[Wien] How to Write the struct file??

[liuzw03 at st.lzu.edu.cn]

Dear wien users,
As we all know, the *.struct file is one of the basic files in the wien programs.
But could anyone tell me how to input the corresponding atom coordinates and
spacegroup?It's so difficult to accomplish the task that I can't continue my
recent work about YBO3:Eu.
Thank you for your help.


sincerely yours,
