NAME
       RNA2Dfold - manual page for RNA2Dfold 2.4.14

SYNOPSIS
       RNA2Dfold [OPTIONS]...

DESCRIPTION
       RNA2Dfold 2.4.14

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

       The program  partitions	the  secondary	structure  space  into	(base-
       pair)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,	Boltz-
       mann probabilities and Gibbs free energy	is computed.  Additionally,  a
       stochastic backtracking routine allows one to produce samples of	repre-
       sentative suboptimal secondary structures from each partition

       -h, --help
	      Print help and exit

       --detailed-help
	      Print help, including all	details	and hidden options, and	exit

       -V, --version
	      Print version and	exit

   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	appro-
	      priate 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 dis-
	      tance 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 dis-
	      tance 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 de-
	      fault parameter set.

	      Different	sets of	energy parameters for RNA and DNA  should  ac-
	      company your distribution.  See the RNAlib documentation for de-
	      tails 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  he-
	      lices 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  de-
	      bugging).

       --noGU Do not allow GU pairs

	      (default=off)

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

	      (default=off)
