RNA::HairpinFigure - Draw hairpin-like text figure from RNA sequence and its secondary structure in dot-bracket notation.
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, neither 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 0.141212 released at 12th Dec. 2014.
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:

draw make_pair_table make_pair_table_deleting_multi_loops
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.
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.
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.
