NAME

       RNA2Dfold - manual page for RNA2Dfold 2.5.1

SYNOPSIS

       RNA2Dfold [OPTION]...

DESCRIPTION

       RNA2Dfold 2.5.1

       Compute  MFE  structure,  partition  function  and representative sample structures of k,l
       neighborhoods

       The program partitions the  secondary  structure  space  into  (basepair)distance  classes
       according  to  two  fixed  reference  structures.  It expects a sequence and two secondary
       structures in dot-bracket notation as  its  inputs.  For  each  distance  class,  the  MFE
       representative, Boltzmann probabilities and Gibbs free energy is computed. Additionally, a
       stochastic backtracking routine allows one to produce samples of representative suboptimal
       secondary structures from each partition

   General Options:
              Below are command line options which alter the general behavior of this program

       --noconv
              Do not automatically substitude nucleotide "T" with "U"

              (default=off)

       -j, --numThreads=INT
              Set  the number of threads used for calculations (only available when compiled with
              OpenMP support)

   Algorithms:
       -p, --partfunc
              calculate partition function and  thus,  Boltzmann  probabilities  and  Gibbs  free
              energy

              (default=off)

       --stochBT=INT
              backtrack   a  certain  number  of  Boltzmann  samples  from  the  appropriate  k,l
              neighborhood(s)

       --neighborhood=<k>:<l>
              backtrack structures from certain k,l-neighborhood only, can be specified  multiple
              times (<k>:<l>,<m>:<n>,...)

       -S, --pfScale=DOUBLE
              scaling factor for pf to avoid overflows

       --noBT do not backtrack structures, calculate energy contributions only

              (default=off)

       -c, --circ
              Assume a circular (instead of linear) RNA molecule.

              (default=off)

   Model Details:
       -T, --temp=DOUBLE
              Rescale energy parameters to a temperature of temp C. Default is 37C.

       -K, --maxDist1=INT
              maximum distance to first reference structure

              If  this  value is set all structures that exhibit a basepair distance greater than
              maxDist1 will be thrown into a distance class denoted by K=L=-1

       -L, --maxDist2=INT
              maximum distance to second reference structure

              If this value is set all structures that exhibit a basepair distance  greater  than
              maxDist1 will be thrown into a distance class denoted by K=L=-1

       -4, --noTetra
              Do not include special tabulated stabilizing energies for tri-, tetra- and hexaloop
              hairpins. Mostly for testing.

              (default=off)

       -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 an input file.

       -d, --dangles=INT
              How to treat "dangling end" energies for bases adjacent to helices in free ends and
              multi-loops

              (possible values="0", "2" default=`2')

              With -d2 dangling energies will be added for the bases adjacent to a helix on  both
              sides

              in any case.

              The option -d0 ignores dangling ends altogether (mostly for debugging).

       --noGU Do not allow GU pairs

              (default=off)

       --noClosingGU
              Do not allow GU pairs at the end of helices

              (default=off)
