# [Wannier] Fw: Re: different initial projection get same wannierisation result, however, the hr.dat has significant imaginary part for many situation

```previous email somehow gets scrubbed. So this is another try.

Dear  Arash,

Thank you so much for quick reply. I previous send email with wrong address. But this mail address is registered. Sorry for the confusion.

Return to the question. I said the final state printed in wout is the same for both cases. Do you mean this part showing Im/Re ratio?

Time to calculate interpolated band structure       0.028 (sec)       Wannier Function Num:    1       Maximum Im/Re Ratio =    0.000006       Wannier Function Num:    2       Maximum Im/Re Ratio =    0.000007       Wannier Function Num:    3       Maximum Im/Re Ratio =    0.000009       Wannier Function Num:    4       Maximum Im/Re Ratio =    0.000008

But this part is also the same for both cases.

I think the question now is not that the WF is not correct. It is that the WF is exactly the same while hr.dat is significantly different.

my .win file is as below. The scf and nscf file is the same as example05. I used 4x4x4 grid. You could check that if you have time, thank you very much
