Public Instance methods

alignment(method = nil)

Gets an multiple alignment. Returns a Bio::Alignment object. method should be one of :naseq, :aaseq, :seq, or nil (default). nil means to automatically determine nucleotide or amino acid.

This method returns previously parsed object if the same method is given (or guessed method is the same).
