In the filter dialog, you can build logical rules that take into account multiple columns in the table. Click the filter button above the network or go to the menu Apps → Omics Visualizer → Filter table. Omics Visualizer allows you to filter the rows in the table before visualizing them on a network. As no changes should be needed for this file, simply click OK to complete the import. The import dialog gives you the option to name the table, shows how the file is interpreted given the current settings, and allows you to change these as needed. Download and open the text file with the data described above. Go to the menu Apps → Omics Visualizer → Import table from file. Start Cytoscape or close the current session from the menu File → Close. An adapted and simplified table with the data from this study is available here. Each protein can have multiple significantly regulated phosphorylation sites, each of which is associated with two log-fold change values (one for each control tissue), a Benjamini–Hochberg adjusted p-value, and a cluster assignment that groups sites with similar behavior across samples. The study used mass spectrometry to compare the phosphoproteome of primary cells derived from epithelial ovarian cancer (EOC) to those of two healthy tissues, namely distal fallopian tube epithelium (FTE) and ovarian surface epithelium (OSE). We will work with phosphoproteomics data from an ovarian cancer study ( Francavilla et al., 2017). In this exercise, we will load a data table with proteomics data, filter it, retrieve a STRING network for the proteins, and visualize site-specific information onto the protein network. Similarly, make sure you have the stringApp, enhancedGraphics, and their dependencies installed before closing the App Manager.
#Conet cytoscape install
Search for the Omics Visualizer in the search field if it is not already installed, select it and press the Install button to install it. The exercises require you to have certain Cytoscape apps installed.
#Conet cytoscape update
Then start Cytoscape and go to Apps → App Manager to check for new apps, install them and update the current ones if necessarily. To follow the exercises, please make sure that you have the latest version of Cytoscape installed.
visualize site-specific data onto networks.In these exercises, we will use the Omics Visualizer app for Cytoscape to retrieve molecular networks from the STRING database and visualize site-specific information on the nodes.
