Thanks for your reply.

Actually, when I try to run my calculations I get the following message:
Coordinate file <auBulk.xyz> not found.
However, I'm sure it's in the right directory and it's the right format.
And have no idea how to fix it.
I think this problem is not correlated with the cell I'm using, but it made
me wonder about which unit cell should I use and its size.

Do you have any idea what could be the problem?

I'm sending in attachment the coordinate file I'm using. I've already
changed the unit cell size.

Yours sincerely,

Lucas Bandeira
