[QE-users] hp.x code overestimates Hubbard U value

[Soumyadeep]

Dear QE users,

   I am getting a overestimated value of Hubbard parameters using hp.x 
executable of Quantum Espresso. My material is iron based 
superconductors (LiFeAs) for which "U" lies between 3.0-3.5 eV, but 
using this code I get it around 6.4-6.5 eV.

   Can anyone find out possible mistakes?

with many thanks and best regards
Soumyadeep
