Dear all wien developers and users,<br>I intend to perform the AFM calculation for one of my selected system which has single Co atoms in unit cell. For this, I generated a supercell with (2x1x1) which generates 4 Co, 4 Sr and 8 oxygen atoms. With this structure file, when I initiated the initialization, <b>warning appears with multiplicity not equal. </b><br>
Then I initiated with the new structure (as asked by the software). The new structure is shown below: <br><br>P 4<br> RELA<br> 14.348318 7.174159 23.597208 90.000000 90.000000 90.000000<br>

<br>Now my question is, within this structure file, <br>(i) How to flip the spins in <b>instgen_lapw</b> from the positions as there is only single Co atoms with 8 positions. <br>(ii) How can we check the directions of provided spins in xcrysden<b><br>
<br></b>By the way, I also tried to run without allowing the new structure file. Then it gives an error when I run dstart. The error are Rotdef not defined. <br><br>Pls help me to solve this issue.<br>Thanks in advance<br>
