Well, I'm not sure what you mean by wave functions and what you want to
do with them.
a) The vectorfiles, contain the "eigenvectors", i.e. the coefficients in
front of the APW-basis functions. Of course, one needs those
coefficients to calculate psi(r), but this is not straightforward in
your own program.
If you want the coefficients in "readable" form, put WFPRI into case.in1
and you will find them in case.output1 (can be huge !)
b) the program lapw7 can calculate wavefunctions psi(r) on a grid in a
plane through the crystal. However, also here you have to decide on
real/imaginary/modulus of psi, which is in general a complex function.
c) In lapw2 with the switch ALM you can write radial functions and A_lm,
B_lm,.. to a file. This could be used in an external program to get
psi(r) (inside spheres) and using the coefficients * e^(ikr) you can get
in in the interstital.

Dear Sir:
I am running the wien2k code parallelly on a local machine with 28 cores
to analyze the interfacial properties of dichalcogenides. To calculate a
few quantities we need the wavefunctions. Though the wavefunctions are
written in the vector files, they are not readable (binary files). Is
there any other way to generate readable files containing wavefunctions?
