Dear. Julian

I have two questions

[1] in xxx.eig file. like below

as shown in the capture,

For (1) from the second line , are (1) relaxed equilibrium positions of atoms and are (1) same with the atomic position of input?

[2] is it possible to calculate the displacements of each atom as mode?

[3] Can I calculate the cartesian or fractional length by converting eigen values using some method?

I know that the the components of x y z of atoms at each mode are the relative size and direction of vibration. is it right? are those component of eigenvector could be converted to dispalcement(u)?

ex u=1/sqrt(M)*eigenvector

Thanks
