<p>I am a novice wien2k user. I am running wien2k version 14.2 compiled with intel compilers on machine with Centos operating system. I am trying to use <span name="searchHitInReadingPane" id="0.2690983379985422" class="">wien2wannier</span>
interface to get MLWF. I have been struggling with a strange bug. I know this bug has been floating around for a while.I would really appreciate your input.</p><div>So, here is my problem:</div><div><br></div><div>The crystal I am working is Zr2Te2P which has rhombohedral lattice
structure and has inversion symmetry. First I performed spin polarized
with spin orbit coupling DFT calculation and as per the direction in the
manual of w2w, I performed following steps:<br></div>
<p> ->prepare_w2wdir dft_dir wannier_dir</p>
<p> ->cd wannier_dir ; then init_w2w</p>
<p> -> x lapw1 -up -p ; x lapw1 -dn -p</p>
<p> -> x lapwso -up -p</p>
<p> -> x w2w -up -so -p</p>
<p>In this step, I get error like: <br></p>
<p><i>forrtl: severe (39): error during read, unit 9, file wannier.vectorsoup_1</i></p>
<p>and similar error for the down spin.</p>
<p>Strangely, I did not get this error for bcc iron when I was
trying to reproduce the example 18 result in the Wannier90 manual. </p><p>However I tried the similar thing for BaTiO3 crystal (by using the struct
file given in the lambda0 directory of BerryPi package) . And, I got the
same error. I wonder if this error occurs only for crystals with certain symmetry.</p>
<p>The strange thing is w2w works fine without spin orbit coupling for all of the above crystals.<br>
</p>
<p>I would really appreciate you feedback.
