<p>Dear Pablo,</p>
<p>Thank you for explaining your point. Now I understand. <br>

<p>With best regards </p>

<p>Dear Tomas</p>
<p>Are you a hokey player? I suppose not!<br>
</p>
<p>The problem with this is that the cell goes from CXY to P then in the cell the number of atoms doubles.</p>
<p>What I did is to see the positions of the changes of the atoms with sgroup</p>
<p>Before sgroup:</p>
<div> 1: X=0.50000000 Y=0.00000000 Z=0.63000000<br>
2: X=0.00000000 Y=0.00000000 Z=0.63000000<br>
3: X=0.50000000 Y=0.25000000 Z=0.38122315<br>
3: X=0.50000000 Y=0.75000000 Z=0.38122315<br>
4: X=0.50000000 Y=0.25000000 Z=0.87877685<br>

</div>
================
<p>As you can see</p>
<p>a=>c</p>
<p>b+c=>a</p>
<p>c=>b</p>
<p>then you can see how the atoms split, for example <br>
</p>
<p><span>atoms '3' split into '3' and '4'</span><br>
</p>
<p>atoms '17' split into '21' and '22'</p>
<p>one have to take into account that the original structure is <br>
</p>
<p>CXY and a,b are equivalent to a+.5,b+.5</p>
<p><br>
</p>
<p>The <span>b+c=>a</span> is the consequence of the 90 => 135 degrees</p>
<p><br>
</p>
<p>I would be easy to make a program to change 135 => 90</p>
<p><br>
</p>
<p>Thank for your comments</p>

<div>Dear Pablo, <br>
I tried to play with your structure and I succeeded. <br>
First, run <br>
x supercell <br>
always one cell in x- y- and z- directions <br>
zero shift in all directions <br>
Enter your target lattice type:<br>
P <br>
(you must choose primitive lattice in order to break <br>
the symmetries you do not want there). <br>
Zero vacuum in all directions. <br>
Then <br>
cp TiO2-sup_super.struct TiO2-sup.struct <br>
Edit the TiO2-sup.struct file and find the two Cu atoms. <br>
Rewrite the space after first Cu to 1. <br>
Rewrite the space after second Cu to 2. <br>
Or do these two things comfortably using w2web. <br>
You must have them inequivalent. <br>
By the way, are you sure that the vacuum you have for your slab is <br>
sufficient? When I use slabs I try to have vacuum around 20 bohrs. <br>
Then run <br>
x sgroup <br>
By checking TiO2-sup.outputsgroup you see that sgroup has chosen <br>
monoclinic lattice but with all three angles equal to 90 degrees. <br>
(Space group 56 6 Pm) <br>
Then, I STRONGLY RECOMMEND TO ERASE ONE OF THE Cu ATOMS, <br>
probably the one at the position 0 0 0. <br>
It worked on my computer. <br>
HTH <br>
Tomas <br>
