![]() Separately, each of these features provides useful new capabilities to Cytoscape. ![]() The second feature is the introduction of spreadsheet-like equations into Cytoscape's Attribute Browser to enable advanced transformation and combination of datasets directly within Cytoscape. The first feature allows non-programmers to map graphical images onto nodes, which greatly increases the power and flexibility with which integrated data can be visualized. Version 2.8 of Cytoscape has introduced two significant new features that improve its ability to integrate and visualize complex datasets. shape, color, size) as well as to perform complex network searches, filtering operations and other analysis. Attribute values can be used to control visual aspects of nodes and edges (e.g. Data are integrated with the network using attributes, which map nodes or edges to specific data values such as gene expression levels or protein functions. genes, proteins, cells, patients) represented as nodes and biological interactions represented as edges between nodes. Its central organizing principle is a network graph, with biological entities (e.g. Thus data integration, along with integrated visualization, is a key.Ĭytoscape, now in its eighth year of development, has become a standard tool for integrated analysis and visualization of biological networks ( Cline et al., 2007 Shannon et al., 2003). Although various datasets can appear quite different in quality and quantity, they all are reflections of the same underlying biological system and its responses. These network data extend and compliment a great deal of other information available in the biomedical sciences. Vast datasets are being gathered to delineate networks of various types and levels, including networks of genetic and protein–protein interaction networks of transcriptional and post-transcriptional regulation, social networks and multiscale networks that span several of these domains ( Fowler et al., 2009 Tan et al., 2007). Arguably, one of the most used environments is the statistical programming language The availability of high-throughput experimental data has led to the development of multiple computational methods to analyse these data.Networks are pervasive in biology. Furthermore,īioconductor 2 provides a comprehensive collection of packages to analyse biological data developed in Multiple R packages for computational biology and bioinformatics are available in various resources such as the Comprehensive R Archive Network (CRAN). ![]() It is an open-source project hosting 671 active and curated software packages as of September 2013.įor those not familiar with computational programming, learning These packages are subject to stringent quality control in terms of functionality and documentation. R and running packages can be a time consuming task and therefore the use of intuitive graphical interfaces can enhance the usability of the tool.Ĥ is a Java open-source framework with an intuitive graphical interface devoted to the visualization and analysis of networks.

Galaxy is an open-source web-platform to assemble workflows based on genomic experimental data analysis. Thus, Cyrface complements Taverna and Galaxy by enhancing GUIs for R within a different environment with complementary features.
