[QE-users] Calculate the phonon of the same structure with different input form

[zhenqing li]

Dear all,
I calculate the phonon of the same structure with different input form
first is
"
ATOMIC_POSITIONS crystal
C            0.0000000000       0.0000000000       0.0000000000
C           -0.2500000000       0.7500000000      -0.2500000000
CELL_PARAMETERS angstrom
     -1.7575165746       0.0000000000       1.7575165746
      0.0000000000       1.7575165746       1.7575165746
     -1.7575165746       1.7575165746       0.0000000000
"
second is
"ATOMIC_POSITIONS crystal
C            0.0000000000       0.0000000000       0.0000000000
C            0.2500000000       0.2500000000       0.2500000000
CELL_PARAMETERS angstrom
0.0000000000    1.7575165746    1.7575165746
1.7575165746    0.0000000000    1.7575165746
1.7575165746    1.7575165746    0.0000000000
"
in fact they are the same structure
and all the other information is the same
but the phonon band of them are very different
