<DIV>Dear Wien users,</DIV>
<DIV> </DIV>
<DIV>I am calculating optical properties including spin-orbit using about 12,000k-points in the IBZ.. I have followed the procedure in the UG. However, when I got to x opticc -so -up, it crashed with following error message:</DIV>
<DIV> </DIV>
<DIV>Allocate error 491: Array is already allocated</DIV>
<DIV>In procedure: mom_mat</DIV>
<DIV>At line : 240</DIV>
<DIV>End of diagnostics.</DIV>
<DIV> </DIV>
<DIV>Also, when I did the same calculation without spin orbit interaction, </DIV>
<DIV>it did not crash</DIV>
<DIV> </DIV>
<DIV> </DIV>
<DIV>Please , I am looking forward to your kind assistance</DIV>
