INTERNAL USE ONLY, YOU SHOULD NOT USE THIS CLASS. Simple Fasta format output class for Bio::Sequence.
INTERNAL USE ONLY, YOU SHOULD NOT CALL THIS METHOD.
Creates a new Fasta format generater object from the sequence.
Arguments:
sequence: Bio::Sequence object
(optional) :header => header: String (default nil)
(optional) :width => width: Fixnum (default 70)
# File lib/bio/db/fasta/format_fasta.rb, line 26 def initialize; end
INTERNAL USE ONLY, YOU SHOULD NOT CALL THIS METHOD.
Output the FASTA format string of the sequence.
Currently, this method is used in Bio::Sequence#output like so,
s = Bio::Sequence.new('atgc') puts s.output(:fasta) #=> "> \natgc\n"
Returns |
String object |
# File lib/bio/db/fasta/format_fasta.rb, line 38 def output header = @options[:header] width = @options.has_key?(:width) ? @options[:width] : 70 seq = @sequence.seq entry_id = @sequence.entry_id || "#{@sequence.primary_accession}.#{@sequence.sequence_version}" definition = @sequence.definition header ||= "#{entry_id} #{definition}" ">#{header}\n" + if width seq.to_s.gsub(Regexp.new(".{1,#{width}}"), "\\0\n") else seq.to_s + "\n" end end
