Dear Zongyi Wang,
for whatever reason, the num_bands is commented out in this example; wannier90
will default to num_bands = num_wann, which is then inconsistent with the value
defining the contents of (and written at the top of) the .mmn file.
I guess that if you uncomment num_bands, the case should work. We will update
the tutorial accordingly for the future.
Yours, Jerome

however, when I run wannier90.x ,after the scf , nscf, wannier90.x -pp
and pw2wannier.x command is finished. it shows the error:
benzene.mmn has not the right number of bands
Where should I change my code? Could you please help me?
Thank you very much!
