Cartoon oval pymol

Overview. Only relevant when oval (default) helices is turned on, see Cartoon_Helix_Settings set cartoon_oval_width defines the width of the helix. Synta Overview. Only relevent when oval (default) helices is turned on, see Cartoon_Helix_Settings.set cartoon_oval_quality defines the visual quality (the number of points defining the oval) of the helix. The default setting is generally optimal, increasing improves quality marginally, where as quality drops significantly if the value is decreased a lot (see the black edges below) Example of Cartoon Multi-level Transparency. The near cartoon has transparency setting 0.2, the segment in the BG 0.5. One can make different cartoon selections have different transparency values, in PyMOL. The trick here is to use create or extract instead of select. Create makes new objects that can have independent settings while.

cartoon_oval_quality (integer, default: 10) cartoon_side_chain_helper (boolean, default: off) controls whether or not PyMOL will hide backbone lines and sticks when the cartoon representation is visible as well as disabling smoothing for C-alpha coordinates for residues whose side chains are shown Re: [PyMOL] Cartoon_oval_length. 1) Go to Settings in the menus and choose Edit all. In the new window that appears type oval in the search box. Double click the default value for cartoon_oval_length, enter your chosen preference, and hit the enter key on your keyboard. You should see your change To change the size of the cartoon helices when not in the fancy helix mode you change the dimensions of the oval that represents the cross section of the default cartoon representation. set cartoon_oval_length , 0.8 # default is 1.2
