You can, however, examine these attributes in Cytoscape, using Cytoscape’s the Data Panel to display data values associated with selected nodes immediately below the Cytoscape window.ĥ.2 Modifying the display: defaults and mappings Such a change requires that you specify and apply visual style mappings, which will be explained in the next section. Note that adding the attributes does not in itself cause the appearance of the graph to change. ![]() StringsAsFactors = FALSE) # important when loading strings! df <- ame (moleculeType=c('kinase','TF','cytokine','cytokine'), Check out the other vignettes for more exampls. However, you can also include attributes together with the original graph models as Bioconductor graphs, igraphs or ames and then use the provided create functions to create and load in a single step (see createNetworkFromGraph, createNetworkFromIgraph and createNetworkFromDataFrames functions). We continue with the simple 4-node graph, adding two kinds data values ( moleculeType' andlog2fc’). One of the core features of Cytoscape is visual styles, which allow you to specify how data values (e.g., kinase',transcription factor’ expression ratios) should be conveyed in the visual properties of the graph (e.g., node shape, node color or size). ![]() For instance, we may know that protein A phosphorylates protein B, that A is a kinase and B a transcription factor, and that their mRNA expression (compared to a control) is a log2 fold change of 1.8 and 3.2 respectively. By conveying this information visually, the graph will be easier to explore. We often know quite a lot about the nodes and edges in our graphs.
