</span>Dear Phanikumar,<br>
the pseudopotential you are using for Cerium may or may not have the f<br>
electron in valence.<br>
<br>
If the electron is in valence you will have a corresponding file after the<br>
projwfc calculation. But your system will probably be metallica and have all<br>
sort of problems, unless you use DFT+U and know what you are doing.<br>
<br>
If it is in the core, you won't be able to compute its pdos (which anyway, is<br>
a delta function at the atomic state energy). Also your valence bands will<br>
miss some feature and probably be not completely correct.<br>
On the other hand, you will be able to get the calculation working without too<br>
much fiddling.<br>
