The specific error message generated when I try to use a layout is

java.lang.IllegalStateException: The weight is dynamic, call getWeight(timestamp) or getWeight(interval) instead

I reformatted all of my files per the example above and while they import correctly as soon as I try to graph them dynamically, GEPHI hangs. The only workaround that I can find is to ignore the non-binary dynamic edge weights (i.e., do NOT convert column weight to dynamic before importing in which case edge weights do vary by time but only switching from 0 to 1 based on the time intervals in timeset). If I do this, I can see the dynamic graphs but obviously lose a lot of information. As soon as I present weight to be dynamic prior to importing, while the data imports correctly with weights >1, GEPHI repeatedly hangs as soon as I visualize the graph. Any advice on this problem would be most welcome.

Thank you for your quick reply. I have made this change and it works seamlessly.

Hi,
Currently you will need to name your 'Timestamp' column 'timeset' instead. This is a limitation that will be improved.

Importing *.csv edge list with dynamic weights

Am unable to import a *.csv file with dynamic weights for some observations. Can anyone help me correctly format the sample file below. Have spent a good part of a day trying various permutations. Thanks to any and all, Vit
