Default settings
The defaults give a phosphate backbone with single sticks passing across the full width of the base plane.
set cartoon_nucleic_acid_mode, 4 # backbone follows phosphates
set cartoon_ladder_mode, 1 # sticks from backbone into nucleotide
set cartoon_ring_mode, 0 # no nucleotide rings
set cartoon_ring_finder, 1 # ribose and base rings (not displayed since ring mode 0)
Cartoon ring mode
Settings
set cartoon_ring_mode, value
| value | effect |
|---|---|
| 0 | stick from backbone atom to N1 of purines and N3 of pyrimidines |
| 1 | simple plane for ribose and base rings covering area between ring bonds |
| 2 | simple plane for ribose and base rings covering area inside sticks (slightly smaller than mode 1) |
| 3 | plane bounded by sticks for ribose and base rings |
| 4 | large sphere of ring diameter at centre of ribose and each base ring |
| 5 | small sphere of 1/10 diameter at centre of ribose and each base ring |
Examples
Cartoon ring finder
Settings
set cartoon_ring_finder, value
| value | effect |
|---|---|
| 0 | no rings or sticks joining them |
| 1 | both ribose and base ring |
| 2 | only base ring(s), stick connects directly from phosphate to ring |
| 3 | very similar to ring finder 1, slight effect on transparency = distinct behaviour? |
| 4 | very similar to ring finder 1, slight effect on transparency = distinct behaviour? |
| 5 | sticks visible but rings invisible |
Examples
all with: cartoon_ladder_mode,1 cartoon_ring_mode,3 cartoon_nucleic_acid_mode,0
Cartoon ladder mode
Settings
set cartoon_ladder_mode, value
| value | effect |
|---|---|
| 0 | no sticks shown |
| 1 | sticks show |
Examples
all with: cartoon_ring_mode,3 cartoon_nucleic_acid_mode,0 cartoon_ring_finder,1
Note that the visibility of the ladder sticks depends on ring mode >0, ring finder >0, nucleic acid mode = 0
Cartoon nucleic acid mode
Settings
set cartoon_nucleic_acid_mode, value
| value | effect |
|---|---|
| 0 | smooth backbone passing through phosphorus atoms, backbone terminates at last phosphorus on either end of chain |
| 1 | smooth backbone passing through ribose C3' atoms, backbone terminates at last C3' on either end of chain |
| 2 | smooth backbone passing through phosphorus atoms, backbone terminates at last phosphorus on 5' end and O3' on 3' end (note takes O3' colour at terminus in default colouring) |
| 3 | appears same as mode 0? |
| 4 | appears same as mode 2? |
