hi EPW user

I want to calculate the TC of 2D-NbS2. After nscf.in and scf.in are completed, there is an error in running epw.x

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
Error in routine wannierize (1):
inconsistent nscf and elph k-grids
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

However, nscf and epw are consistent

nscf.in:

&control

Hi yq_zhao,

Please replace the following line in your epw.in, because you are missing ' at the end of the line. Because of which, code could not read the later input flags correctly.

wdata(6) = 'bands_plot = .true.'

This should work fine now.

Best,
Hari Paudyal

thanks for your repeat, my problem has been solved.

Hi ,Zhao,
I meet the same error but I can not solve it, Can you give me a help how to do ?
Thank you
Kong
