RNAHEAT(1)

NAME
RNAheat - manual page for RNAheat 2.3.3

SYNOPSIS
RNAheat [options]

DESCRIPTION
RNAheat 2.3.3

calculate specific heat of RNAs

Reads RNA sequences from stdin and calculates their specific heat in the temperature range t1 to t2, from the partition function by numeric differentiation. The result is written to stdout as a list of pairs of temperature in C and specific heat in Kcal/(Mol*K). The program will continue to read new sequences until a line consisting of the single character "@" or an end of file condition is encountered.

-h, --help
    Print help and exit

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

--full-help
    Print help, including 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

--Tmin=t1
    Lowest temperature

    (default=`0')

--Tmax=t2
    Highest temperature

    (default=`100')

--stepsize=FLOAT
    Calculate partition function every stepsize degrees C

    (default=`1.')

-m, --ipoints=ipoints
    The program fits a parabola to 2*ipoints+1 data points to calculate 2nd derivatives. Increasing this parameter produces a smoother curve

    (default=`2')

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

    (default=off)

  Model Details:

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

    (default=off)

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

    (default=`2')

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

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

--noLP
    Produce structures without lonely pairs (helices of length 1).

    (default=off)

    For partition function folding this only disallows pairs that can only occur isolated. Other pairs may still occasionally occur as helices of length 1.

--noGU
    Do not allow GU pairs

    (default=off)

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

    (default=off)

-P, --paramFile=paramfile
    Read energy parameters from paramfile, instead of using the default parameter set.

    A sample parameter file should accompany your distribution. See the RNAlib documentation for details on the file format.

--nsp=STRING
    Allow other pairs in addition to the usual AU,GC,and GU pairs.

    Its argument is a comma separated list of additionally allowed pairs. If the first character is a "-" then AB will imply that AB and BA are allowed pairs. e.g. RNAfold -nsp -GA will allow GA and AG pairs. Nonstandard pairs are given 0 stacking energy.

-e, --energyModel=INT
    Rarely used option to fold sequences from the artificial ABCD... alphabet, where A pairs B, C-D etc. Use the energy parameters for GC (-e 1) or AU (-e 2) pairs.
