NAME

RNA::HairpinFigure - Draw hairpin-like text figure from RNA sequence and its secondary structure in dot-bracket notation.

DESCRIPTION

miRNA database miRBase maintains miRNAs and their precursors -- pre-miRNAs which have hairpin-like secondary structures. They provide the hairpin-like text figure along with sequences and secondary structures in dot-bracket notation which could produced by ViennaRNA package.

However, neigher miRBase nor ViennaRNA provide any scripts or programs to transfrom dot-bracket notation to hairpin-like text figure, which was needed in our miRNA prediction project.

RNA::HairpinFigure draws hairpin-like text figure from RNA sequence and its secondary structure in dot-bracket notation. If the hairpin have multi loops, they will be deleted and treated as a big loop, the longest stem will be the final stem.

This module is part of the FOMmiR miRNA predictor on http://bioinf.shenwei.me or http://bioinf.xnyy.cn/.

May this module be helpful for you.

VERSION

Version 0.13 released in 2013.

SYNOPSIS

Usage:

use RNA::HairpinFigure qw/draw/;

my $name   = 'hsa-mir-92a-1 MI0000093 Homo sapiens miR-92a-1 stem-loop';
my $seq    = 'CUUUCUACACAGGUUGGGAUCGGUUGCAAUGCUGUGUUUCUGUAUGGUAUUGCACUUGUCCCGGCCUGUUGAGUUUGG';
my $struct = '..(((...((((((((((((.(((.(((((((((((......)))))))))))))).)))))))))))).))).....';
   
my $figure = draw( $seq, $struct );

print ">$name\n$seq\n$struct\n$figure\n";

Output:

SUBROUTINES/METHODS

Draw SCALAR SCALAR

Returns the hairpin-like text figures. Sequence and its secondary structure in dot-bracket notation are both required as arguments.

When a hairpin has multi-loops, only the longest stem remains according to miRBase's practice.

make_pair_table SCALAR

Returns hash reference which represent the dot-bracket notation. Table{i} is j if (i, j) pair.

Secondary structure in dot-bracket notation is required.

make_pair_table_deleting_multi_loops SCALAR

It makes pair table for dot-bracket notation with multi loops, which will be deleted and treated as a big loop, the longest stem will be the final stem.

Returns hash reference which represent the dot-bracket notation. Table{i} is j if (i, j) pair.

Secondary structure in dot-bracket notation is required.
