Bio::Tools::Run::Promoterwise

NAME

Bio::Tools::Run::Promoterwise - Wrapper for aligning two sequences using promoterwise

SYNOPSIS

# Build a Promoterwise alignment factory
my @params = ('-s'=>1,'-query_start'=>10,'-dymem'=>1);
my $factory = Bio::Tools::Run::Promoterwise->new(@params);
my (@fp)= $factory->run($seq1,$seq2);
# each feature pair is a group of hsps
foreach my $fp(@fp){
print "Hit Length: ".$fp->feature1->length."\n";
print "Hit Start: ".$fp->feature1->start."\n";
print "Hit End: ".$fp->feature1->end."\n";
print "Hsps: \n";
my @first_hsp = $fp->feature1->sub_SeqFeature;
my @second_hsp = $fp->feature2->sub_SeqFeature;
for ($i..$#first_hsp){
print $first_hsp[$i]->seq." ".$second_hsp[$i]->seq."\n";
}
}
print "end: ". $fp->feature2->start."\t".$fp->feature2->end."\n";
#Available parameters include:

#For an explanation of these parameters, please see documentation

DESCRIPTION

Promoterwise is an alignment algorithm that relaxes the constraint that local alignments have to be co-linear. Otherwise it provides a similar model to DBA, which is designed for promoter sequence alignments by Ewan Birney. It is part of the wise2 package available at: http://www.sanger.ac.uk/software/wise2.

FEEDBACK

Mailing Lists
User feedback is an integral part of the evolution of this and other Bioperl modules. Send your comments and suggestions preferably to one of the Bioperl mailing lists. Your participation is much appreciated.

Support
Please direct usage questions or support issues to the mailing list:

bioperl-l AT bioperl DOT org

rather than to the module maintainer directly. Many experienced and reponsive experts will be able look at the problem and quickly address it. Please include a thorough description of the problem with code and data examples if at all possible.

Reporting Bugs

APPENDIX

The rest of the documentation details each of the object methods. Internal methods are usually preceded with a _

program_name
Title : program_name
Usage : $factory>program_name()
Function: holds the program name
Returns: string
Args : None

program_dir
Title : program_dir
Usage : $factory->program_dir(@params)
Function: returns the program directory, obtained from ENV variable.
Returns: string
Args :

version
Title : version
Usage : exit if $prog->version() < 1.8
Function: Determine the version number of the program
Example :
Returns : float or undef
Args : none

run
Title : run
Usage : 2 sequence objects
@fp = $factory->run($seq1, $seq2);
Function: run
Returns : An array of <Bio::SeqFeature::FeaturePair>
Args : Name of a file containing a set of 2 fasta sequences
or else 2 Bio::Seq objects.

Throws an exception if argument is not either a string (eg a filename) or 2 Bio::Seq objects. If arguments are strings, throws exception if file corresponding to string name can not be found.

_run
Title : _run
Usage : Internal function, not to be called directly
Function: makes actual system call to a promoterwise program
Example :
Returns : L<Bio::SeqFeature::FeaturePair>
Args : Name of a files containing 2 sequences in the order of peptide and genomic

_setparams
Title : _setparams
Usage : Internal function, not to be called directly
Function: creates a string of params to be used in the command string
Example :
Returns : string of params
Args :

_query_pep_seq
Title : _query_pep_seq
Usage : Internal function, not to be called directly
Function: get/set for the query sequence
Example :
Returns :
Args :

_subject_dna_seq
Title : _subject_dna_seq
Usage : Internal function, not to be called directly
Function: get/set for the subject sequence
Example :
Returns :
Args :
