TreeDyn is a powerful tree visualization tool. Many powerful tree editors are now available, but existing tree visualisation tools make little use of meta-information related to the entities under study such as taxonomic descriptions, geographic distribution or gene functions.

This meta-information is useful for the analyses of trees and their publications, but can hardly be encoded within the tree itself (the so-called newick format). Consequently, a tedious manual analysis and post-processing of the trees images is required. Particularly with large trees, multiple trees and multiple meta-information variables.

TreeDyn links unique leaf labels to lists of variables/values pairs of annotations (meta-information), independently of the tree topologies, remaining fully compatible with the basic newick format. These relationships are used by dynamic graphics operators, information visualization methods like Projection, Localization, Labelization, Reflection allowing an interaction from annotations to trees, from trees to annotations and from trees to trees through annotations. Get TreeDyn and take it for a spin to see what it can actually do for you.
