node size relative to number if adges

[jean simon]

Hello,


I am using cytoscape 3.4.  I want to correlate node size to the amount of edges linked to the gene ( to highlight hub molecule). There are some tutorial for previous version of cytoscape but the options  are different in the new version. could you please help me with that?

 Thanks
J

Hi J,
what you want for your visual mapping is the node degree (number of edges) as an attribute on your nodes.
You can get this via the NetworkAnalyzer

Tools -> NetworkAnalyzer -> NetworkAnalysis -> Analyze Network

Depending if you want to have degree, or in-degree/out-degree select directed or indirected.

Now you can use 'Degree' attribute in a VisualMapping to node size
ControlPanel -> Style -> Node -> Size

Select Column=Degree and ContinousMapping and adapt the mapping function, i.e. how the node degree maps to size.
