for your reply. I am not switching from fixed to tetrahedra method, both
the methods were used separately. I want to use tetrahedra method to
calculate the DOS. When use the occupations=tetrahedra, I am getting
the above specified error. <br><br></b></div><b>Regards<br></b></div><b>N. Yedukondalu</b><br><br><div dir="ltr"><div><div>Dear Users and Experts,<br><br></div> I am using QE v.6.1. I ran DOS calculation for Silicon using Occupations='fixed' in 'scf' and 'nscf' calculations and it was finished successfully and dos output file is created. However, when I used occupations='tetrahedra' in nscf (both scf and nscf), the dos.x calculation was terminated with the following error (I have tried for couple of systems apart from Si). Now, my question is how to use occupations='tetrahedra' in scf and nscf calculations to compute the DOS for any system.
