Cartoon cylindrical helices

The cartoon_cylindrical_helices setting makes cartoon helices appear as simple cylinders.

Changed in PyMOL 2.5: Cylinders are not straight anymore but follow the actual curved shape of a helix. Straight helices are still available as mode 2.

Modes

• 0: Off (helices will be rendered according to the cartoon property or settings like cartoon_fancy_helices)
• 1: Curved helices (since PyMOL 2.5)
• 2: Straight helices

Example

fetch 1bb1
set cartoon_cylindrical_helices, 1
as cartoon

set cartoon_cylindrical_helices, 1	set cartoon_cylindrical_helices, 2

cartoon_loop_quality affects "roundness" of mode 1 curved cylindrical helices (and loops of course).
