Internal methods are usually preceded with a _

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
