For any Node in the Cytoscape network diagram and for any Edge between Nodes, you can gather fresh evidence for the corresponding Edges from the scientific literature. There are two ways do this. The first way is to
This is illustrated in the figure below.
The second way to view literature references is to:
For either of these methods, a list of query terms (one for each selected Edge or one for each Edge adjacent to each selected Node) will be sent to Pubmed, up to 10 abstracts fetched for each query, and any associations among the Nodes impinging on the corresponding Edges will be attached as evidence on the respective Edge. By default the canonicalName attribute is used to identify the gene symbol.
You can select a different attribute by editing the preferences (via Edit->Preferences…), and changing the attribute name associated with the litSearchEvidenceAttributeName entry. If the attribute doesn't exist, you may create a new attribute. Please note that the attribute name is case sensitive.
