## OCCURRENCE

### ARB_NT/Species/Mark species/...

## DESCRIPTION

### Provides several ways to mark species.

### Three general methods are available:

- mark
- unmark
- invert

### Each of these methods can be applied to one of three basic sets, namely

- all species in the database
- all species in the current tree or
- all species NOT in the current tree

### These three sets can be intersected with one of the more specific sets, which are provided by the submenu entries at the bottom of the 'Mark species' menu, namely

- all complete species (see ´Partial sequences´),
- all partial species or
- all species with data in the current alignment.

## NOTES

### To check the number of marked species

- look at the button in the ARB_NT top area displaying the number of marked species or
- choose 'Count Marked Species' from the 'Mark species' menu.

### The "current tree" is the tree currently displayed in the main window. When you have multiple ARB_NT windows open (see ´Multiple ARB_NT windows´), make sure you use the menu of the intended ARB_NT window.

### When using one or two sets (tree, complete, partial or alignment), all species not included in the set (or in both sets) will not be affected.
