Cytoscape is maintained by an active set of developers that oversee maintenance and upgrades of the core functionality. ↵ 4 Present address: University of California, San Diego, Department of Bioengineering, La Jolla, California 92093, USA. Cytoscape is a free, open-source, visual interface for importing, visually exploring, and analyzing graphical data 55. Thus, plug-ins also provide a general means of introducing and testing new features. Several of Cytoscape's core features (graph layout and node attribute mapping) ultimately led us to incorporate it into theĬytoscape Core platform. ↵ 7 Although attribute-based layout was initially implemented as a plug-in, its general applicability and tight integration with To accommodate new biological problems-is gained by not inscribing the notion of specific biological entities directly into Node attributes entitled “expression ratio” or “cellular compartment.” In this way, great freedom and flexibility-the ability For example, the core may represent a node (an abstract conceptįree of biological semantics) whose label is GCN4 (a text string with significance to yeast biologists as an important transcription factor) or we might use the Core to define Automated Installation via the Plugin Manager (available with Cytoscape 2.5 or later) Go to Plugins > Manage Plugins Go to Available for Install > Analysis and select MCODE. Of course, there is often substantialīiological significance associated with data in the Core. Once you have downloaded and installed Cytoscape and verified that it works, MCODE can be installed in two ways. Problem by leaving it to plug-in writers to adopt semantics adequate to the problem at hand. Were in the Cytoscape Core, we would be faced with a difficult question which semantics should we use? Cytoscape avoids this ↵ 6 Biological semantics vary widely within the biological community as well as fromproject to project. [The Cytoscape v1.1 Core runs on all major operating systems and is freely available for download from Interaction network for Halobacterium, and an interface to detailed stochastic/kinetic gene regulatory models. SeveralĬase studies of Cytoscape plug-ins are surveyed, including a search for interaction pathways correlating with changes in geneĮxpression, a study of protein complexes involved in cellular recovery to DNA damage, inference of a combined physical/functional The Core is extensible throughĪ straightforward plug-in architecture, allowing rapid development of additional computational analyses and features. Cytoscape's software Core providesīasic functionality to layout and query the network to visually integrate the network with expression profiles, phenotypes,Īnd other molecular states and to link the network to databases of functional annotations. The tool allows you to take a series of snapshots. Although applicable to any system of molecular componentsĪnd interactions, Cytoscape is most powerful when used in conjunction with large databases of protein-protein, protein-DNA,Īnd genetic interactions that are increasingly available for humans and model organisms. CyAnimator ( is a Cytoscape app that provides a tool for simple animations of Cytoscape networks. Cytoscape is an open source software project for integrating biomolecular interaction networks with high-throughput expressionĭata and other molecular states into a unified conceptual framework.
