how to color positive and negative correlation in Cytoscape

Question

[Bioinfonext]

I have got four-column in Cytoscape input file having a source, target, and edge attributes, I want to show the positive and negative correlation (edge attributes) with different colors so do I need to add one more column for the type of correlation (positive, negative) to color these and then can I change the edge width based on correlation value?

       Source      Target                      cor              p
    Actinobaculum  Actinomyces   -0.083166733306677  0.557766591033679
    Actinobaculum  Chroflexi     -0.057666197516258  0.684693748325992
    graevenitzii     naeslundii  -0.057666197516258  0.684693748325992
    Actinobaculum  Actinomyces    0.082972778302491   0.558688695520664

Hi, this link to the Cytoscape manual might be helpful: Cytoscape Styles You can use your existing column and update the visual representation using the Edge properties tab in the Styles panel. Hope this helps. Thanks.
