High T SrTiO3 phonon calculation &inputph tr2_ph=1.0d-15, !very important threshold parameter. Check and lower (=stricter) this if phonon calculation is wrong prefix='SrTiO3_1', !must be the same as the pw.x scf calculation max_seconds = 3300, !55mins !search_sym=.false., recover = .false., !change to true if you are breaking the calculation into irreps (false only for the first irrep of each q point) outdir='Output', fildyn='dynMatOutput.dyn', !file name for the dynamical matrix output file ldisp=.true., nq1=2, nq2=2, nq3=2, start_q=1, !can be used to break up a long ph.x calculation into manageable bits, prevent complete data loss in case the program crashes last_q=1, /
