Indeed, the names were incorrectly switched. Whenever such a situation 
arises: it is the usersguide which is correct.

You will need less iterations before reaching convergence if you 
initialize the 'non-magnetic' atoms (e.g. Al) as -nm. It is not wrong, 
however, to initialize them as -up. It just takes more time.
