[Wien] structure file

Almost certainly this is because you are not setting up the
structure(s) correctly. When you enter atom positions you need to have
these correct to 8 numbers after the decimal point for special
positions. For instance "0.33330" is not correct for 1/3, it has to be
0.33333333.

Look at what the different files being produced, read the output in
the log files and it will all be in there.
