    <p>For example in line 19:</p>
    <p> -7.61366009-13.18724611    3.04861427  5.28035480  
      -7.61366009-13.18724611</p>
    <p>The space between the real and imaginary part of the last complex
      number is so small that they merge together (and FORTRAN
      complains).</p>
    <p>Maybe simply adding a white space there (and in all the multiple
      places it happens) can solve the issue. <br>
      How did you generate dynamical matrices? If they were done with
      ph.x, then maybe this is a bug that should be fixed (and it should
      be super easy). </p>
    <p>It is also true that, looking at the negative imaginary modes you
      are obtaining, probably something wrong happened, like a very
      under converged choice of the pw.x parameters, a wrong cell or
      atomic positions, etc...</p>

            look into file 6.1141.dyn3: likely you will notice something
