Gliederung
Text
Network models form a simple and flexible way of representing diverse associations within complex systems, and its applications are well-established in a wide range of fields in biology [1], [2], [3]. Within a common bioinformatics workflow data integration, network analysis and visualization accompany each other [4], [5], and comprise fundamental challenges of combining various tools. Implementation of fully automated pipelines enhances the intricacy of such tasks furthermore [6].
Using standard technologies, we demonstrate a course from data acquisition to the finished visualization, and options to achieve the individual sub tasks. Thereby the network data exchange (NDEx) platform [7], [8] and the Cytoscape project [9], and appendant R [10], form the core components.
We use our R package ndexr [11] to retrieve networks from the public NDEx platform, and also to store the results for later collaboration and publication. Cytoscape is one of the most popular open-source software tools for the visual exploration of biomedical networks. Beside the graphical interface, the latest release offers a RESTful interface [12], [13] and R packages [14], [15] providing access to it.
Along an exemplary bioinformatics workflow, we demonstrate how the single steps can be performed not only interactively, but also in a fully automated manner. Each step can be done using Cytoscape or R, or a combination of both: Controlling Cytoscape remotely from within R. Starting at an interactive analysis we move towards automation, illustrating the interchangeability and flexibility of the different approaches.
