## Function Documentation

float vrna_eval_structure | ( | vrna_fold_compound_t * | vc,
|  | const char * | structure
| ) |  |

Calculate the free energy of an already folded RNA.

This function allows for energy evaluation of a given pair of structure and sequence (alignment). Model details, energy parameters, and possibly soft constraints are used as provided via the parameter 'vc'. The vrna_fold_compound_t does not need to contain any DP matrices, but requires all most basic init values as one would get from a call like this:

vc = vrna_fold_compound(sequence, NULL, VRNA_OPTION_EVAL_ONLY);

Note
  Accepts vrna_fold_compound_t of type VRNA_VC_TYPE_SINGLE and VRNA_VC_TYPE_ALIGNMENT

See also
  vrna_eval_structure_pt(), vrna_eval_structure_verbose(), vrna_eval_structure_pt_verbose(), vrna_fold_compound(), vrna_fold_compound_comparative(), vrna_eval_covar_structure()

Parameters

  vc | A vrna_fold_compound_t containing the energy parameters and model details
  structure | Secondary structure in dot-bracket notation

Returns
  The free energy of the input structure given the input sequence in kcal/mol

float vrna_eval_covar_structure | ( | vrna_fold_compound_t * | vc,
|  | const char * | structure
| ) |  |

Calculate the pseudo energy derived by the covariance scores of a set of aligned sequences.

Consensus structure prediction is driven by covariance scores of base pairs in rows of the provided alignment. This function allows to retrieve the total amount of this covariance pseudo energy scores. The vrna_fold_compound_t does not need to contain any DP matrices, but requires all most basic init values as one would get from a call like this:

vc = vrna_fold_compound_comparative(alignment, NULL, VRNA_OPTION_EVAL_ONLY);

Note
  Accepts vrna_fold_compound_t of type VRNA_VC_TYPE_ALIGNMENT only!

See also
  vrna_fold_compound_comparative(), vrna_eval_structure()

Parameters

  vc | A vrna_fold_compound_t containing the energy parameters and model details
  structure | Secondary (consensus) structure in dot-bracket notation

Returns
  The covariance pseudo energy score of the input structure given the input sequence alignment in kcal/mol

float vrna_eval_structure_simple | ( | const char * | string,
|  | const char * | structure
| ) |  |

Calculate the free energy of an already folded RNA.

This function allows for energy evaluation of a given sequence/structure pair. In contrast to vrna_eval_structure() this function assumes default model details and default energy parameters in order to evaluate the free energy of the secondary structure. Therefore, it serves as a simple interface function for energy evaluation for situations where no changes on the energy model are required.

See also
  vrna_eval_structure(), vrna_eval_structure_pt(), vrna_eval_structure_verbose(), vrna_eval_structure_pt_verbose(),

Parameters

  string | RNA sequence in uppercase letters
  structure | Secondary structure in dot-bracket notation

Returns
  The free energy of the input structure given the input sequence in kcal/mol

float vrna_eval_structure_verbose | ( | vrna_fold_compound_t * | vc,
|  | const char * | structure,
|  | FILE * | file
| ) |  |

Calculate the free energy of an already folded RNA and print contributions on a per-loop base.

This function is a simplyfied version of vrna_eval_structure_v() that uses the default verbosity level. (

See also
  vrna_eval_structure_pt(), vrna_eval_structure_verbose(), vrna_eval_structure_pt_verbose(),

Parameters

  vc | A vrna_fold_compound_t containing the energy parameters and model details
  structure | Secondary structure in dot-bracket notation
  file | A file handle where this function should print to (may be NULL).

Returns
  The free energy of the input structure given the input sequence in kcal/mol

float vrna_eval_structure_v | ( | vrna_fold_compound_t * | vc,
|  | const char * | structure,
|  | int | verbosity_level,
|  | FILE * | file
| ) |  |

Calculate the free energy of an already folded RNA and print contributions on a per-loop base.

This function allows for detailed energy evaluation of a given sequence/structure pair. In contrast to vrna_eval_structure() this function prints detailed energy contributions based on individual loops to a file handle. If NULL is passed as file handle, this function defaults to print to stdout. Any positive `verbosity_level` activates potential warning message of the energy evaluting functions, while values allow for detailed control of what data is printed. A negative parameter `verbosity_level` turns off printing all together.

Model details, energy parameters, and possibly soft constraints are used as provided via the parameter 'vc'. The fold_compound does not need to contain any DP matrices, but all the most basic init values as one would get from a call like this:

vc = vrna_fold_compound(sequence, NULL, VRNA_OPTION_EVAL_ONLY);
