<div style="direction: ltr;font-family: Tahoma;color: #000000;font-size: 10pt;">Dear all,

<div><br>

</div>

<div>I'm trying to do a fixed spin momentum calculation with WIEN2K. But after finishing the lapw1 stage, I got a message saying</div>

<div> </div>

<div>"awk: invalid -v option</div>

<div><br>

</div>

<div> stop error: the required input file case.in2up for the next step could not be found".</div>

<div><br>

</div>

<div>My cluster is OSX based. And <span style="font-size: 10pt;">a 20070501 version of awk is preinstalled, which is not a gnu awk. So </span><span style="font-size: 10pt;">I doubt the problem is the incompatibility of my awk.</span></div>

<div><span style="font-size: 10pt;"><br>

</span></div>

<div><span style="font-size: 10pt;">Thanks in advance!</span></div>
