Abstract Shapes Representation of Secondary Structures

Functions

char *vrna_abstract_shapes(const char *structure, unsigned int level)
#include <ViennaRNA/utils/structures.h>

Convert a secondary structure in dot-bracket notation to its abstract shapes representation.

This function converts a secondary structure into its abstract shapes representation as presented by Giegerich et al. [2004] .

SWIG Wrapper Notes:

This function is available as an overloaded function abstract_shapes() where the optional second parameter level defaults to 5. See, e.g. RNA.abstract_shapes() in the Python API.

Parameters:
  • structure – A secondary structure in dot-bracket notation

  • level – The abstraction level (integer in the range of 0 to 5)

Returns:

The secondary structure in abstract shapes notation

char *vrna_abstract_shapes_pt(const short *pt, unsigned int level)
#include <ViennaRNA/utils/structures.h>

Convert a secondary structure to its abstract shapes representation.

This function converts a secondary structure into its abstract shapes representation as presented by Giegerich et al. [2004] . This function is equivalent to vrna_db_to_shapes(), but requires a pair table input instead of a dot-bracket structure.

SWIG Wrapper Notes:

This function is available as an overloaded function abstract_shapes() where the optional second parameter level defaults to 5. See, e.g. RNA.abstract_shapes() in the Python API.

Note

The length of the structure must be present at pt[0]!

Parameters:
  • pt – A secondary structure in pair table format

  • level – The abstraction level (integer in the range of 0 to 5)

Returns:

The secondary structure in abstract shapes notation
