NAME

GeneDesign::PrefixTree - A suffix tree implementation for nucleotide searching

VERSION

Version 5.56

DESCRIPTION

GeneDesign uses this object to parse peptide sequences for restriction enzyme
recognition site possibilities

AUTHOR

Sarah Richardson <SMRichardson@lbl.gov>

Functions

new

Create a new suffix tree object.

my $tree = Bio::GeneDesign::PrefixTree->new();

add_prefix

Add suffixes to the tree. You can add a sequence, an id (which can be an array reference of ids), and a scalar note.

$tree->add_prefix('GGATCC', 'BamHI', "i hope this didn't pop up");
$tree->add_prefix('GGCCC', ['OhnoI', 'WoopsII'], "I hope these pop up");

find_prefixes()

Pass a sequence to the tree and find the positions of hits. It will return an array that is made up of array references; each array reference represents a hit where the 0 index is the name of the subsequence in the tree, the 1 index is the offset in the query sequence (1 BASED, NOT 0 BASED), the 2 index is the subsequence, and the 3 index is whatever note is associated with the subsequence.

my @hits = $tree->find_prefixes('AAAGGATCCATCGCATACGAGGCCCCACCG');

# @hits = (['BamHI', 4, 'GGATCC', 'i hope this didn't pop up'],
#          ['OhnoI', 21, 'GGCCC', 'I hope these pop up'],
#          ['WoopsII', 21, 'GGCCC', 'I hope these pop up']
#);

find_ntons

Pass a number, n. The tree will report all of the sequences inside it that it has only seen n times. The return value is a hash, where the keys are the sequences and the values are hash references containing the ids and notes associated with each sequence in the tree.

my %twos = $tree->find_ntons(2);

# %twos = ('GGGCC' => {'OhnoI' => ['I hope these pop up'],
#                    'WoopsII' => ['I hope these pop up']}
# );
