[ase-users] Attribute error with positions

[Iyemperumal, Satish Kumar]

Hi Abhirup

I use the following

list = []
s = read("fname.POSCAR")
for i in s:
list.append(i.position[2])


Best,
Satish

Subject: [ase-users] Attribute error with positions

Hi All,

I am trying to get the inter layer distance between the layers of the surface slab from using the
CONTCATR of the VASP .

But when I am trying to read the z-coordinates of the atoms using 'positions' attribute
I am getting the error as -

AttributeError: 'file' object has no attribute 'positions'

Here is what i have imported in my code-

import ase.io<http://ase.io>
from ase import Atoms
from ase.io<http://ase.io> import read
from ase.io<http://ase.io> import write
from ase import *
import numpy as np

Can anyone please give me any idea where I am going wrong ?

Thanks,
