Let's suppose I've already run an scf calculation for an input file. Now I can read the wave functions and with ph.x I can get the dynamical matrices. I'll get as many files as the number of q-points I've chosen named like "MoS2.dyn0" , "MoS2.dyn1" , "MoS2.dyn2" and so on.
If I stop the calculations and get only the first 3 dynamical file could I still use q2r.x and plot the dispersion relations with matdyn.x or I will get error because I have stopped manually my calculation?
