The Tree Viewing Window
- When a tree has been calculated from an alignment, or imported via a - file or web service it is displayed by Jalview's tree viewing - window. Trees can be rearranged, used to select sequences and groups - in the associated alignment, saved in Newick format or exported as an - image or postscript file.

+Selecting Sequence Leaf Nodes
Selecting sequence ids at the leaves of the tree selects the
corresponding sequences in the original alignment. These selections
are also reflected in any other analysis windows associated with the
alignment, such as another tree viewer.
