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'.

#include <seqan3/alphabet/nucleotide/sam_dna16.hpp>
#include <seqan3/core/debug_stream.hpp>
 
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 << '\n'; // "N";
}
