I have two GR networks from which I extracted two subnetworks using the same list of genes (nodes). I want to be able to visually compare the topology of the resulting subnetworks. In other words, I want to be able to put the two subnetworks side by side and see which edges exist in one subnetwork but don't exist in the other.
So far, I have not been able to find a built-in functionality, nor a plugin, that would allow me to "freeze" a particular topology of nodes, and then add edges.
This is not a computational problem. I just want to be able to show a figure which will be easy to understand.
I could also calculate the union of edges in the two subnetworks and then color the resulting network's edges by "in subnetwork 1 only", "in subnetwork 2 only", and "common"; but I'd rather have a side by side figure.
Do any of you have any suggestions?
