Dear Meysam,
I have recently generated a Bi pseudo potential using the input below. See
if this works for you.

Dear QE Users,
I am not sure if this possible bug is QE related or EPW related so let me try
reporting it here. I have installed espresso-5.4.0 and EPW-5.4.0 in my $HOME on
a Linux cluster using intel-14.0.2 and openmpi-1.6.5. To calculate the
electron-phonon scattering rates for a 2-atom
Dear QE users and developpers,
I would like to compute phonon properties using the finite displacement
method, as proposed in the example of quantum espresso version 5.1
(PHonon/FD/example). For frequencies at q=0, the answer is reasonably close
to the results of DFPT, but for q-vectors different
Dear all QE users and developers,
I want to do a cell optimization (vc-relax) but I keep getting the following
error:
task # 0
from ggen : error # 150
g-vectors missing !
I also have tried changing the ecutwfc as well yet, It gives me the same error.
When I look at
OK, I used 5.3.0... I will definitely use this feature in future...
Thanks for the clarifications Andrea & Paolo!

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

In the latest version (the one just released), positions that require three
parameters can be specified either as "Si 8c x y z" or as "Si x y z".
Moreover, a bug was fixed.

Dear ouyang,
First of all, I am not expert regarding the same query, other can throw more
light on it.
I think the following link of Pw_forum may be helpful regarding the same query.

Thanking you,

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

Dear Paolo,
thanks to this conversation I learned that one can use Wyckoff position
in QE - when was it implemented?
Anyway, I directly wanted to try it with a system I'm studying just to
realize that it is not working...
Space group 62 (Pnma) has only the Wyckoff position 4a, 4b, 4c
Hi,
I am getting an error "S matrix not positive definite" when I am trying to
do a nscf calculation for band structure of unit cell MoS2 after a
successful scf run. The same input file (both for scf and nscf ) ran
successfully with pw.x version 5.3.0
Attached is the input file for nscf
Hi.
Maybe you can compare your input with the one for Bi in the PSLibrary by Andrea
Dal Corso.

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.

Dear users and developers:
I want to reproduce the band structure of paper:Ultralow thermal conductivity

First I relax the structure, then I got the lattice parameter pretty similar to
the paper.
Then I try to plot the band structure

I am trying to make a full relativistic psudopotential for Bismuth by
Atomic code.
As far as i know there is no full relativistic psudopotential in the
quantum esspresso website for Bismuth.
All electron calculations was successful but I got an error from atomic :

Dear Vishal,
In "vc-relax" (vc stands for variable cell) calculation the cell is also
relaxed to a target pressure.

Dear Dr. Giannozzi and Dr. Axel,
Thank you very much for the help. I will try to do what you said and see if
it works.
