Hello,
I'm trying to save the content of variable GG into an ASCII format file but I'm getting the following error
Error using graph/subsref (line 7)
Indexing not supported.
Error in dlmwrite (line 166)
rowIsReal = isreal(m(i,:));
so=[1 1 1 2 2 2 2 3 3 3 5];
ta=[2 3 4 3 4 5 6 6 7 5 7];
GG=graph(so,ta);
dlmwrite('graph.txt',GG)
Could you please teach me how to avoid this error?

dlmwrite('graph.txt',GG.Edges.EndNodes)
However in general there can be additional attributes associated with a graph, and you might want to
dlmwrite('graph.txt', table2array(GG.Edges))

dlmwrite has an append option, but dlmwrite is really only for numeric data.

It seems that writetable doesn't have an append option. Will it be efficient to save Nodes and Edges in two different files?
