Dear all,
I would like to draw my polymer chain like the picture I attached here. I used Graphics -> representations-> Drawing style -> Tube
But, when I choose Tube my simulation box disappears and shows nothing. What's the problem? How could I draw Tube style?
Thank you very much
As far as I know the tube representation draws the Calpha from the protein and connects them. An easy way to circumvent this issue would be to change the atom type of your polymers to Calpha, and try it.
Good luck!
You can set the simulation box with this command: Extensions > TK console > pbc box
Most of the VMD representations depend on specific atom types. You can simply check the documentation.

Therefore tube is only available for protein Calpha as Pablo Galaz-Davison said or phosphate atoms in nucleic acid.
