Hi, 
based on my little knowledge of abinit src code, fofr(1,:,:,:,:) is the real part of wavefunction, not the coefficient.

You may confirm it from last part of wffile.F90, since the density is just written as fofr*fofr.

dear users:

In the file ' wffile.F90 ' , " fofr(:,n1,n2,n3) " is the output data of
_WFK file after using cut3d .fofr(1,n1,n2,n3) = real part , fofr(2,n1,n2,n3) =
imaginary part

the comment in this program says the fofr(:,n1,n2,n3) is the wavefunction.
I wonder that fofr is value of wavefunction on each grid point in real space
or
coefficient of planewave on each reciprocal lattce G ???

I have obfuscation with these two things for a long time.
which statement is correct?? Thank you all



best regards
