Gephi forums

Yes, that was it. All working now - thanks so much! Final question: I don't really want to use a time interval, I would rather use a 'first seen' datetime. In the example below I achieve this by converting first seen datetime to unix timestamp and then add a big time offset to make sure the node sta...

Is it because when I try to import the 'edge table' it is not recognising the 'source' and 'target' as node ids because they are strings? They are unique strings (representing an IP address) but is the edge table expecting an integer? Here is the first two lines of the CSV file: 'source','target','w...

Hi, Well the import of the CSV file for the node table worked just fine. I did 'import spreadsheet' and selected 'node table' set the data times and it all worked. I have a node table with all of my data, and with 'node id' added. Problem is that I can't see how to add the 'edge' table as per your l...

Excellent, thanks for the quick reply. I will try that today and report back.
Cheers

Hi Guys, A while back you helped me get my netflow data working on Gephi, with weights. As a reminder I ended up using DL format : <src_ip>, <dst_ip>, <number of packets> This all works beautifully :-) Now I would like to add time to the picture. In netflow there is a start_time and an end_time for ...

Is this the answer:

Use the edgelist1 format for a DL file.

eg;
dl
format=edgelist1
n=3
data:
1 2 12
1 3 12
1 4 256
2 3 64
1 2 12
1 2 12
1 2 12

When there are parallel edges will it add the weights together?

Hi I have used Gephi for a while and love it for visualisation of some security logs - in this case netflow. Today I use simple src<->dst IP address pairs and it works very well. However I want to try something else and I quickly shows how little I understand this area! Example: 1,2 1,3 1,4 2,3 1,2 ...

Still very n00b questions here, and I apologise. I have run test sample of data and get a simple visualisation that is based on srcIP<->dstIP. The clustering is based on the number of connections (or edges or actually 'flows' ) This is ok, but I would like to weight the graph on packets, and then on...

Hi I am new to Gephi (and data visualisation at this level) and I would like to experiment at looking at netflow data on Gephi. The netflow data is roughly in the form: datetime srcIP srcPort dstIP dstPort octets packets Can someone guide me on how I process the data to try some visualisation? Initi...

I am starting out with Gephi and wanted to just check my config before I move to some big graphs. Java is all set for 64-bit I think: java -version java version "1.6.0_22" Java(TM) SE Runtime Environment (build 1.6.0_22-b04-307-10M3261) Java HotSpot(TM) 64-Bit Server VM (build 17.1-b03-307, mixed mo...
