Cytoscape是一个广泛应用于分子相互作用网络可视化的软件.发展了一个基于java的Cytoscape插件PNmerger.对于一个蛋白质相互作用网络,PNmerger能够使用KEGG数据库中的通路信息自动注释网络中的蛋白质.并通过网络和通路的比较发现网络中已知的通路元件,预测可能的通路元件及通路交联元件.该软件可以可视化网络中存在的通路模块,并将连接不同通路间的潜在交联元件显示出来.PNmerger软件能够有效地帮助实验人员发现网络中重要的功能线索,帮助实验人员进行实验设计.用户可以通过网站http://www.hupo.org.cn/PNmerger下载PNmerger插件.
PNmerger (a biological Pathway and protein Network merger) is a java based plugin for the widely used open source Cytoscape molecular interaction viewer. For a protein interaction network, PNmerger can automatically annotate the network proteins with the KEGG pathway information, fred the known pathway elements in protein network, and predict the possible pathway elements. To present the pathway information for the protein network, PNmerger illustrates the clusters of the nodes with the same biological pathway, and also presents the potential crosstalk elements between different pathways. This information will be helpful for the users to find the important clues for knowledge discovery and experimental design. PNmerger is available online at http://www.hupo.org. cn/PNmerger.
