This script adds the dssr_block command, which is a simple wrapper for the DSSR program and can create "block" shaped cartoons for nucleic acid bases and base pairs.
Requires the x3dna-dssr executable, obtainable from http://x3dna.org
Instead of installing x3dna-dssr and the plugin locally, you can also use the web server at http://skmatic.x3dna.org/

Recommended Setup
Place the x3dna-dssr executable into $PATH. Examples:
- Linux/Mac: /usr/bin/x3dna-dssr
- Windows: C:\Program Files\PyMOL\PyMOL\x3dna-dssr.exe
The script can be run, imported as a Python module, or installed with the Plugin Manager.
Usage
dssr_block [ selection [, state [, block_file [, block_depth
[, block_color [, name [, exe ]]]]]]]
Arguments
- selection = str: atom selection {default: all}
- state = int: object state (0 for all states) {default: -1, current state}
- block_file = face|edge|wc|equal|minor|gray: Corresponds to the --block-file option (see DSSR manual). Values can be combined, e.g. "wc-minor". {default: face}
- block_depth = float: thickness of rectangular blocks {default: 0.5}
- block_color = str: Corresponds to the --block-color option (new in DSSR v1.5.2) {default: }
- name = str: name of new CGO object {default: dssr_block##}
- exe = str: path to "x3dna-dssr" executable {default: x3dna-dssr}
Examples
Combining DSSR block representation with regular PyMOL cartoons:
fetch 1ehz, async=0
as cartoon
set cartoon_ladder_radius, 0.1
set cartoon_ladder_color, gray
set cartoon_nucleic_acid_mode, 1
dssr_block
Joined base-pair blocks (block_file=wc):
fetch 1ehz, async=0
dssr_block block_file=wc
Multi-state Example:
fetch 2n2d, async=0
dssr_block 2n2d, 0
set all_states
Custom coloring:
fetch 1msy, async=0
dssr_block block_color=N red | minor 0.9 | major yellow
