</span>Dear Ryky,<br>
it is possible to generate norm-conserving PAW, by setting the norm-conserving<br>
(or augmentation) radius equal to the pseudization radius in the input of<br>
ld1.x, however, there is a little bug (feature?) in ld1.x that prevents it<br>
from working.<br>
<br>
So, first of all you have to change atomic/src/gener_pseudo.f90 at line<br>
252 you change<br>
IF ((which_augfun=='PSQ'.AND.ik(n<wbr>s)/=ikus(ns)).OR.&<br>
(lpaw.AND..NOT.lnc2paw)) THEN<br>
to<br>
IF ((which_augfun=='PSQ'.AND.ik(n<wbr>s)/=ikus(ns))) THEN<br>
<br>
and recompile ld1.x<br>
<br>
Here is an example starting from the input of this file <<a href="http://www.quantum-espresso.org/wp-content/uploads/upf_files/Si.pbe-n-kjpaw_psl.0.1.UPF" rel="noreferrer" target="_blank">http://www.quantum-espresso.o<wbr>rg/wp-content/uploads/upf_file<wbr>s/Si.pbe-n-kjpaw_psl.0.1.UPF</a>>, it seems<br>
to work but I did not test it for real:<br>
