Method: Bio::Sequence::AA.randomize

Defined in:
lib/bio/sequence/compat.rb

.randomize(*arg, &block) ⇒ Object

Generate a new random sequence with the given frequency of bases. The sequence length is determined by their cumulative sum. (See also Bio::Sequence::Common#randomize which creates a new randomized sequence object using the base composition of an existing sequence instance).

counts = {'R'=>1,'L'=>2,'E'=>3,'A'=>4}
puts Bio::Sequence::AA.randomize(counts)  #=> "AAEAELALRE" (for example)

You may also feed the output of randomize into a block

actual_counts = {'R'=>0,'L'=>0,'E'=>0,'A'=>0}
Bio::Sequence::AA.randomize(counts) {|x| actual_counts[x] += 1}
actual_counts                     #=> {"A"=>4, "L"=>2, "E"=>3, "R"=>1}

Arguments:

  • (optional) hash: Hash object

Returns

Bio::Sequence::AA object
