<br>
I was doing a test calculation for CuO and got a message: <br>
" WARNING: atomic wfc # 6 for atom type 1 has zero norm<br>
WARNING: atomic wfc # 6 for atom type 2 has zero norm<br>
WARNING: atomic wfc # 2 for atom type 3 has zero norm<br>
WARNING: atomic wfc # 4 for atom type 3 has zero norm<br>
WARNING: atomic wfc # 5 for atom type 3 has zero norm<br>
<br>
The norm of the wfc is zero. Why does it happen? Does it depend on the
pseudo potential used? Can a gipaw pp be used with pw.x? (I download the pp from QE pps).<br>
<br>
Thank you very much in advance,<br>
