![]() Click the - select value - cell in the Column section, and select gal80Rexp in the drop-down.Find Fill Color in the list of Node properties and expand it to view the mapping options.Click on the Style tab in the Control Panel.Significance of expression values, gal80Rsig, will be mapped to Node Border Width nodes with significant changes will appear with a thicker border.The gal80Rexp expression values will be mapped to Node Fill Color nodes with low expression will be colored blue, nodes with high expression will be colored red.We can now use the data to manipulate the visual properties of the network by mapping specific data columns to visual style properties: To learn more about importing data, see the Importing Data From Tables. Similarly, you can select one or more rows in the Node Table, right-click on the selected rows and click Select nodes from selected rows to highlight the corresponding nodes in the network.Selecting nodes in the network (Shift + Click or Click-and-Drag) will update the Node Table to show only data for those nodes.The data used in this example is from yeast, and represents an experiment of perturbations of the genes Gal1, Gal4, and Gal80, which are all yeast transcription factors.įor this tutorial, the experimental data was part of the Cytoscape network file you loaded earlier, and is visible in the Node Table: Here, we will show an example of doing this. This creates a powerful visualization, portraying functional relation and experimental response at the same time. Probably the most common use of expression data in Cytoscape is to set the visual properties of the nodes (color, shape, border) in a network according to expression data. To learn more about importing networks from local files, see the Loading Networks Tutorial. The network will open with the default style, similar to the network on the right:.Click the Import network to Cytoscape (green arrow) button to the left of the network name. In the search results, find the galFiltered network with data.In the Network Search interface in the Control Panel, select NDEx from the drop-down, and type in "GAL1 GAL4 GAL80". We will use NDEx to find a relevant network.To get started, install and launch the latest version of Cytoscape.
