int E_Stem(int type, int si1, int sj1, int extLoop, vrna_param_t *P)
- #include <ViennaRNA/loops/external.h>
Compute the energy contribution of a stem branching off a loop-region.
This function computes the energy contribution of a stem that branches off a loop region. This can be the case in multiloops, when a stem branching off increases the degree of the loop but also immediately interior base pairs of an exterior loop contribute free energy. To switch the behavior of the function according to the evaluation of a multiloop- or exterior-loop-stem, you pass the flag ‘extLoop’. The returned energy contribution consists of a TerminalAU penalty if the pair type is greater than 2, dangling end contributions of mismatching nucleotides adjacent to the stem if only one of the si1, sj1 parameters is greater than 0 and mismatch energies if both mismatching nucleotides are positive values. Thus, to avoid incorporating dangling end or mismatch energies just pass a negative number, e.g. -1 to the mismatch argument.
This is an illustration of how the energy contribution is assembled:
Here, (X,Y) is the base pair that closes the stem that branches off a loop region. The nucleotides si1 and sj1 are the 5’- and 3’- mismatches, respectively. If the base pair type of (X,Y) is greater than 2 (i.e. an A-U or G-U pair, the TerminalAU penalty will be included in the energy contribution returned. If si1 and sj1 are both nonnegative numbers, mismatch energies will also be included. If one of si1 or sj1 is a negative value, only 5’ or 3’ dangling end contributions are taken into account. To prohibit any of these mismatch contributions to be incorporated, just pass a negative number to both, si1 and sj1. In case the argument extLoop is 0, the returned energy contribution also includes the internal-loop-penalty of a multiloop stem with closing pair type.
- Deprecated:
Please use one of the functions vrna_E_ext_stem() and E_MLstem() instead! Use the former for cases where
extLoop!= 0 and the latter otherwise.

- Parameters

static int E_IntLoop(int n1, int n2, int type, int type_2, int si1, int sj1, int sp1, int sq1, vrna_param_t *P)
- #include <ViennaRNA/loops/internal.h>
Compute the Energy of an interior-loop
This function computes the free energy \(\Delta G\) of an interior-loop with the following structure: This general structure depicts an interior-loop that is closed by the base pair (X,Y). The enclosed base pair is (V,U) which leaves the unpaired bases a_1-a_n and b_1-b_n that constitute the loop. In this example, the length of the interior-loop is \((n+m)\)
where n or m may be 0 resulting in a bulge-loop or base pair stack. The mismatching nucleotides for the closing pair (X,Y) are:
5’-mismatch: a_1
3’-mismatch: b_m
and for the enclosed base pair (V,U):
5’-mismatch: b_1
3’-mismatch: a_n
See also
Note
Base pairs are always denoted in 5’->3’ direction. Thus the enclosed base pair must be ‘turned arround’ when evaluating the free energy of the interior-loop
