Navigator2.0 is the Protein Protein Interaction Networks Visualization Tool. Navigator can visualize relationships among tens of thousands of proteins as well as analyze various kind of information related to the network. By doing so, it can improve the ability to find out more meaningful interactions and proteins relevent to the protein of users' interests. However, it lacks of functionality that can visualize and vividly distinguish only those proteins of special interest. Our plugin would provide a better interface for the cluster analysis.
