Detailed Description

A 16 letter DNA alphabet, containing all IUPAC symbols minus the gap and plus an equality sign ('=').

The seqan3::sam_dna16 alphabet is the nucleotide alphabet used inside the SAM, BAM and CRAM formats. It has all the letters of the seqan3::dna15 alphabet and the extra alphabet character '=' which denotes a nucleotide character identical to the reference. Without the context of this reference sequence, no assumptions can be made about the actual value of '=' letter.

Note that you can assign 'U' as a character to sam_dna16 and it will silently be converted to 'T'. Lower case letters are accepted when assigning from char (just like seqan3::dna15) and unknown characters are silently converted to 'N'.

The complement is the same as for seqan3::dna15, with the addition that the complement of '=' is unknown and therefore set to 'N'.

int main()
{
using seqan3::operator""_sam_dna16;
seqan3::sam_dna16 my_letter{'A'_sam_dna16};
my_letter.assign_char('=');
my_letter.assign_char('F'); // unknown characters are implicitly converted to N.
seqan3::debug_stream << my_letter << std::endl; // "N";
}

Member Function Documentation

◆ assign_char()

constexpr sam_dna16 & seqan3::alphabet_base< sam_dna16 , size, char >::assign_char ( char_type const  c)
inlineconstexprnoexceptinherited

Assign from a character, implicitly converts invalid characters.

Parameters
cThe character to be assigned.

Provides an implementation for seqan3::assign_char_to, required to model seqan3::alphabet.

Complexity

Constant.

Exceptions

Guaranteed not to throw.

◆ assign_rank()

constexpr sam_dna16 & seqan3::alphabet_base< sam_dna16 , size, char >::assign_rank ( rank_type const  c)
inlineconstexprnoexceptinherited

Assign from a numeric value.

Parameters
cThe rank to be assigned.

Provides an implementation for seqan3::assign_rank_to, required to model seqan3::semialphabet.

Complexity

Constant.

Exceptions

Guaranteed not to throw.

◆ char_is_valid()

static constexpr bool seqan3::nucleotide_base< sam_dna16 , size >::char_is_valid ( char_type const  c)
inlinestaticconstexprnoexceptinherited

Validate whether a character value has a one-to-one mapping to an alphabet value.

Satisfies the seqan3::semialphabet::char_is_valid_for() requirement via the seqan3::char_is_valid_for() wrapper.

Behaviour specific to nucleotides: True also for lower case letters that silently convert to their upper case and true also for U/T respectively, e.g. 'U' is a valid character for seqan3::dna4, because its informational content is identical to 'T'.

Complexity

Constant.

Exceptions

Guaranteed not to throw.

◆ complement()

constexpr sam_dna16 seqan3::nucleotide_base< sam_dna16 , size >::complement ( ) const
inlineconstexprnoexceptinherited

Return the complement of the letter.

See Nucleotide for the actual values.

Complexity

Constant.

Exceptions

Guaranteed not to throw.

constexpr char_type seqan3::alphabet_base< sam_dna16 , size, char >::to_char ( ) const
inlineconstexprnoexceptinherited
