Hi all

I am using cytoscape to evaluate the overlaps between multiple PPi networks.

After importing the networks from a txt file I used the "merge" tool using the "union" option to create the merged network. This part works well but ideally I would like to color differently each network and highlight the overlapping nodes with different colors/shapes, but I can't seem to find the way to do it. I tried to google the various "visualize/color overlapping nodes", someone suggested a plugin [here][1] but I can't find any indications that this was actually done.

Any suggestions/workarounds?

Thanks :)

<p>Create a mapping file in which you assign to each node the category it belongs to (i.e. network 1, network 2 or shared). Upload this file into cytoscape as a table using node names/IDs as keys. This will make another column in the node table associating the category as an extra node attribute. Then in the style tab, assign a color to each category using the discrete color mapping option of the node color.</p>
