Error saving any dynamic network in gexf format #1426
Comments
Hi, there is currently a known bug when converting weight column to dynamic from Data laboratory. |
Could you explain a bit what you mean? |
Yeah, I understand you want to create a dynamic network with dynamic weight and fill it manually from data laboratory. But I think you can workaround this problem by loading a gexf file without nodes or edges, but with dynamic weight, which works correctly. Try loading this gexf: <gexf xmlns="http://www.gexf.net/1.1draft"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.gexf.net/1.1draft
http://www.gexf.net/1.1draft/gexf.xsd"
version="1.1">
<graph mode="dynamic" defaultedgetype="directed">
<attributes class="edge" mode="dynamic">
<attribute id="weight" title="Weight" type="float"/>
</attributes>
<nodes>
</nodes>
<edges>
</edges>
</graph>
</gexf> |
But even if I load your minimal gexf, add a dynamic edge and try to save it, the same problem persits, i.e. gexf file ands in the middle of 1st edge definition
Could you give me an example how the gexf file should look with dynamic edge weight with |
I have this same issue when using dynamic weights for both DateTime and Double. Do you know when this is expected to be fixed? |
@Jonty800 This should be fixed in 0.9.2 release, and probably as a 0.9.1 update maybe in 1-2 months. |
Is this fixed? When I try to layout a graph with dynamic edge weights I get the following error message java.lang.IllegalStateException: The weight is dynamic, call getWeight(timestamp) or getWeight(interval) instead at java.util.concurrent.Executors$RunnableAdapter.call(Unknown Source) |
Not fixed yet, sorry, but it's in the list of next issues to fix. |
Is there a way to visualize dynamic networks with time varying edge weights that doesn't crash the software? My data loads fine but as soon as I try to graph, it crashes. Is there any workaround? |
@henisz I think the problem here is force atlas 2, not able to handle this. Can you open a separate issue? The workaround now would be not using force atlas 2 |
Tried multiple layouts. Similar errors. Which would you recommend?

@henisz I'm actually going to painfully approach this by having a script which generates multiple gexf files, each representing a window of time, without dynamic edges. Then we can apply the Force Atlas manually to each file. In my work, I need to produce modularity over time, and this doesn't work with dynamic weights either. So I guess this approach is best for my needs. |
I want to save a dynamic network in Gephi, to gexf file format, however even if I try to save the most simple dynamic network, gexf file abruptly ends in the midle of first edge definition :
<edge id="0" source="0" target="1"
I figured to make a small graph in Gephi, with 4 nodes:
One link:
And then the whole output from in the gexf file is:
Am I doing something wrong or is this a bug?
I would like to use Gephi for the analysis and visualization of dynamic networks, but for that I need to be able to save the dynamics into a file :) Any suggestions are welcome.
