# Bio::Sequence

# DESCRIPTION

Bio::Sequence objects represent annotated sequences in bioruby. A Bio::Sequence object is a wrapper around the actual sequence, represented as either a Bio::Sequence::NA or a Bio::Sequence::AA object. For most users, this encapsulation will be completely transparent. Bio::Sequence responds to all methods defined for Bio::Sequence::NA/AA objects using the same arguments and returning the same values (even though these methods are not documented specifically for Bio::Sequence).

# USAGE

    # Create a nucleic or amino acid sequence
    dna = Bio::Sequence.auto('atgcatgcATGCATGCAAAA')
    rna = Bio::Sequence.auto('augcaugcaugcaugcaaaa')
    aa = Bio::Sequence.auto('ACDEFGHIKLMNPQRSTVWYU')

    # Print it out
    puts dna.to_s
    puts aa.to_s

    # Get a subsequence, bioinformatics style (first nucleotide is '1')
    puts dna.subseq(2,6)

    # Get a subsequence, informatics style (first nucleotide is '0')
    puts dna[2,6]

    # Print in FASTA format
    puts dna.output(:fasta)

    # Print all codons
    dna.window_search(3,3) do |codon|
      puts codon
    end

    # Splice or otherwise mangle your sequence
    puts dna.splicing("complement(join(1..5,16..20))")
    puts rna.splicing("complement(join(1..5,16..20))")

    # Convert a sequence containing ambiguity codes into a
    # regular expression you can use for subsequent searching
    puts aa.to_re

    # These should speak for themselves
    puts dna.complement
    puts dna.composition
    puts dna.molecular_weight
    puts dna.translate
    puts dna.gc_percent

### Public Class Methods

adapter(source_data, adapter_module) click to toggle source

Normally, users should not call this method directly. Use Bio::*to_biosequence (e.g. Bio::GenBank#to_biosequence).

Creates a new Bio::Sequence object from database data with an adapter module.

    # File lib/bio/sequence.rb, line 463
    def self.adapter(source_data, adapter_module)
      biosequence = self.new(nil)
      biosequence.instance_eval {
        remove_instance_variable(:@seq)
        @source_data = source_data
      }
      biosequence.extend(adapter_module)
      biosequence
    end

auto(str) click to toggle source

Given a sequence String, guess its type, Amino Acid or Nucleic Acid, and return a new Bio::Sequence object wrapping a sequence of the guessed type (either Bio::Sequence::AA or Bio::Sequence::NA)

    s = Bio::Sequence.auto('atgc')
    puts s.seq.class                        #=> Bio::Sequence::NA

Arguments:

- (required) str: String or Bio::Sequence::NA/AA object

Returns | Bio::Sequence object

    # File lib/bio/sequence.rb, line 283
    def self.auto(str)
      seq = self.new(str)
      seq.auto
      return seq
    end

guess(str, *args) click to toggle source

Guess the class of a given sequence. Returns the class (Bio::Sequence::AA or Bio::Sequence::NA) guessed. In general, used by developers only, but if you know what you are doing, feel free.

    puts .guess('atgc')        #=> Bio::Sequence::NA

There are three optional parameters: `threshold`, `length`, and `index`.

The `threshold` value (defaults to 0.9) is the frequency of nucleic acid bases [AGCTUagctu] required in the sequence for this method to produce a Bio::Sequence::NA "guess". In the default case, if less than 90% of the bases (after excluding [Nn]) are in the set [AGCTUagctu], then the guess is Bio::Sequence::AA.

    puts Bio::Sequence.guess('atgcatgcqq')      #=> Bio::Sequence::AA
    puts Bio::Sequence.guess('atgcatgcqq', 0.8) #=> Bio::Sequence::AA
    puts Bio::Sequence.guess('atgcatgcqq', 0.7) #=> Bio::Sequence::NA

The `length` value is how much of the total sequence to use in the guess (default 10000). If your sequence is very long, you may want to use a smaller amount to reduce the computational burden.

    # limit the guess to the first 1000 positions
    puts Bio::Sequence.guess('A VERY LONG SEQUENCE', 0.9, 1000)

The `index` value is where to start the guess. Perhaps you know there are a lot of gaps at the start...

    puts Bio::Sequence.guess('-----atgcc')             #=> Bio::Sequence::AA
    puts Bio::Sequence.guess('-----atgcc',0.9,10000,5) #=> Bio::Sequence::NA

Arguments:

- (required) str: String or Bio::Sequence::NA/AA object

- (optional) threshold: Float in range 0,1 (default 0.9)

- (optional) length: Fixnum (default 10000)

- (optional) index: Fixnum (default 1)

Returns | Bio::Sequence::NA/AA

    def self.guess(str, *args)
      self.new(str).guess(*args)
    end

input(str, format = nil) click to toggle source

Create a new Bio::Sequence object from a formatted string (GenBank, EMBL, fasta format, etc.)

    s = Bio::Sequence.input(str)

Arguments:

- (required) str: string

- (optional) format: format specification (class or nil)

Returns | Bio::Sequence object

    # File lib/bio/sequence.rb, line 436
    def self.input(str, format = nil)
      if format then
        klass = format
      else
        klass = Bio::FlatFile::AutoDetect.default.autodetect(str)
      end
      obj = klass.new(str)
      obj.to_biosequence
    end

new(str) click to toggle source

Create a new Bio::Sequence object

    s = Bio::Sequence.new('atgc')
    puts s                                  #=> 'atgc'

Note that this method does not intialize the contained sequence as any kind of bioruby object, only as a simple string

    puts s.seq.class                        #=> String

See Bio::Sequence#na, Bio::Sequence#aa, and Bio::Sequence#auto for methods to transform the basic String of a just created Bio::Sequence object to a proper bioruby object

Arguments:

- (required) str: String or Bio::Sequence::NA/AA object

Returns | Bio::Sequence object

    # File lib/bio/sequence.rb, line 99
    def initialize(str)
      @seq = str
    end

### Public Instance Methods

aa() click to toggle source

Transform the sequence wrapped in the current Bio::Sequence object into a Bio::Sequence::NA object. This method will change the current object. This method does not validate your choice, so be careful!

    s = Bio::Sequence.new('atgc')
    puts s.seq.class                        #=> String
    s.aa
    puts s.seq.class                        #=> Bio::Sequence::AA !!!

However, if you know your sequence type, this method may be constructively used after initialization,

    s = Bio::Sequence.new('RRLE')
    s.aa

Returns | Bio::Sequence::AA

    # File lib/bio/sequence.rb, line 422
    def aa
      @seq = AA.new(seq)
      @moltype = AA
    end

accessions() click to toggle source

accession numbers of the sequence

Returns | Array of String

    # File lib/bio/sequence.rb, line 454
    def accessions
      [ primary_accession, secondary_accessions ].flatten.compact
    end

auto() click to toggle source

Guess the type of sequence, Amino Acid or Nucleic Acid, and create a new sequence object (Bio::Sequence::AA or Bio::Sequence::NA) on the basis of this guess. This method will change the current Bio::Sequence object.

    s = Bio::Sequence.new('atgc')
    puts s.seq.class                        #=> String
    s.auto
    puts s.seq.class                        #=> Bio::Sequence::NA

Returns | Bio::Sequence::NA/AA object

    # File lib/bio/sequence.rb, line 264
    def auto
      @moltype = guess
      if @moltype == NA
        @seq = NA.new(seq)
      else

      end
    end

guess(threshold = 0.9, length = 10000, index = 0) click to toggle source

Guess the class of the current sequence. Returns the class (Bio::Sequence::AA or Bio::Sequence::NA) guessed. In general, used by developers only, but if you know what you are doing, feel free.

    s = Bio::Sequence.new('atgc')
    puts s.guess                            #=> Bio::Sequence::NA

There are three parameters: `threshold`, `length`, and `index`.

The `threshold` value (defaults to 0.9) is the frequency of nucleic acid bases [AGCTUagctu] required in the sequence for this method to produce a Bio::Sequence::NA "guess". In the default case, if less than 90% of the bases (after excluding [Nn]) are in the set [AGCTUagctu], then the guess is Bio::Sequence::AA.
