Hello It is hard to say what happened without a look at the outputs. Could you send the output of the nq=3,3,3 calculations? One hypothesis that it is better to check is that you first did the calculation with nq =2,2,2 and then the one with nq = 3,3,3 using the same prefix. Because recover is set to true, the program could have been detoured by possibly preexisting status files it read trying to recover data from the previous calculation.

The files are created, but are empty. I have tested this with QE-7.3 and QE-7.0. Can you kindly help me with understanding why? My ph.in is as follows: -- &inputph prefix = 'H3S_270_2x2x2', fildyn = 'H3S_270_2x2x2.dyn', amass(1) = 32.065, amass(2) = 1.00794, outdir = './' ldisp = .true., trans = .true., fildvscf = 'dvscf', nq1=3, nq2=3, nq3=3, tr2_ph = 1.0d-14 recover = .true. / For (nq1, nq2, nq3) = (2,2,2) I do get meaningful dynamical matrix files. Best, Soham Ghosh.
