Dear Ali,
thanks a lot for the warning I will select carefully pseudopotentials for the future!
Best regards,
Mauro.

Dear Mauro,
My reply is going to be only a warning about your Fluor pseudopotential and not related to the error you get in case you get your pseudo from QE-website. There was a cdiaghg error reported in January about those pseudopotentials
(C 12.011 C.pbe-van_bm.UPF,
F 18.998 F.pbe-n-van.UPF,
H 1.00794 H.pbe-van_bm.UPF).
and below is Paolo's reply regarding the error reported:

For sure, we did not know exactly which one of them was not good and I don't know if the Fluor pseudo is good or not. Thus, at least one of (C.pbe-van_bm.UPF, H.pbe-van_bm.UPF) is not good!!!
Best,

Subject: [Pw_forum] Error with neb.x
Dear all,
sorry for disturbing but I cannot find a solution in the mailing list.
I'm trying to use neb.x to simulate the diffusion of a F vacancy in a LiF crystal. The run calculates well the first two images and then exit at the third with the error:
Error in routine set_sym_bl (1):
Symmetry group not a group! Use standard orientations for axis
How can I fix this problem?
My input is reported below.
Thanks a lot and best regards,
Mauro Sgroi.
