Hi,
I can reproduce this with my R on Linux Mint (with all updates). R
throws the same error, the file opens fine in visone.
I also tried to save the graph as GML in visone. With this file
igraph::read.graph terminates with another error:
--- snip ---
Error in read.graph.gml(file, ...) :
At core/io/gml.c:214 : Parse error in GML file, line 1 (syntax error,
unexpected LISTCLOSE, expecting KEYWORD), Parse error
--- snip ---
Is this now related to igraph or to visone? It seems that igraph is not
able to read graphs exported from visone, reason unknown to me.
Might be related to this, but I also found a similar problem reported
for Cytoscape. Since both are Java-based spplications, could this be
caused by a malfunctional Java library?
Best,
Kimmo
