GROUP MODE

OCCURRENCE

ARB main window 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.

Collapsed groups are displayed as triangles (or rectangles in IRS tree; see ´SHOW IRS DENDROGRAM´).

The 'GROUP MODE' allows you to expand or collapse groups and to create, rename or destroy groups.

Click on the <GROUP> button of the ARB 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.

Collapse/expand:

To collapse a group, either click on the diamond shown at the root of the group, on the group bracket or its name.
To expand a group, click on the group triangle or its name.

Create a group:

Click on the root branch of the subtree which shall be grouped. Enter a group name when asked for.

Destroy / rename / keel-over groups:

Select group as described for 'collapse/expand' above, but use the right mouse button. Select the wanted action:
  • KeelOver: inverts the orientation of ´Keeled groups´
  • Rename: ask for new name and rename group
  • Destroy: destroys the groups

 

NOTES

The lengths of the triangle sides reflect the longest and shortest overall branch lengths within the subtree.

To collapse/expand via keyboard, see ´Tree display keyboard reference´.

When changing a keeled into a unkeeled group using KeelOver, that group is moved to its parents position. Use ´MOVE MODE´ to move the group information if that position isn't appropriate in your case.
