Dear QW users ,

I want to build a MoS2 nanotube , I do exactly like the tutorial on youtube but the result is not like that video !
Can you please let me know what the problem is ?

Thanks in advance .
Regards,
Saeed.

You may miss one step, i.e., the transformation of a hexagonal unit cell to an orthorhombic cell. 
In order to wrap an atomic sheet into a tube, it is better to first expand such sheet in an orthorhombic cell.

Hi .
Thanks for your reply .
Fortunately I could do that !
I also need to have MOS2 slab .
Can you please do me a favor and let me know how I can build it ?
(Some hints are enough !)

Thanks a lot .
regards,
Saeed.

Have you follow the steps listed in the following tutorial to construct the MoS2 slab and tube?:

In the 5th step of Instructions in the above link,  it shows how to do the transformation from hexagonal unit cell to an orthorhombic supercell.
