## OCCURRENCE

### ARB_NT/Tree/Beautify tree/...

## DESCRIPTION

### Arranges branches and groups according to the size of each subtree. If the size doesn't differ at a furcation, subtrees will be sorted alphabethically. This ensures the sorting is stable.

### Sorting does not change the tree topology, it only swaps branches!

## Available sort modes

### The first sort mode sorts the bigger branches to the top, the third sorts them to the bottom.

### The second sort mode sorts the bigger branches to the edges of the tree and the smaller branches to the center.

### The fourth and fifth mode are designed to sort the tree for the radial tree display mode.

### The fourth mode does the opposite of the second mode: it sorts bigger branches to the center and smaller ones to the borders of the tree.

### The fifth mode alternates between second and fourth mode.

## NOTES

### This facilitates the comparison of tree topologies resulting from different treeing approaches.

### See also ´Sort tree by other tree´.
