Color Nodes In Cytoscape Using An Attribute File?

Cytoscape is a powerful tool for the visualization and analysis of complex networks. The details presented in this section will apply only to. Refer to the section entitled [Network Visualization and Analysis utilizing Cytoscape 3. X] for documentation on using Cytoscape 3.

Prior to Cytoscape analysis, the Molecular Networking workflow must be completed. To perform molecular networking, follow the guide here. To download the output files, click mmanual.

For the remainder of this document, a sample dataset, molecular network and cytoscape output will be used. This document assumes Cytoscape has been downloaded, installed and opened.

Select the file within the networkedges folder. A new window will appear. To activate “Column 3” left-click cjtoscape the column name it will turn blue. Right-click and rename “Column 3” to “deltaMZ”. To activate “Column 5” left-click on the column name it will turn blue.

Right-click and rename “Column 5” to “Cosine”. Currently the preferred layout plugin is called FM3. To install this plugin refer to this documentation. A new window will open.

This window can be used to change the default values for the network’s nodes, edges and global settings such as background color. Now that a the basic network topology is visualized in Cytoscape, attributes containing metadata about each node or edge have to be imported.


There are a variety of attributes that can be imported into Cytoscape. To enable or disable an attribute column cyfoscape import, left click on the column.

If a column is checked and has black cyttoscape, it will be imported. If a column has an X and has gray manua, it will NOT be imported. Under Attribute Names, click the Transfer first line as attribute names box.

If you import attributes that you do not want to show in the Data Panel, they can be hidden. Click Select Attributes left most button in Data Panel. Uncheck any attribute you do not want to show. In this next section, suggestions for visualization of attributes within cytoscape are suggested.

While the use of some visualizations are strongly encouraged parent mass, cosine scoreother visualizations are up to the user. Users should explore how different Cytoscape settings change overall network visualization. Follow the manuual to visualize the attributes below. If the visualization does not appear in the network, click View and then Show Graphics Details.

In the dropdown list, choose parent mass default setting is ID. To visualize difference in cosine values between network pairs, the thickness of the edges is used. The thicker the edge line is, the higher the cosine score.

Edge line width is the y-axis and the cosine score in the x-axis. Adjust the empty red boxes to change the edge width thickness. Click OK to apply the settings. In this example, low cosine values have a edge line width approaching zero, while high cosine values have an edge line width approaching When the Molecular Networking workflow was performed for this example, the spectra were divided into two groups:.

In the dropdown list, choose DefaultGroups. This will color the network appropriately, with nodes corresponding to the crude sample G1 in red, nodes corresponding to standards G2 in blue, and nodes with spectra from both the crude sample and standard in green G1, G2.


To help aid in structural elucidation of nodes within a cluster, it may be helpful to know the mass difference between the nodes. After all attributes are correctly loaded, a cluster of related nodes should appear similar to this:.

If there are nodes of interest, users can highlight the node to view certain attributes of each node. The yellow nodes have been selected.

This will open a webpage as shown below. Further instructions on navigating the GNPS results can be found here. Page Operations V iew A ttachments 28 I nfo. X Visualization and Analysis Documentation.

X Analysis of Molecular Networks Cytoscape is a powerful tool for the visualization and analysis of complex networks. The downloaded data will be a zip file that contains several folders. For Cytoscape analysis, the following folders are of most interest: Describes the spectra – Used with data that included attribute mapping. Powered by Atlassian Confluence 3.

Network Topology File, describing similarity edges between spectra nodes – Each node has at least one neighbor connected by an edge. Network Topology File, describing similarity edges between spectra nodes – Allows individual nodes without neighbors to be 2.88. Describes the spectra – Used with data that did not include library search.

Describes the spectra – Used with data that included a library search. Corresponds to the cluster index in the molecular networking data within GNPS. Original data file and scan number of the node’s constituent cyoscape.

The default groups of the node’s spectra, comma separated. Mean retention time of the node’s constituent spectra.
