Lines is name of the basic representation for atoms and bonds in PyMOL. Lines is a very simple representation, where each atom bond is displayed as a single colored line, and each atom is displayed as the intersection of any two or more non-terminal bonds.
# show everything as lines show lines # only show residues 50-80 as lines show lines, i.50-80
Example: Displaying dashed lines between two atoms
The following commands will create a dashed line between two atoms.
# first, create two named selections select a, ///A/501/02 select b, ///B/229/N # calculate & show the distance from selection a to selection b. distance d, a, b # hide just the distance labels; the # dashed bars should still be shown hide labels, d
Technically, the object d is a labelled distance, only the label is hidden. When ray-tracing the image, the dashes come out a bit fat. You can slim them with
set dash_gap, 0.5 set dash_radius, 0.1
before the 'ray' command.
