Dear Prof. Blaha:<br><br>First I did mBJ calculation there are no errors. Then I did SO calculation and I got the error:<br><br><pre>hup: Command not found.
LAPW0 END
0 LAPW0-Error. Check file lapw0.error and case.output0*.
LAPW0 - Error. Check file lapw0.error.
> stop error<br><br>The lapw0.error is as following:<br><br>Error in LAPW0<br> 'LAPW0' - case.grr file not present, which is requred for mBJ<br><br>When I open case.grr I found there is only a line of stars. At the position after mBJ calculation and before SO calculation there is a number. For GGA+SO calculation there are also <br>
no errors reported. What is the problem.<br><br>Thanks!<br><br></pre><br>
