[Pw_forum] Calculating g-tensor using gipaw

[Aurab]

Dear Apsi,
Thank you for the reply. I checked my pseudopotential files and yes you are
right! The core radii cutoff has been read zero! Is it just a bug in the
ld1.x code or there is particular reason behind. I can't think of any.
Thanks a ton,
Aurab
