A set of these encoded or mapped table data sets is called a Style and can be created or edited in the Style panel of the Control Panel. In this interface, the appearance of your network is easily customized. For example, you can:. Set node sizes based on the degree of connectivity of the nodes. You can visually see the hub of a network…. Cytoscape 3 has several sample styles.
Below are a few examples of these applied to the galFiltered. The Style interface is located under the Style panel of the Control Panel.
The panel displays the mapping details for a given style and is used to edit these details as well. The Cytoscape distribution includes several predefined styles to get you started. To examine a few styles, try out the following example:.
You can change the style by making a selection from the Current Style drop-down list, found at the top of the Style panel. For example, if you select Sample1 , a new style will be applied to your network, and you will see a white background and round blue nodes. Additional sample styles are available in the sampleStyles. Cytoscape allows a wide variety of properties to be controlled. These are summarized in the tables below.
For each property, you can specify a default value or define a dynamic mapping. Cytoscape currently supports three different types of mappings:. Continuous data are mapped to properties. Depending on the property, there are three kinds of continuous mapping:. Continuous-to-Continuous Mapping : for example, you can map a continuous numerical value to node size.
Color Gradient Mapping : This is a special case of continuous-to-continuous mapping. Continuous numerical values are mapped to a color gradient.
Continuous-to-Discrete Mapping : for example, all values below 0 are mapped to square nodes, and all values above 0 are mapped to circular nodes. However, note that there is no way to smoothly morph between circular nodes and square nodes. In Cytoscape 2. The following value types are supported:. Cytoscape allows you to set custom graphics to nodes. Cytoscape provides a set of images and you can also add your own images in the Image Manager , as well as remove or modify existing ones.
Node graphics are used and defined like any other property, through the Style interface. In general, saving and loading images is automatic. When you quit Cytoscape, all of the images in the Image Manager will be saved automatically. There are two types of saving:. In any case, images will be saved automatically to your system or session and will be restored when you restart Cytoscape or load a session.
The following tutorials demonstrate some of the basic Style features. Each tutorial is independent of the others. Once the result is displayed, simply close the window. All statistics are stored as regular table data. Enter a name for your new style when prompted.
Since no mappings are set up yet, only default values are defined for some of the properties. Change the default node color and shape: To set the default node shape to triangles, click the Default Value column for the Shape property.
A list of available node shapes will be shown. Select the Triangle item and click the Apply button. You can edit other default values in the same way. In the example shown below, the node shape is set to Round Rectangle , while Fill Color is set to white.
The new Style is automatically applied to the current network, as shown below. Now you have a network with a new Style. The following section demonstrates how to create a new style that has a discrete mapping. The goal is to draw protein-DNA interactions as dashed lines, and protein-protein interactions as solid lines.
Choose a data column to map to: Expand the entry for Stroke Color Unselected by clicking the arrow icon on the right. On the right side of the cell, click on the … button that appears. A popup window will appear; select green or similar, and the change will immediately appear on the network window.
A sample screenshot is provided below. At this point, you have a network with some edge mappings. The following section demonstrates how to create a new style using a continuous mapping. The goal is to superimpose node statistics in this example, node degree onto a network and display it along a color gradient. Set the node table column: Expand the entry for Fill Color by clicking the arrow icon on the right.
This automatically creates a default mapping. Define a color palette. We encourage you to choose palette from the existing ones provided, but you can also choose the color states yourself and provide any number of intermediate colors.
Both methods are described here. Choose a predefined palette from the Palette picker. These come from published recommendations for choosing colors in scientific and cartographic applications, such as BrewerColors.
Click the Current Palette button in the top left of the Continuous Mapping Editor to choose from a set of palettes. Below shows the Set Palette dialog to choose a full palette. Define the points where colors will change: Double-click on the black-and-white gradient rectangle next to Current Mapping to open the Continuous Mapping Editor.
Note the two smaller triangles at the top of the gradient. Define the colors between points: Double-click on the larger leftmost triangle facing left and a color palette will appear. Set the color white and repeat for the smaller left-side triangle. For the triangle on the right, set the color green and then choose the same color for the smaller right-side triangle. The color gradients will immediately appear on the network. Repeat for other properties: You can create more continuous mappings for other numeric table data.
Switch the Current Style to Minimal. Now your network looks like the following:. Create a discrete mapping for Fill Color. Cytoscape will automatically generate different colors for all the property values as shown below:. Create a discrete mapping for Label Font Size. Type 3 for the first value and click OK. Enter 3 for increment. The final view is shown below:. This mapping generator utility is useful for categorical data.
The following example shows a discrete mapping that maps the species column to node color. This tutorial is a quick introduction to the node image feature. You can assign up to nine images per node as a part of a Style. In this first example, we will use the presets that Cytoscape 3 has. In general, you can use any type of bitmap graphics. User images should be added to the Image Manager before using them in a Style.
If you are continuing from the previous tutorials, skip to the next step. This creates several new table columns statistics for nodes and edges. Click the Style panel in the Control Panel , and select the Solid style. Click the Default Value cell of node Transparency and set the value to zero. Set the Default Value of node Size to Also change the edge Width to 6. Drag and Drop this icon to the image list which automatically adds it to the manager.
In the Continuos Mapping Editor , add a handle position by clicking in the Add button, and move the handle to 0. Double-click the region over 0. Click its Default Value cell to move the position of the graphics to upper left.
Now the important nodes in the network nodes with high betweenness centrality are annotated with the icon:. The goal of this tutorial is to learn how to create and customize node charts from data stored in the Node tables.
Cytoscape User Manual stable. Introduction 2. Launching Cytoscape 3. Command Line Arguments 4.
Dash Cytoscape is a graph visualization component for creating easily customizable, high-performance, interactive, and web-based networks. It extends and renders Cytoscape. Dash Cytoscape graphs are interactive! Scroll to zoom and drag on the canvas to move the entire graph around. You can move nodes by dragging it, or by clicking, holding, and moving your mouse to the desired location and click again to release.
