What does the coloring of “nodes” in network images mean?
Each PubGene networks is drawn in response to a specific query. The color scheme in the networks reflects “distance” from the query term submitted. If a single gene term is the query its “node” in the network will be colored bright red. Neighbors of (genes co-cited with) the query gene are a darker red color and neighbors of neighbors are colored black. If two genes are submitted in the same query, both will be shown as bright red in the network. Keyword queries using default settings will draw networks with as many as 10 of the nodes in the network colored bright red, these corresponding to the 10 genes most significantly associated with the keyword.
