Did you know... 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 Related Settings cartoon_smooth_cylinder_window: half-window size for window average smoothing (mode 1) cartoon_smooth_cylinder_cycles: number of cycles for window average smoothing (mode 1) cartoon_loop_quality affects "roundness" of mode 1 curved cylindrical helices (and loops of course).
