## Function Documentation

int PS_rna_plot | ( | char * | string,
|  | char * | structure,
|  | char * | file |
| ) |  |  |

Produce a secondary structure graph in PostScript and write it to 'filename'.

Note that this function has changed from previous versions and now expects the structure to be plotted in dot-bracket notation as an argument. It does not make use of the global base_pair array anymore.

Parameters:

    | string | The RNA sequence Parameters:
      | structure | The secondary structure in dot-bracket notation Parameters:
      | file | The filename of the postscript output Returns: 1 on success, 0 otherwise

int PS_rna_plot_a | ( | char * | string,
|  | char * | structure,
|  | char * | file,
|  | char * | pre,
|  | char * | post |
| ) |  |  |

Produce a secondary structure graph in PostScript including additional annotation macros and write it to 'filename'.

Same as PS_rna_plot() but adds extra PostScript macros for various annotations (see generated PS code). The 'pre' and 'post' variables contain PostScript code that is verbatim copied in the resulting PS file just before and after the structure plot. If both arguments ('pre' and 'post') are NULL, no additional macros will be printed into the PostScript.

Parameters:

    | string | The RNA sequence Parameters:
      | structure | The secondary structure in dot-bracket notation Parameters:
        | file | The filename of the postscript output Parameters:
          | pre | PostScript code to appear before the secondary structure plot Parameters:
          | post | PostScript code to appear after the secondary structure plot Returns: 1 on success, 0 otherwise

int gmlRNA | ( | char * | string,
|  | char * | structure,
|  | char * | ssfile,
|  | char | option |
| ) |  |  |

Produce a secondary structure graph in Graph Meta Language (gml) and write it to a file.

If 'option' is an uppercase letter the RNA sequence is used to label nodes, if 'option' equals 'X' or 'x' the resulting file will coordinates for an initial layout of the graph.

Parameters:

    | string | The RNA sequence Parameters:
      | structure | The secondary structure in dot-bracket notation Parameters:
        | ssfile | The filename of the gml output Parameters:
        | option | The option flag Returns: 1 on success, 0 otherwise

int ssv_rna_plot | ( | char * | string,
|  | char * | structure,
|  | char * | ssfile |
| ) |  |  |

Produce a secondary structure graph in SStructView format.

Write coord file for SStructView

Parameters:

    | string | The RNA sequence Parameters:
      | structure | The secondary structure in dot-bracket notation Parameters:
      | ssfile | The filename of the ssv output Returns: 1 on success, 0 otherwise

int svg_rna_plot | ( | char * | string,
|  | char * | structure,
|  | char * | ssfile |
| ) |  |  |

Produce a secondary structure plot in SVG format and write it to a file.

Parameters:

    | string | The RNA sequence Parameters:
      | structure | The secondary structure in dot-bracket notation Parameters:
      | ssfile | The filename of the svg output Returns: 1 on success, 0 otherwise

int xrna_plot | ( | char * | string,
|  | char * | structure,
|  | char * | ssfile |
| ) |  |  |

Produce a secondary structure plot for further editing in XRNA.

Parameters:

    | string | The RNA sequence Parameters:
      | structure | The secondary structure in dot-bracket notation Parameters:
      | ssfile | The filename of the xrna output Returns: 1 on success, 0 otherwise

int PS_dot_plot_list | ( | char * | seq,
|  | char * | filename,
|  | plist * | pl,
|  | plist * | mf,
|  | char * | comment |
| ) |  |  |

Produce a postscript dot-plot from two pair lists.

This function reads two plist structures (e.g. base pair probabilities and a secondary structure) as produced by assign_plist_from_pr() and assign_plist_from_db() and produces a postscript "dot plot" that is written to 'filename'.
Using base pair probabilities in the first and mfe structure in the second plist, the resulting "dot plot" represents each base pairing probability by a square of corresponding area in a upper triangle matrix. The lower part of the matrix contains the minimum free energy structure.

See also:
  assign_plist_from_pr(), assign_plist_from_db()

Parameters:

    | seq | The RNA sequence Parameters:
      | filename | A filename for the postscript output Parameters:
        | pl | The base pair probability pairlist Parameters:
          | mf | The mfe secondary structure pairlist Parameters:
          | comment | A comment Returns: 1 if postscript was successfully written, 0 otherwise

int PS_dot_plot | ( | char * | string,
|  | char * | file |
| ) |  |  |

Wrapper to PS_dot_plot_list.

Produce postscript dot-plot Reads base pair probabilities produced by pf_fold() from the global array pr and the pair list base_pair produced by fold() and produces a postscript "dot plot" that is written to 'filename'. The "dot plot" represents each base pairing probability by a square of corresponding area in a upper triangle matrix. The lower part of the matrix contains the minimum free energy
