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.
