Dear all,

I am running EPW for a system where exclude_bands have to be used and I am getting the 'famous' error:

" Error: dis_spheres_first_wann is larger than num_bands-num_wann+1". I have read that I need to download the developers version of Wannier90 and this should solve the problem. I just want to ask how to proceed after downloading it. I have the ZIP file of the version. Shall I put in QE/archive and then trick QE by changing both the extension to tar.gz and the name to wannier90-2.1.0? since whilst compiling QE will automatically unzip the 2.1.0 version.

Thanks for the help in advance

Please try the latest version QE6.4 with EPW5.1 and see if the problem still appears.

Dear Roxana,

Sorry for the late reply. It worked with QE-6.3 and EPW5.0 by using the developers version. I am running some calculations at the moment with these versions. When they are done, I will donwloaded the latest versions and if the problem resurfaces , I will let you know.

Thank you
