Dear users,<br><br> I am trying to calculate the wannier function of perovskite structure.<br>I have gone through the UG and I could able to do the same for the SrVO3.<br>But for my present compounds, I am not getting the same band structure with wien2k and wannier function programme.<br>
<br>I was checking all the output files, and got some difference in the case.outputkgen and SrVO3.outputkgen file, though it has same space group and no of point groups same.<br><br>In my present compounds, It has number of point group = 2<br>
But my first few line of the case.outputkgen looks like<br><br>ortho= T<br> R1 = 9.821100 0.000000 0.000000<br> R2 = 0.000000 9.821100 0.000000<br> R3 = 0.000000 0.000000 9.821100<br> DEPENDENCE OF DIVISION OF TRANSLATION VECTORS IARB= 0 0 0<br>
