Dear Pwscf users,
I am doing a scf calculation of Al(OH)3. At the very beginning of the output
file the warning come as:
Warning: card &IONS ignored
Warning: card ION_DYNAMICS = 'DAMP', UPSCALE=20.0, ignored
Warning: card / ignored
Warning: card &CELL ignored
Warning: card CELL_DYNAMICS = 'DAMP-PR', PRESS=0.0, ignored
Warning: card / ignored
warning: symmetry operation # 6 not allowed. fractional translation:
-0.5000000 0.0000000 -0.4717471 in crystal coordinates
This is the input file:

From the previous posts, it looks like the symmetry warning is halmless? I
have no idea about thoese card warnings. Could you please give me some help?
Thank you in advance !
