<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
anomalous. The error message also tells you where the "bad
real number" is read<br>
