### ARB_NT and ARB_PARSIMONY: <GROUP> button in the left column ### F3 on the keyboard
## DESCRIPTION
### A group is a subtree with a name assigned to its root node. The 'GROUP MODE' allows display of subtrees (groups of species) as triangles (radial tree) or rectangles (dendrogram). You also can convert a subtree into a group. ### Click on the <GROUP> button of the 'ARB_NT' window or the 'F3' key on the keyboard to activate the 'GROUP MODE'. In the latter case, the cursor has to be placed within the tree display area. ### Group species: Move the cursor to that internal node of the displayed tree (section) which defines the subtree and click on the left mouse button. The subtree-defining node is that located closest to the indicated root (open square) root of the whole tree which directly or indirectly connects all branches of the subtree. ### Ungroup species: Press the left mouse button while the cursor is over the triangle of a group. ### Transform a subtree into a group and assign a name to it: Proceed as described above using the right mouse button.
