Cartoon gap cutoff

With cartoon_gap_cutoff > 0, if there are missing residues along the protein backbone (e.g. missing loops), PyMOL will create a dashed cartoon loop segment if the gap (in number of residues) is shorter than the cutoff.

New in PyMOL 1.8.2


set cartoon_gap_cutoff, 10

fetch 2xwu, async=0
as cartoon
orient B//152-156/

Number of dashes

The number of dashes is directly affected by the cartoon_sampling setting:

set cartoon_sampling, 20
