In case it's helpful, the practical result is that I can't accomplish what I want to do: namely, select certain edges based on properties expressed as attributes, and modify or remove just those edges. If there is another way to accomplish this, then I'd be grateful to learn.

Hi,
Can you provide a sample dot file with this problem?

Thanks

sure, see below: simple 3-node graph.

the edges show up in the color specified (red, black, blue), but edge properties are not viewable/editable in the Laboratory or anywhere else.

thanks!

graph G {
	0[label="1", elevation="524.696", measured="false"];
	1[label="11", elevation="603.338", measured="false"];
	2[label="2", elevation="524.696", measured="false"];
	0--1 [label="10", diameter="8", measured="false", color="red"];
	1--2 [label="11", diameter="8", measured="false", color="blue"];
	0--2 [label="12", diameter="8", measured="false", color="black"];
}

@samhatchett Thanks

Just ran across this. I guess the short term answer is to switch to a different graph format where Gephi supports attributes on edges.

I'm trying GEXF, which seems to be more successful so far.

This is fixed but due to some other error we had to change the edge parsing a bit. Edges like 0--1 won't work anymore. The spaces are necessary: 0 -- 1 works.
