    Dear Oleg,
    <div class="moz-forward-container">
      <p>It's not happening with only one case. I've tried it for the
        very simple FeSe (attached case), trying to unfold with 2:2:1,
        but also for Sr2IrO4 or SrIrO3 (the case I'm interested in at
        the moment, also attached) or your examples. Everything works
        fine in complex mode, but not with another switch.</p>
      <p>For example both FeSe and SrIrO3 have inversion symmetry and do
        not require complex calculation, but if I run the case in real
        mode, fold2Bloch recognizes well it's a real case.vector (it
        asks for the -r switch), but cannot process it (segmentation
        error). <br>
      </p>

            <div dir="ltr"><span>Dear users,</span><br>
              <span></span><br>
              <span>I have recently installed the fold2Bloch procedure
                from Oleg Rubel and it works beautifully for complex
                calculations. Thanks a lot for this procedure !</span><br>
              <span></span><br>
              <span>However, I have a problem when using a real case. I
                systematically get an error message at the processing of
                the first k point : "forrtl: severe (174):SIGSEV,
                segmentation fault occurred".</span><br>
              <span></span><br>
              <span>It is not a problem with the case.struct or memory,
                because if I force the same case in complex mode, it
                works fine.</span><br>
              <span></span><br>
              <span>Also for spin-orbit calculations, I have an error at
                the processing of the second k point : "allocatable
                array is already allocated".</span><br>
              <span></span><br>
              <span>I have no idea where the error could come from and
                would appreciate help. I compiled fold2Bloch with ifort.</span><br>
