Hi everyone.
I solved my problem. I made the calculation one more time, but in this
case firstly I calculate the wannier functions, only the wannier
functions. After that I changed the keys in order to calculate the bands
and the hamiltonian, only the bands an the hamiltonian (Here I extracted
"wannier_plot = .true." and
"wannier_plot_supercell = 1). In this case the simetry of the wannier
functions was consistently with the value of the locals hoppings.

I am trying to understand the results of wannier90. I looked the
Hamiltonian and found that the symmetry of the hoppings are incompatible
with the simmetry of the wannier functions. Mi system is graphene with
an absorbate and this problem appears around the vecinity of the
absorbate. More specifically the problem is the hopping between the
absorbate orbital's and the Pz orbitals of graphene.
I would like to know in which basis the hamiltonian was written. I dont
know if exist an order to run the wannier90 code to get a hamiltonian
compatible with the wannier orbitals.
I attached my code, I calculated the wannier orbitals, the bands, and
the hamiltonian in the same run.
First I runned in wannier90.x:
num_bands = 154
num_wann = 84
dis_win_min = -26.d0
dis_win_max = 11.d0
dis_froz_min = -3.5d0
dis_froz_max = 0.0d0
dis_num_iter = 50000
num_iter = 50000
num_print_cycles = 10
search_shells = 64
conv_window = 3
guiding_centres = .true.
num_guide_cycles = 1

Then I use the pw2wannier90.x
after I run one more time the wannier90.x with the same input.
and finally I changed the input of the wannier90 by (I added commands to
calculate the wannier functions, the bands and the hamiltonian):

num_wann = 84
dis_win_min = -26.d0
dis_win_max = 11.d0
