Dear all QE users and Prof. Guido Fratesi,

I have a doubt...
Electron localization function calculations does not make
much sense when using ultra-soft pseudopotentials.

Is it true? although USPP takes into account the charge removal due
to smoothness of pseudo states  by adding augmentation charges.

regards,
sonu
