General Options:

Command line options which alter the general behavior of this program

−v, −−verbose

Be verbose.

(default=off)

−s, −−sequence=STRING

The RNA sequence (ACGU)

−e, −−max−energy=INT

Structures are only counted until this threshold is reached. Default is 0 kcal/mol.

(default=‘0’)

−j, −−numThreads=INT

Set the number of threads used for calculations (only available when compiled with OpenMP support)

Model Details:
−T
, −−temp=DOUBLE

Rescale energy parameters to a temperature of temp C. Default is 37C.

−d, −−dangles=INT

How to treat "dangling end" energies for bases adjacent to helices in free ends and multi−loops

(default=‘2’)

With −d1 only unpaired bases can participate in at most one dangling end. With −d2 this check is ignored, dangling energies will be added for the bases adjacent to a helix on both sides in any case; this is the default for mfe and partition function folding (−p). The option −d0 ignores dangling ends altogether (mostly for debugging). With −d3 mfe folding will allow coaxial stacking of adjacent helices in multi−loops. At the moment the implementation will not allow coaxial stacking of the two interior pairs in a loop of degree 3 and works only for mfe folding.

Note that with −d1 and −d3 only the MFE computations will be using this setting while partition function uses −d2 setting, i.e. dangling ends will be treated differently.

−P, −−paramFile=paramfile

Read energy parameters from paramfile, instead of using the default parameter set.

Different sets of energy parameters for RNA and DNA should accompany your distribution. See the RNAlib documentation for details on the file format. When passing the placeholder file name "DNA", DNA parameters are loaded without the need to actually specify any input file.

Advanced options:
−b
, −−hashtable−bits=INT

Set the size of the hash table for each cell in the dp−matrices.

(default=‘20’)
