editing node ID

[Janet Higgins (JIC)]

I have added some new nodes to a network and I would like to name the nodes with the AGI code for the gene so I can merge with other networks, however I cannot find how to change the node ID. I have done this before but I cannot see how to do it now.

Can anyone help?
Thanks

You can't change Node IDs. What you can do is add an attribute value to the node which can then be displayed by the vizmapper. A commonly used attribute of node labels is SEMANTICS.CANONICAL_NAME. Several of the visual styles will display this attribute as the label for a node. To set a node's (n1) label you could do something like:

Cytoscape.getNodeAttributes().setAttribute(n1.getIdentifier(),SEMANTICS.CANONICAL_NAME, "my new label");

Indeed, you can not change the Node ID from within the application via the
user interface. You can, however, change the ID programmatically:

Cytoscape.getCyNode("old_id", false).setIdentifier("new_id");

I suspect you are not programming, though, and want a way to do this as a
user. Here is one workaround:

Go to the "Editor" tab in the left panel and then double-click in the
network window. You can now type any ID you want, press enter, and a node
will be created with that ID.
