Dear Bezzaoui Iman,
Try to use the HP code with the input parameter find_atpert=3 (keep nosym=.true. and noinv=.true. in the pw.x input). This should perturb all atoms. Note that you already have the response from perturbing 13 out of 34 atoms, so keep it (the files are in the temporary directory). Then you can perturb the remaining atoms using perturb_only_atom (see HP/examples/example06). This way is computationally expensive. You can try another option. Enable symmetries (nosym=.false. and noinv=.false.), optimize better the structure, and using find_atpert=1 try again. Use QE7.0. If the problem is still there, you can adjust the new parameter dist_thr in the HP input.
