## Detailed Description

## Function Documentation

float cofold | ( | const char * | sequence,
|  | char * | structure
| ) |  |

Compute the minimum free energy of two interacting RNA molecules.

The code is analog to the fold() function. If cut_point ==-1 results should be the same as with fold().

Parameters:

  sequence | The two sequences concatenated
  structure | Will hold the barcket dot structure of the dimer molecule

Returns:
  minimum free energy of the structure

Export the arrays of partition function cofold (with gquadruplex support)

Export the cofold arrays for use e.g. in the concentration Computations or suboptimal secondary structure backtracking

Parameters:

  f5_p | A pointer to the 'f5' array, i.e. array conatining best free energy in interval [1,j]
  c_p | A pointer to the 'c' array, i.e. array containing best free energy in interval [i,j] given that i pairs with j
  fML_p | A pointer to the 'M' array, i.e. array containing best free energy in interval [i,j] for any multiloop segment with at least one stem
  fM1_p | A pointer to the 'M1' array, i.e. array containing best free energy in interval [i,j] for multiloop segment with exactly one stem
  fc_p | A pointer to the 'fc' array, i.e. array ...
  ggg_p | A pointer to the 'ggg' array, i.e. array containing best free energy of a gquadruplex delimited by [i,j]
  indx_p | A pointer to the indexing array used for accessing the energy matrices
  ptype_p | A pointer to the ptype array containing the base pair types for each possibility (i,j)
