Module: Bio::Alignment::HashExtension

Includes:
EnumerableExtension
Included in:
OriginalAlignment, SequenceHash
Defined in:
lib/bio/alignment.rb

Overview

Bio::Alignment::HashExtension is a set of useful methods for multiple sequence alignment. It is designed to be extended to hash objects or included in your own classes which inherit Hash. (It can also be included in Hash, though not recommended.)

It possesses all methods defined in EnumerableExtension. For usage of methods, please refer to EnumerableExtension.

Because SequenceHash#alignment_collect is redefined, some methods’ return value’s class are changed to SequenceHash instead of SequenceArray.

Because the order of the objects in a hash is inconstant, some methods strictly affected with the order of objects might not work correctly, e.g. EnumerableExtension#convert_match and #convert_unmatch.

Instance Method Details

#alignment_collect ⇒ Object

Iterates over each sequence and each results running block are collected and returns a new alignment as a Bio::Alignment::SequenceHash object.

Note that it would be redefined if you want to change return value’s class.

def alignment_collect
  a = SequenceHash.new
  a.set_all_property(get_all_property)
  each_pair do |key, str|
    a.store(key, yield(str))
  end
  a
end

#alignment_concat(align) ⇒ Object

Concatenates the given alignment. If align is a Hash (or SequenceHash), sequences of same keys are concatenated. Otherwise, align must have each_seq or each method and works same as EnumerableExtension#alignment_concat.

Returns self.

Note that it is a destructive method.

#each_seq ⇒ Object

Iterates over each sequences. Yields a sequence.

It works the same as Hash#each_value.

end

Returns number of sequences in this alignment.
