Detailed Description

Quality type for PacBio Phred scores of HiFi reads.

The phred94 quality alphabet represents the zero-based Phred score range [0..93] mapped to the ASCII range '!' .. '~'. It is typically used for HiFi reads produced by PacBio. For Sanger and Illumina Phred scores of raw reads the range is typically (0 to 41), represented as seqan3::phred42. If you expect only slightly larger score types you can use seqan3::phred63 (0 to 62) which still has memory advantages when used with seqan3::qualified.

#include <seqan3/alphabet/quality/phred94.hpp>
#include <seqan3/core/debug_stream.hpp>
 
int main()
{
    seqan3::phred94 phred;
    phred.assign_phred(2);
    seqan3::debug_stream << phred.to_phred() << "\n"; // 2
    seqan3::debug_stream << phred.to_char() << "\n";  // '#'
    seqan3::debug_stream << phred.to_rank() << "\n";  // 2
 
    seqan3::phred94 another_phred{75};
    seqan3::debug_stream << another_phred.to_phred() << "\n"; // 75
 
    seqan3::phred94 a_third_phred;
    another_phred.assign_phred(105); // converted down to 93
    seqan3::debug_stream << another_phred.to_phred() << "\n"; // 93
}

This entity is stable. Since version 3.1.

Parameters

[in]	s	A pointer to the character sequence to assign from.
[in]	n	The length of the character sequence to assign from.

Returns: seqan3::std::vector<seqan3::phred94>

You can use this string literal to easily assign to std::vector<seqan3::phred94>:

#include <seqan3/std/algorithm>
 
#include <seqan3/alphabet/quality/phred94.hpp>
#include <seqan3/core/debug_stream.hpp>
 
int main()
{
    using seqan3::operator""_phred94;
 
    // directly assign to a std::vector<phred94> using a string literal
    std::vector<seqan3::phred94> qual_vec = "###!"_phred94;
 
    // This is the same as a sequence of char literals:
    std::vector<seqan3::phred94> qual_vec2 = {'#'_phred94, '#'_phred94, '#'_phred94, '!'_phred94};
 
    seqan3::debug_stream << std::ranges::equal(qual_vec, qual_vec2) << '\n'; // prints 1 (true)
}
