Error message: dis_spheres_first_wann is larger than num_ban

Post by hanwooh »

Dear all,

Hello.

I had the following problems, when I tried to run EPW program for lead examples without spin-orbit coupling.

Error: dis_spheres_first_wann is larger than num_bands-num_wann+1
Error: examine the output/error file for details

Altough I know that Samuel already answered similar problems (viewtopic.php?f=3&t=6), I couldn't figure out why same problems occured again.

Currently, I use latest EPW-4.0.0. (downloaded it on April 2nd) and I also checked that wannier90 is complied properly without any errors.

Could anyone help me with this?

Best,

Woohyun Han.

Dear Woohyun Han,

Depending on which version of QE you have, you can either do:

1) In QE/

Code: Select all

make distclean
./configure
make pwall
make ph
make epw


If the version is a bit old, you can do
2) In QE/

Code: Select all

make distclean
./configure
make pwall
make ph


3) In QE/EPW/src/

Code: Select all

make


Could you do that and tell me if you still have the issue?

Best,

Samuel

Dear Samuel,

I had this same problem. Recompiling cleanly as you suggested solved the problem.

Thanks,
