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 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.
- -- Clicking on an internal node of the tree will rearrange the tree - diagram, inverting the ordering of the branches at that node. -
-- Clicking anywhere along the extent of the tree (but not on a leaf or - internal node) defines a tree 'partition', by cutting every branch - of the tree spanning the depth where the mouse-click occured. Groups - are created containing sequences at the leaves of each connected - subtree. These groups are each given a different colour, which are - reflected in other windows in the same way as if the sequence ids - were selected, and can be edited in the same way as user defined - sequence groups. -
-Tree partitions are useful for comparing clusterings produced by -different methods and measures. They are also an effective way of -identifying specific patterns of conservation and mutation -corresponding to the overall phylogenetic structure, when combined -with the conservation -based colour scheme.
-File Menu
-This menu allows the displayed tree to be saved as a Newick tree -file (Save->Newick File), printed or exported as an image (PNG) or -Postscript file. -
-View Menu
-When the tree viewer is opened, it displays all the annotation -associated with a tree. Trees calculated by Jalview have branch -lengths, which correspond to the distance measure used to construct -the tree. Tree imported from outside may also contain bootstrap information, -or additional leaves from sequences not present in the associated -alignment. -
-The view menu contains options controlling the way a tree is -rendered and labelled:
--The tree layout will be scaled to fit in the display -window. You may need to reduce the font size to minimise the leaf -label overlap when this option is selected. -
-Brings up a dialog box to set the font size for the leaf -names. n is the current font size. -
-Labels each branch or leaf with its associated branch length. -
-Labels each branch or leaf with its associated bootstrap value. -
-Toggles the display of a '*' at the beginning of a leaf label to -indicate that there is no sequence corresponding to that leaf in the associated alignment. -
