NAME ^

Bio::SeqFeature::SiRNA::Pair - Perl object for small inhibitory RNA (SiRNA) oligo pairs

SYNOPSIS ^

  use Bio::SeqFeature::SiRNA::Pair;
  my $pair = Bio::SeqFeature::SiRNA::Pair->
      new( -sense       => $bio_seqfeature_sirna_oligo, # strand=1
           -antisense   => $bio_seqfeature_sirna_oligo, # strand= -1
           -primary     => 'SiRNA::Pair',
           -source_tag  => 'Bio::Tools::SiRNA',
           -start       => 8,
           -end         => 31,
           -rank        => 1,
           -fxgc        => 0.5,
           -tag         => { note => 'a note' } );

  $target_sequence->add_SeqFeature($pair);

DESCRIPTION ^

Object methods for (complementary) pairs of Bio::SeqFeature::SiRNA::Oligo objects - inherits Bio::SeqFeature::Generic. See that package for information on inherited methods.

Does not include methods for designing SiRNAs -- see Bio::Tools::SiRNA

SEE ALSO ^

Bio::SeqFeature::Oligo, Bio::Tools::SiRNA.

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 the Bioperl mailing list. Your participation is much appreciated.

Support

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

bioperl-l@bioperl.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

Report bugs to the Bioperl bug tracking system to help us keep track of the bugs and their resolution. Bug reports can be submitted via the web:

METHODS ^

new

  Title         : new
  Usage         : my $sirna_pair = Bio::SeqFeature::SiRNA::Pair->new();
  Purpose       : Create a new SiRNA::Pair object
  Returns       : Bio::Tools::SiRNA object
  Args          : -start        10
                  -end          31
                  -rank         1 #  'Rank' in Tuschl group's rules
                  -fxgc         0.5 # GC fraction for target sequence
                  -primary      'SiRNA::Pair', # default value
                  -source_tag   'Bio::Tools::SiRNA'
                  -tag          { note => 'A note' }
                  -sense        a Bio::SeqFeature::SiRNA::Oligo object
                                with strand = 1
                  -antisense    a Bio::SeqFeature::SiRNA::Oligo object
                                with strand = -1
);

  Note          : SiRNA::Pair objects are typically created by a design 
                  algorithm such as Bio::Tools::SiRNA

rank

  Title         : rank
  Usage         : my $pair_rank = $sirna_pair->rank()
  Purpose       : Get/set the 'quality rank' for this pair.
                  See Bio::Tools::SiRNA for a description of ranks.
  Returns       : scalar
  Args          : scalar (optional) indicating pair rank

fxGC

  Title         : fxGC
  Usage         : my $fxGC = $sirna_pair->fxGC();
  Purpose       : Get/set the fraction of GC for this pair - based on TARGET sequence, not oligos.
  Returns       : scalar between 0-1
  Args          : scalar between 0-1 (optional)

sense

  Title         : sense
  Usage         : my $sense_oligo = $sirna_pair->sense()
  Purpose       : Get/set the SiRNA::Oligo object corresponding to the sense strand
  Returns       : Bio::SeqFeature::SiRNA::Oligo object
  Args          : Bio::SeqFeature::SiRNA::Oligo object

antisense

  Title         : antisense
  Usage         : my $antisense_oligo = $sirna_pair->antisense()
  Purpose       : Get/set the SiRNA::Oligo object corresponding to the antisense strand
  Returns       : Bio::SeqFeature::SiRNA::Oligo object
  Args          : Bio::SeqFeature::SiRNA::Oligo object
