I asking a question which does 
not make sense as igraph would (perhaps) have troubles in dealing with 
nodes/edges specified as having a finite lifetime?
Many thanks

Lorenzo
