The table is organized neither with purpose to compare nor in manner adequate for the scope of an absolute evaluation. All tools display different interactivity and tree manipulation functionalities making each one suitable to alternative case studies. In addition, generic use, i.e. not only phylogenetic related, may apply, an issue that depends on the content of the data incorporated by a user in the acceptable per tool input file formats and tree management possibilities.
