Comparison to other tree editors. I: Import, IE: Im- and export. ¹All programs tested with balanced binary trees in Newick format. The value listed is the number of terminals of the largest tree that could still be opened in less than two minutes on an average desktop computer (2.2 GHz AMD Athlon™ XP processor, 1 GB RAM). ²Numerical and textual annotations of nodes and branches can be calculated by any user defined mathematical expression from the values of other annotations in the tree. ³Any tree element can be copied to any position in the same or another tree (Programs that can only copy whole trees or paste subtrees to a new file are not checked in this column.). ⁴User defined text replacement in node names and all annotations. ⁵Numerical values of annotations define formatting of tree elements (e.g. color, width, text height). ⁶Documentation going beyond the original publication and explaining the different options. ⁷Only the last edit can be undone. (In contrast, TreeGraph 2 stores a whole undo history which can be undone (and redone) to any point.). ⁸Positioning options for the labels are not offered. ⁹Only one direction (not up and down). ¹⁰TreeDyn allows labeling a group of nodes with a legend (not automatically positioned), but the label gets lost during edit operations like ladderizing. ¹¹Specific formats for subtrees are possible. Branches and nodes cannot be formatted independently. ¹²Only very brief descriptions.
