yes, that seems to solve it.

CODE: 

<attributes class="edge" mode="dynamic">    <attribute id="weight" title="Weight" type="float"/></attributes>
And that makes your file work.

gephi is now recognising that the network is dynamic - this may have been fixed by changing the spell-syntax, but I still get the same error-message for both edges.

<spell start="9.9626" end="900010" />

This is my header (as you can see, mostly copy-pasted from the primer):

CODE: 

<?xml version="1.0" encoding="UTF8"?> <gexf xmlns="http://www.gexf.net/1.2draft" xmlns:xsi="http://www.w3.org/2001/XMLSchemainstance"xsi:schemaLocation="http://www.gexf.net/1.2drafthttp://www.gexf.net/1.2draft/gexf.xsd" version="1.2"> <meta lastmodifieddate="20090320"> <creator>Gephi.org</creator><description>A hello world! file</description><keywords>undefined</keywords> </meta> <graph mode="dynamic" timeformat="double" defaultedgetype="directed">
and this is an example of an edge:

CODE: 

<edge id="1" source="29" target="1"><attvalue for="weight" value="1.9216" start="9.9626"/><spells><spell> start="9.9626" end="900010" </spell></spells>  </edge>
however, when I load the file into gephi, I get
The time interval for edge 'edge id=1' attribute could not be parsed. Use xsd:date, xsd:dateTime or Double formatting.
when I try to copy-paste that message, I get "org.gephi.io.importer.api.Issue@20547840SEVERE", which I suppose is the identifier?

gephi reports the loaded file as not dynamic.

You can compress your GEXF file because Gephi handles ZIP and GZIP files.

Is there a more generic way of describing time, instead of dates? seconds really make more sense in my data, so if I could just give a float, that would be pretty helpful?

Would something like

<edge id="10" source="0" target="3">
<attvalue for="weight" value="1" start="0"/>
<attvalue for="weight" value="1.1" start="1"/>
<attvalue for="weight" value="1.2" start="2"/>
<attvalue for="weight" value="1.1" start="3"/>
<attvalue for="weight" value="1" start="4"/>

<spells>
<spell> start="1" end="2" </spell>
<spell> start="3" end="5" </spell>
</spells>

</edge>

work? Can I change the edge-weight like that?

I think I saw something in the primer about values overwriting each other quite easily, so that's why I'm only giving start-times.

Of course I'm going to write a matlab script that creates the gexf-file, but it is still a quality that the file doesn't become too large, so unnecessary text should be avoided. It's also a quality that gephi can handle the file easily. Under those constraints, does anyone have suggestions to best practice?

Thanks
