1This example tests ph.x together with PAW. 2 3The calculation proceeds as follows: 4 51) make a self-consistent calculation for C 6 (input=c.scf.in, output=c.scf.out). 7 82) make a phonon calculation for C at the Gamma point (input=c.phG.in, 9 output=c.phG.out). 10 113) make a phonon calculation for C at the X point (input=c.phX.in, 12 output=c.phX.out). 13 144) make a self-consistent calculation for ch4 in a small box 15 (input=ch4.scf.in, output=ch4.scf.out). 16 175) make a phonon calculation at the Gamma point (input=ch4.phG.in, 18 output=ch4.phG.out). 19
