[PyMOL] Helices as cylinder and ribbon - both in a single representation

[Abhinav Verma]

Hello,

I wish to show one chain in cylindrical helices, while the other one in
ribbon representation. How can I achieve this with pymol.

thanks in advance,

If the two chains are in one object, then you need to split them into two
objects. So if I'm working with the PDB file 1dvi, something like:

create cha, 1dvi & chain a
create chb, 1dvi & chain b

Then I can type:

set cartoon_cylindrical_helices, 1, chb

To make the chain B object have cylindrical helices, while chain A will
remain with the ribbon-style.

Cheers,
