[Pw_forum] No symmetry found

[efi dwi indari]

Dear all,

Currently I am calculating the electronic structure of Hybrid Perovskite
solar cells. The actual structure is tetrahedral but according to a
reference it can be approximated with simple cubic structure. Thus, I set 5
high symmetry k-points (gamma, X, M, R, and again gamma) in the input file.
When I run the program, I got 'no symmetry found' notification in the
output file.

After a short discussion with my colleague, the choice of the k-point could
lead to this error. Then, I deleted the gamma k-points since there was an
error led by gamma k-points in the previous calculation. However, I still
got the same error message.

I have googled the problem and I found this
http://qe-forge.org/pipermail/pw_forum/2011-August/096070.html
and this
http://qe-forge.org/pipermail/pw_forum/2011-August/096074.html

Yet, I am sorry, I could not get the solution from the later link. .

Below attached my files (both input and output) to have an idea about my
system.

Thank you in advance. Any help would be really appreciated.
