When reading Gaussian cube files

[김현중]

Dear all,

I'm dealing with latest 3.1.8 version of VESTA for MAC OSX.
I have cube file generated with FHI-aims code.

The question are..

Question 1.
In the change log of VESTA release section, it is mentioned that "When reading Gaussian cube files, do not apply periodic boundary condition to structural models any more."
What the above sentence mean? Should I modify original cube data file?
As I know, The cube file format is as follows,

Question 2.
First few lines of my cube file is as follows,

When I extend the boundary (with Command+Shift+B key) with x(max)=2, y(max)=2,
the charge density is properly extended but the atoms are not modified acordingly, I mean, charge density is 2x2 periodicity but 1x1 atomic data is still preserved (not changed).
I remember older VESTA version did not show this kind of problems, what is changed?
Could you send me stable version? (not 2.xx version..)

Sincerely,
Hyun-Jung Kim.
