Dear PWscf forum members and developers,

in the future I would like to perform calculations on systems where 
relativistic effects 
are not negligible. Although I have generated USPP potentials using the code of 
Prof. David Vanderbilt's group, after browsing through the forum and checking 
out some 
subroutines of PWscf it became clear that potentials based on the 
Koelling-Harmon 
scalar relativistic wave equations are not suitable for this puorpose.
It seems to me that with the abovementioned code one can not generate 
fully-relativistic 
potentials based on the Dirac-Kohn-Sham equations (if I am wrong, please 
correct me). 

Now the issue is that by searching around I could not find fully-relativistic 
pseudopotentials 
with PBE functional for Bi, Hg, Se and Te. If possible, I would prefer to 
obtain fully-relativistic 
USPP potentials for these elements with semicore states treated as valence 
states, and 
with  Froyen-Louie-Cohen core correction. 
Is there somewhere a database where such potentials are available and I have 
overlooked 
it during my search?
If there are no such potentials widely available, can they be easily generated 
with the ld.x 
package developed by the group of Prof. Andrea Dal Corso or with other free 
tools?

I would like to thank you for any kind of contructive feedback.

Best regards,
Janos Kiss.
