[Pw_forum] Hubbarb coefficients

[Tommaso Francese]

Dear all QE users, 
even if the question it might be a little bit trivial, can anybody describe, 
step by step, how to extrapolate the Hubbard coefficients, for example a cubic 
structure of ZrO2, with richness of details and defining every parameter set?
 I haven't find a good description in the forum, nope in internet, so this is 
the reason i ask you to help me.
Thanks in advance,
