JContextExplorer: a tree-based approach to facilitate cross-species genomic context comparison.

abstract：BACKGROUND:With the growing availability of full-text articles online, scientists and other consumers of the life sciences literature now have the ability to go beyond searching bibliographic records (title, abstract, metadata) to directly access full-text content. Motivated by this emerging trend, I posed the followin...
