Dear Yaldaa,
I'm not sure I'm giving you the answer you wanted, yet this is what I can  
say:
pdos/dos output file are NOT scaled to bring the Fermi energy to zero.  
E.g. if you are using gnuplot and you want to have Ef=0 in the plot you  
can use a command like this:
  plot 'dos.dat' u ($1-Ef):2
wher Ef is (guess what?) the Fermi energy you can get from the output of  
the scf calculation.

The scale of energy (horizontal axes) is in eV.

regards
