[Pw_forum] Projected density of states

[Pingo Mutombo]

Dear PWSCF Users,

How can I compute the projected density of states for selected atoms of 
a given supercell? I can calculate the total DOS for a  Si(111)-7x7 
surface. However  I am unable to calculate the  projected density of 
states  probably because of the big size of the unit cell(249 atoms). At 
least I would like to calculate  the projected density  of states for 
selected Si atoms (adatom and rest atoms).
Best regards,
                                               Pingo
