To get started, click on the Style tab in the control panel, and make sure the Node tab is selected at the bottom of that pane. Now that Cytoscape knows which nodes are which, we can color the nodes based on whether they’re an actor or a film. That’s good! It means the last step worked! Use node attributes to color nodes (1) Not a lot, at first glance! But if you look at the pane at the bottom of Cytoscape’s window and click on the Node Table tab, you’ll see that your node table now has an extra column, in which each entity is labeled as either an actor or a film. That means that Cytoscape has interpreted that column, correctly, as attribute information for your nodes. You can see that Cytoscape has labled your type column with an icon that looks like a document. The column labeled with a key is the column Cytoscape will use to try and match your node attributes with the nodes that already exist in your Cytoscape graph. Hopefully, the window that pops up looks something like the one below. Check to make sure Cytoscape interpreted your data properly In the window that pops up, select your node list and click Open. We’re now going to add our new node list to the existing graph.ĭo that by clicking on the Import Table from File button, circled below. Head back to Cytoscape, where the graph you created during the previous tutorial should be open. Add your node list to your Cytoscape graph

If you have an edge list but no node list, here is how to convert an edge list into a node list.įor this tutorial, please use this node list. You could provide multiple columns, though, like gender or director. I’ll just supply one here, called type, containing either actor or film. In subsequent columns, you can provide attributes for each of your nodes. Actors and films should all be in the same column.īy convention, we usually label node names id, although it won’t mess anything up if you want to label the column something else. We only want Ida Anderson to appear once, and we only want each film’s title to appear once. We don’t want this in our node list, though. For example, since Ida Anderson appeared in multiple films, I had rows that looked like this: actor My edge list, as you may have noticed, contained many actors’ names and film titles multiple times. Your node list should contain, at a minimum, one column that supplies the name of every node once. We’ll just deal with node attributes here, but the same steps apply to edge attributes, too.) Preparing a node list For example, if I had a People column and a Book column, I could use edge attributes to describe the nature of each connection: published, wrote, illustrated. In the case of edges, the attributes usually describe the nature of the connection between nodes. (Actually, edges can have attributes, too, as you might have guessed. That extra information about your nodes is called attributes. That way, you can feed Cytoscape extra information that you can use to distinguish among nodes. But you might also want to supply Cytoscape with a list of nodes. Īs we learned in the last tutorial, all Cytoscape really needs is an edge list with two columns in it.
