Trees section

The Trees section of the Explorer panel is used to control which phylogenetic tree is displayed in the Tree view, and allows you to create additional trees or delete them.

*Note: If you are instead seeking information on the Tree section of the Style panel, click here.

To open the Trees section, click on the Explorer tab (); if the Trees section is closed, expand it by clicking the Trees bar. Alternatively, choose View > Explorer > Explorer or View > Reset Panel Layout.

Prior to performing a multiple alignment, the Trees section is empty. Once an alignment has taken place, the Trees section contains a table with one row for each phylogenetic tree that has been generated. The table contains three columns:

• Name – The default tree generated during multiple alignment is always named Tree. Other trees are assigned names during the use of the Tree > Compute Phylogeny command.

• Method – The algorithm used to generate the tree.

• Status/Completion – Time used to generate the tree.

To the right of the table are two tools:

Icon	Name	Purpose
	Computes a new phylogeny for the aligned sequences	To create a new tree and add it to the table. This is a shortcut to the Tree > Compute Phylogeny command. See the topic Phylogenetic Trees for instructions on adding a tree.
	Remove phylogeny	To delete a selected tree from the list.
