Dear Paolo,
sorry for bothering you again.
Now I fixed the version of pw.x and ph.x (I'm using for both version 6.5)
and checked the atomic positions in the input file.
I'm able to use dynmat.x only if I use cif2cell to generate the input,
ibrav=0 and explicitly the cell vectors.
If I use spgroup and A, B, C, cos(beta) or celldm(1), celldm(2), etc, ph.x
writes celldm(i) values different than those generated by pw.x.
Here is my new input file:
&CONTROL
title = 'Li2TiS3_monoclinic'
pseudo_dir =
'/workhpc/FCA/FCA_CRF_STRUT/sgroi/DATABASE/ESPRESSO'
prefix = 'LTS_mono'

Could you please help me to solve the problem?
Thanks a lot in advance and best regards,
