<DIV> </DIV>
<DIV>I have done the MBJ calculation for a simple perovskite system without spin-polarization successfully. But when I tried for the spin-polarized case for the same system it shows an error after running the following line:</DIV>
<DIV> </DIV>
<DIV>run_lapw -NI -i 1</DIV>
<DIV> </DIV>
<DIV>The error is </DIV>
<DIV> </DIV>
<DIV>Error in LAPW1</DIV>
<DIV> </DIV>
<DIV>"INILPW' - can't open unit :18</DIV>
<DIV>'INILPW' - filename : case.vsp</DIV>
<DIV>'INILPW"- status:old form: formatted</DIV>
<DIV>'LAPW1' -INILPW aborted unsuccessfully.</DIV>
<DIV> </DIV>
<DIV>Is this possible to do the MBJ calculation for a spin-polarized case.</DIV>
<DIV> </DIV>
<DIV>Please help me to resolve this problem.</DIV>
<DIV> </DIV>
<DIV>With kind regards</DIV>
