Dear sir,
 
During  the anaddb calculation I let the eivec parameter equal to 1 .I got 
the 
Eigendisplacements.  How could  I get the eigenvectors? Does the square root 
of the mass multipies the eigendisplacement equal to the eigenvector?If it is 
so, and the masses is given in atomic mass units then what is the unit of the 
eigenvector? In addition,what controls the quality of the eigenvector?

Best regards,
hu
