Dear Arash,<br><br>Thanks for your reply.<br><br>1) I restarted and
redid all the calculations using the same number of digits after the
decimal point for the unit cell parameters in both PW and Wannier input
files<br>=================== in PW nscf file<br>CELL_PARAMETERS cubic<br>
4.679498062, 0.0174869403, 0.0000000000,<br>
0.017486940, 4.6794980620, 0.0000000000,<br>
0.000000000, 0.0000000000, 14.8645406842,<br>================= in Wannier input file<br>
begin unit_cell_cart<br>4.67949806203093 0.01748694030527 0.00000000000000<br>0.01748694030527 4.67949806203093 0.00000000000000<br>0.00000000000000 0.00000000000000 14.86454068421497<br>
end unit_cell_cart<br>=====================<br>2)Unfortunately, the same error message appears when using pw2wannier90.x:<br>-----------------<br> *** Reading nnkp<br> -----------------<br><br> Checking info from wannier.nnkp file<br>
<br> Something wrong!<br>
<br> rlatt(i,j) = 14.8645417730346 at(i,j)= 14.8645406842150<br>============================<br><br>I am wondering if what I did was the right approach to fix the problem or not.<br>
Another guess is that the internal precision of calculations/output
results by pw.x is somehow different from what wannier90.x and/or
pw2wannier90.x expect.<br><br>Regards,<br>
