in real or reciprocal space? in the latter case, you could modify the
"pw2casino" utility. In the former case, you can get the wavefunctions
on the FFT grid by Fourier-transfoming them. The correspondence
between points in real space and indices in the FFT grid is explained
in the FAQ of the user guide. You might try to modify code "elf.f90",
