Construction, analysis, and visualization of dynamic networks in Cytoscape 3.0
DyNetViewer is a Cytoscape app to provide support for constructing, analyzing, and visualizing dynamic networks in Cytoscape 3. [Please downlaod the manual.](https://drive.google.com/open?id=0B2XsJM1bezIYb3NIQXZFT3JRYjA) You can also obtain some sample data files [here](https://drive.google.com/open?id=0B2XsJM1bezIYMDY5cHE4VUZjRWM). ###1. Introduction DyNetViewer is an OSGi bundle to provide support for constructing, analyzing, and visualizing dynamic networks in Cytoscape 3. Dynamic network can be constructed by integrating a static network with time-course data. For example, one can construct a dynamic protein interaction network by integrating time-course gene expression data. In DyNetViewer, four different methods were integrated to construct dynamic protein interaction networks (TC-PIN [1], NF-APIN [2], APIN [3],TS-PIN [4]) . One can construct a dynamic network by using the integrated methods or import a dynamic network directly. The constructed network or imported network can be displayed dynamically. DyNetViewer also provides node centrality analysis on a dynamic network. Twelve typical centrality measures including Betweeness Centrality (BC)[5,6], Closeness Centrality (CC) [7], Degree Centrality (DC)[8], Eigenvector Centrality (EC)[9], Local Average Connectivity-based method (LAC)[10], Network Centrality (NC)[11], Subgraph Centrality (SC)[12], Information Centrality (IC)[13],Stress, Radiality, Eccentricity, Centroid, were integrated in DyNetViewer. DyNetViewer supports calculation of multiple centralities simultaneously and plots the change chart of different centralities against time. DyNetViewer also integrates clustering algorithms (such as TSN-PCD[14]) for identifying and analyzing the clusters of dynamic networks. The clusters from dynamic network can also be viewed dynamically. This app is developed by Jie Yang, designed and directed by Dr. Min Li, from Central South University. ###2.Installation DyNetViewer is an OSGi bundle application of the revamped Cytoscape 3.0. • Download Cytoscape 3.4.0 beta.
