 Dear all users:

   How to obtain the wavefunction from _WFK file  ??
I've known cut3d can help me to do this , but I don't understand the data I 
get
after
using cut3d is coefficients of wavefunction or wavefunction itself ??

  Besides,  the binary codes in _WFK  contains  planewaves coefficients of all
the wavefunctions of certain nth band and certain k-point. Dose any program
transform this unformatted data file  into formatted data file I can read , 
and
by which we don't utilize the cut3d ???   Thank you.
