TreeDyn ?

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 tree's 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.

    Update TreeDyn to patch 198 by using the "TreeDyn Update" option from the "Help menu". The latest version always include all the previous ones. If the patching process is stopped while downloading, please reload/install the treedynpack (this bug is now fixed).

    Download TreeDynPack (198.3)
    Linux (.tar.gz file)
    unzip/untar treedynpack.tar.gz. Go to the treedynpack folder and then use the command "./treedyn". You may have to "chmod" treedynpack
    MacOSX (.DMG file)
    after decompression of the DMG file, double-clic on the TreeDyn icon. Copy the disk image file to your application folder or your Home directory
    Windows (.zip file)
    unzip under "C:\". if you have unzip under C:\ double click on the treedyn alias. If the has been unzip elsewhere, update the treedyn alias properties. For instance, if you unzip treedynpack under "C:\tree", edit the properties of "C:\tree\treedynpack\treedyn.lnk", then update the "target" entry to "C:\tree\treedynpack\+\treedyn.exe data" and update the "starting" entry to "C:\tree\treedynpack\+". Also, you can update the alias icon using the file ~\treedynpack\+\+\icon\itd.ico file
