NAME

Bio::SeqAlignment::Components::Sundry::Tailing - Add various tails to sequences

VERSION

version 0.01

SYNOPSIS

use Bio::SeqAlignment::Components::Sundry::Tailing;
my $modifications_HoH = add_polyA( $bioseq_objects, $taildist, $seed, @distparams );

DESCRIPTION

This module provides functions to add various tails to the 3' of biological sequences. Such modifications are useful for e.g. simulating polyA tails in RNAseq, adding UMI tags to sequences, etc.

EXPORT

SUBROUTINES

add_polyA

my $modifications_HoH = add_polyA( $bioseq_objects, $taildist, $seed, @distparams );

Add a polyA tail to each sequence in the array of biological sequence objects. The functiontakes a reference to an array of biological sequence objects (e.g. Bio::Seq,BioX::Seq, FAST::Bio::Seq, or anything that provides a seq and id method), a possibly truncated tail distribution from the Gnu Scientific Library, a seed and a list of distribution parameters for the tail distribution. The function modifies the array in situ and returns a reference to a hash of modifications (i.e. the position the polyA tail was added as well as its length. Note that this function uses simulation to generate a tail of random length.
