How to depict edges as an indicator of no. of frames in which two residue interact in Residue interaction network using Cytoscape?

I am using RIP-MD tool to generate Residue interaction network from MD trajectories. the tool generates GML files which I load in Cytoscape. I want to visualise network in such a way that edge weight denotes the number of frames (percentage of total frames of MD trajectories) in which two residues interact. The edge weight may be denoted as thickness of edge or change of colour. I want edges to denote the number of times interaction between residue occurs in different frame of MD trajectories. Please let me know how can I achieve that?
