Help - Old:Main menu (until 2.0.23)

This article describes this feature for TreeGraph 2.0.23 or (not necessaryly all) earlier versions. See here for the article on the latest version and a list on other available article versions.

The main menu is the major way to access all functions of TreeGraph 2. (Note that most functions can also be accessed by the tool bar, the context menu or a keyboard shortcut.)

An option followed by "..." means that a dialog will be displayed which asks you for further parameters for this function (e.g. Save as...). Other options do not need further parameters (e.g. Select all).

File menu

The file menu contains all options related to opening and saving of tree files and graphic files.

Option:	Function:
New	Creates a new (unsaved) tree document and opens it in the editor.
Open...	Displays a dialog to open a tree file. This option can either be used to open a TreeGraph 2-document (*.xtg) or to import a document in another tree format (e.g. Nexus). (See Open files for details.)
Save	Saves the tree file which is currently focused. If this file has just been created you will be asked to specify a file name (same as Save as..).
Save as...	Displays a dialog to save the tree file which is currently focused at a new position.
Close	Saves the tree file which is currently focused. If that file is unsaved you will be asked whether to save recent changes.
Export to graphic/PDF...	Allows you to export the tree in the currently focused file to a graphic file or a PDF. (See Exporting trees as graphics for details.)
Export to Newick/Nexus...	Allows you to export the tree in the currently focused file to a Newick or Nexus tree file. (See Exporting trees as Newick/Nexus files for details.)
Add support values...	Allows you to import additional node/branch data (e.g. support values) from another tree file into the currently focused tree. (See Adding support values for details.)
Exit	Terminates TreeGraph 2. (You will be asked whether to save open tree files.)

Select menu

The options of this menu allow you to select different parts of the currently focused tree. All options can be combined, i.e. all elements selected by an option of this menu are added to previous selection. (See Selecting elements for details on the options describes here.)

Option:	Function:
Select all	Selects all elements in the tree (including all legends and the scale bar if present).
Select subtree(s)	Selects all elements in the subtree(s) under the currently selected elements (not including any legends).
Search text...	Selects all text elements which contain a certain text. (See Search text for details. This option is also contained in the Edit menu.)
Select this type(s) in document	Selects all elements in the whole document which have the same type as the currently selected elements.
Select this type(s) in subtree(s)	Selects all elements in the subtree(s) under the previously selected elements which have the same type as the respective selected root elements.
Select leafs in document	Selects all leaf-nodes of the tree.
Select leafs in subtree(s)	Selects all leaf-nodes that are contained in one of the subtrees under the currently selected elements.
Select labels with this ID	Selects all labels that have the same ID as one of the currently selected labels.
Select labels in subtree(s)	Selects all labels that are contained in one of the subtrees under the currently selected elements.
Select all legends	Selects all legends in the document.
Select legends with the same position index	Selects only such legends that have the same position index as the currently selected legend(s). (See the Legend article to find out what the position index is.)

Edit menu

This menu contains all options that manipulate the structure of a TreeGraph document like adding, deleting, moving document elements or changing the contents of any node/branch data.

Undo/Redo

Option:	Function:
Undo	Lists the last operations that have been performed on this document and allows you to undo them. (The selected operation and all operations that were performed afterwards are undone.)
Redo	Lists the last operations that have been undone and allows you to redo them. (The selected operation and all operations that were performed before are redone.)

Insert/ copy/ delete

Option:	Function:
Copy	Copies the currently selected element to the clipboard. (See Copying/cutting document elements for details.)

Paste	Inserts the content of the clipboard at the selected position. (See Copying/cutting document elements, Inserting nodes or Inserting legends for details.)
Delete	Removes the currently selected elements including their subtrees. (See Deleting document elements for details. Use Collapse node if you want to remove a node without deleting its subtree.)

Add elements

Option:	Function:
New node	Inserts a new node at the selected position. (See Inserting nodes for details.)
New text label...	Adds a new text label to the currently selected branch.
New legend	Inserts a new legend into the document which is anchored at the currently selected node(s). (See Anchoring legends for details.)

Changing the global tree structure

Option:	Function:
Move subtree up	Moves the currently selected node (including its subtree) upwards. (See Moving nodes for details.)
Move subtree down	Moves the currently selected node (including its subtree) downwards. (See Moving nodes for details.)
Ladderize up	Sorts all nodes in the subtree of the currently selected node by the number of leafs contained in their subtrees. (See Ladderizing for details.)
Ladderize down	Sorts all nodes in the subtree of the currently selected node by the number of leafs contained in their subtrees. (See Ladderizing for details.)
Root here	Reroots the tree at the currently selected position. (See Rerooting for details.)

Changing the local tree structure

Delete subelements	Deletes all subtrees under the currently selected node so that the selected node becomes a leaf.(See Deleting subelements for details.)
Collapse node	Deletes the currently selected node and adds all its child nodes to its parent node. (See Collapsing nodes for details.)
Separate branch	Separates the currently selected branch into to branches which are separated by a new node. (See Separating branches for details.)

Changing text and ID elements

Option:	Function:
Edit text...	Displays a dialog to edit the text of the currently selected text element. (See Editing text element values for details.)
Change branch length...	Displays a dialog to change the branch length of the currently selected branch. Here you can also define if a branch length shall be stored at all. (See Changing branch lengths for details.)

Tile horizontal	Arranges all windows in columns. Windows are usually wider than high. (See example below.)
Cascade	Arranges all windows on top of each other. (See example below.)

Window arrangements

Tile vertical: This option is useful to display two trees with many taxa next to each other.
Tile horizontal: This option is useful to display two trees with long branches below to each other.
Cascade: This option is useful to directly select window with the mouse, if many documents are opened.
