Dear Min,

I reply to a old post concerning the generation of a pseudo potential for
sulfur. It seems to me that the main mistake is the number of electrons you
put in your pseudo especially on the 3p states. That is like an Argon
configuration. Maybe it explain the abnormal value you get for the Vlocal
potential



Best regards,

Alexandre
