Dear Dr. Elie Moujaes,
No, it should be the first column real part of x, second column real part of x,
third and fourth real and imaginary part of y, and so on..

Dear all,
I have a naive question (only to make sure) regarding the format of the phonon
eigenvector at a certain point q, produced in the .eig or (matdyn.modes)
file(s).
Let us take a phonon wave vector:
q = ( 0.000000041 -0.288465197 0.000000000 )
**************************************************************************
freq ( 1) = 2.149626 [THz] = 71.703791 [cm-1]
( -0.000000 0.000000 -0.000000 0.000000 -0.010327 0.000000 )
( -0.000000 0.000000 0.000000 0.000000 -0.554305 0.000000 )
( -0.000000 0.000000 -0.257860 0.000000 0.210723 0.000000 )
( -0.000000 0.000000 -0.213878 0.000000 -0.435522 0.000000 )
( 0.000000 0.000000 0.257860 0.000000 0.210723 0.000000 )
( 0.000000 0.000000 0.213878 0.000000 -0.435522 0.000000 )
Does the 1st column represent the real part of the displacement vector along
the x direction, the 4th column is its imaginary part, the 2nd column is the
real part of the y component, and the 5th column is its imaginary part, and so
on?
Thanks
