DigitalTree: A Tool for Displaying Biological Data in Tree Structure

摘要

We developed a computational tool, DigitalTree, for displaying a two-dimensional weighted tree of biological data. Existing methods, Radial Layout, Hyperbolic Layout, Phyllotactic Placement, and Force-Directing were integrated into DigitalTree. DigitalTree preserves the distances between nodes in the tree and the trees topology. The tool has been applied in analyzing microarray data and phylogenetic trees.
