Re: [Phonopy-users] ValueError: invalid literal for int() with base 10: '=2'

In addition to the example of Eugene, –dim=“2 2 2”,

% phonopy -d –dim 2 2 2 -c POSCAR_unitcell

also works if my implementation of phonopy is correct.

I already optimized my unit cell structure, then copy CONTCAR into POSCAR, then run: phonopy -d –dim = “2 2 2” -c POSCAR_unitcell. However, I got the error which is shown below. Since I did the similar thing last week using Phonopy,  I don’t know what’s wrong this time and how to fix this. Very appreciate if anyone can give me a hint. Thank you very much.
