Dear John,
<div>first of all remember to sign your posts with your affiliation.</div>
<div><br>
</div>
<div>Regarding your problem, the number 1.88972613288564 in the error message looks suspiciously like the bohr<->angstrom conversion. Remember that default units (if nothing else is specified) are bohr in QE, and angstrom in Wannier90 (but it is possible to
switch to bohr, see for instance section 2.4.3 of the manual of Wannier90 2.0 here: <a href="http://www.wannier.org/doc/user_guide.pdf">http://www.wannier.org/doc/user_guide.pdf</a> - or alternatively use angstrom in QE).</div>
<div><br>
</div>
<div>Anyway, it is hard to tell more without the input files you used for QE and Wannier90. Please double check the definition of the unit cell and of the atomic positions in all your input files.</div>
<div><br>
</div>
<div>Best,</div>
