TreeSnatcher Plus Description

TreeSnatcher Plus was developed to be a GUI-driven Java application that automates the generation of a machine- readable representation of multifurcating phylogenetic trees contained in pixel images. It uses image processing methods to prepare the image and to detect the tree structure. The user supervises the semi-automatic recognition process and makes corrections to the image and to the topology where necessary. At the end the program produces a Newick tree code that represents the tree structure optionally including branch lengths. TreeSnatcher Plus is an extended and re-conceptualized version of TreeSnatcher. It is well fitted to support the research on complex phylogenies and will be helpful if one wants to combine phylogenies based on a collection of already published trees that are not electronically available. Moreover, TreeSnatcher Plus is also suited for educational purposes as it allows the user to construct his own trees and to modify existing topologies. Figures of phylogenetic trees are widely used in publications to illustrate the result of an evolutionary analysis. However, as one cannot effortlessly extract a machine-readable representation, i.e. a Newick expression, of the phylogeny from such images, those are not suited for subsequent reanalysis or easy compilation of tree topologies. Therefore a computer readable representation of a published tree has either to be built completely by hand or by using special applications. Here, TreeSnatcher Plus can be valuable. It identifies the topology of a tree (e.g. a figure from a publication) with user interaction. The application features a sophisticated graphical user interface that is based on the JAVA Swing API. The new version, TreeSnatcher Plus, has been developed from scratch and offers a stable graphical user interface, uses improved methods for image processing and for the analysis of the tree topology. In particular is it no longer necessary to preprocess an image before feeding it into TreeSnatcher Plus. The new application offers all the image preprocessing tools needed.
