<br>
Is the system metallic or does your calculation have a gap?<br>
<br>
The charges and magnetization values on different atoms are not
exactly the same so it seams that they are not in equivalent
positions. So they could have non equivalent pdos.<br>
Have you examined pdos of individual atoms ? <br>
<br>
The total magnetization comes from the partially filled 4f
electrons of Ce.<br>
If the system has a gap then exactly one f-related band would be
fully occupied in the up and dw bands and the total magnetization
would be 0 even if the individual atoms are not <br>
equivalent. If there is no gap a complete compensation between up
and dw states is more strange.<br>

<div>In the input file I am trying the AFM configuration:</div>

<div>
<div> nspin = 2</div>
<div> starting_magnetization(1) = 1.0</div>
<div> starting_magnetization(2) = -1.0</div>
</div>
<div><br>
</div>
<div>where species 1 and 2 are Ce atoms (Ce1 and Ce2). </div>
<div><br>
</div>
<div>As the total_magnetization is equal to zero, I was
expecting to obtain pdos-up = pdos-down. I don't understand
what I am doing wrong. I really appreciate any help you can
provide.</div>

A run time check has been added on the SVN version as of

Are you using twfcollect option or are you sure you are
using the same parallel configuration<br>
in the pw.x and in the pp.x calculation ?<br>
