NAME
Mdust - Perl extension for Mdust nucleotide filteringSYNOPSIS
use Bio::Tools::Run::Mdust; my $mdust = Bio::Tools::Run::Mdust->new(); $mdust->run($bio_seq_object);
DESCRIPTION
Perl wrapper for the nucleic acid complexity filtering program mdust as available from TIGR (http://www.tigr.org/tdb/tgi/software/). Takes a bioperl primary seq object of type DNA as input. Returns a Bio::Seq object with the low-complexity regions changed to Ns OR a Bio::Seq::RichSeq object with the low-complexity regions identified as a SeqFeature::Generic with primary tag = 'Excluded'.This module uses the environment variable MDUSTDIR to find the mdust program. Set MDUSTDIR to the directory containing the mdust binary (example: if mdust is installed as /usr/local/bin/mdust, set MDUSTDIR to '/usr/local/bin').

The rest of the documentation details each of the object methods. Internal methods are usually preceded with a _new
Title : new Usage : my $mdust = Bio::Tools::Run::Mdust->new( -target => $target_bioseq) Purpose : Create a new mdust object Returns : A Bio::Seq object Args : target - Bio::Seq object for masking - alphabet MUST be DNA. wsize - word size for masking (default = 3) cutoff - cutoff score for masking (default = 28) maskchar - character for replacing masked regions (default = N) coords - boolean - indicate low-complexity regions as Bio::SeqFeature::Generic objects with primary tag 'Excluded', do not change sequence (default 0) tmpdir - directory for storing temporary files debug - boolean - toggle debugging output, do not remove temporary files Note : All of the arguments can also be get/set with their own accessors, such as: my $wsize = $mdust->wsize();
run
Title : run Usage : $mdust->run(); Purpose : Run mdust on the target sequence Args : target (optional) - Bio::Seq object of alphabet DNA for masking Returns : Bio::Seq object (see 'new' for details)
target
Title : target Usage : $mdust->target($bio_seq) Purpose : Set/get the target (sequence to be filtered). Returns : Target Bio::Seq object Args : Bio::Seq object using the DNA alphabet (optional)
