You can easily verify what is wrong by looking at what happens at line 97 of bands_FS.f90. Note that since v.5.3: * Old Fermi Surface plotting tools kvecs_FS.f, bands_FS.f90, in PW/tools/, replaced by new code PP/src/fermisurface.f90 P. On Tue, Apr 26, 2016 at 10:22 AM, oyxf328

Dear A.Anandaraman, EPW is only parallelized over k-points. You therefore need to run it with -npool. In your case it would be something like: mpirun -np 4 XXX/epw.x -npool 4 < input_file. Please note that the version 4 of EPW is now available in the QE 5.4.0 package. Best, Samuel On 25

it is not noise, just wrong eigenvalue sorting, so that because the plotting program connects consecutive points, if one point belongs to a band and the next one to another one, you’ll see lines connecting different bands that appear as noise. See here:
