Files do not have the same number of eigenvalues!

Post by qingboyuhen »

Dear all,

I have encountered one problem when I am calculating the prefactor using dymprefactor.pl command. It returns me the following error.

Files do not have the same number of eigenvalues!

I attached my freq.dat files below

Well, we can deal with the error message separately, but first, if you look at your frequencies, the "1" at the end of the line means that the frequency is imaginary. There are far too many imaginary frequencies. Make sure that your displacements are sufficiently small and that your forces are sufficiently accurate (ediff=1e-8), or use the linear response method.

Well, we can deal with the error message separately, but first, if you look at your frequencies, the "1" at the end of the line means that the frequency is imaginary. There are far too many imaginary frequencies. Make sure that your displacements are sufficiently small and that your forces are sufficiently accurate (ediff=1e-8), or use the linear response method.

Thanks Prof. Henkelman! I am using displacements as 0.005 and ediff=1e-8. I am not sure how to use linear response method and what settings I should do. Does it mean that I should use the VASP settings as IBRION=5 and LEPSILON=.TRUE. ? Hope I can get your help for this. Besides, if 1 means that they are imaginary frequencies, I should have only one imaginary frequency in my TS structure and none in stable structures if they are reasonable.

I attached my input as below. Hope I can have some advice from you. Thank you very much!

Check to see if you calculation completed the entire 199 iterations. Also check the Hessian matrix (generated from dymmatrix.pl) to see if there are any zero entries at the end (which there will be if the calculation did not finish). With so many negative modes, something is qualitatively wrong.

By linear response, I mean density functional perturbation theory (IBRION=7 or 8)
