Dear Professor Baroni

Sorry if my question is so trivial. 
I think Reciprocal space is Fourier transform of the real space so as theIFCs.
When we calculate Harmonic IFCs there is  a command called q2r.x which converts 
reciprocal space IFCs to real space by taking Fourier Transform .
But in the case of harmonic IFCs this is not the case. For my work i need 
an-harmonic IFCs  in real space that whys i wanted to know whether Quantum 
espresso calculates those in real space or reciprocal space. 



Thanks a lot for your response





Regards
Tribhuwan
