-FuncTree is a web application that allows user to map omics data onto a pre-defined radial tree (e.g. based on the [KEGG brite functional hierarchy](http://www.genome.jp/kegg-bin/get_htext?br08902.keg)) to help them to quickly and comprehensively understand the functional potential of their data, and to develop further hypothesis and scientific insights.
