Detailed Description

template<typename end_gaps_t>
struct seqan3::align_cfg::aligned_ends< end_gaps_t >

The configuration for aligned sequence ends.

Template Parameters

end_gaps_t

The type of the end-gaps. Must be a specialisation of seqan3::end_gaps.

This configuration element configures the aligned ends to further refine the global alignment algorithm. Particularly, the ends of the alignment can be penalised with gap costs or not. For example, the semi-global alignment does not penalise the leading and trailing gaps of one sequence while it does for the other sequence.

The class is instantiated with an object of seqan3::end_gaps. The user can configure each of the gap specifier separately allowing for maximal flexibility when configuring the alignment algorithm. However, there are also predefined configurations which should be preferred whenever possible.

If this configuration element is not specified for the alignment algorithm, it will automatically default to free_ends_none which computes a global alignment.

Example

#include <seqan3/alignment/configuration/align_config_aligned_ends.hpp>
#include <seqan3/core/debug_stream.hpp>
 
int main()
{
    // Setup for overlap alignment.
    seqan3::align_cfg::aligned_ends overlap{seqan3::free_ends_all};
 
    // Setup for global alignment.
    seqan3::align_cfg::aligned_ends global{seqan3::free_ends_none};
 
    // Setup for semi-global alignment with free-end gaps in the first sequence.
    seqan3::align_cfg::aligned_ends semi_seq1{seqan3::free_ends_first};
 
    // Setup for semi-global alignment with free-end gaps in the second sequence.
    seqan3::align_cfg::aligned_ends semi_seq2{seqan3::free_ends_second};
 
    // Custom settings.
    seqan3::align_cfg::aligned_ends custom{seqan3::end_gaps{seqan3::front_end_first{std::true_type{}}, seqan3::front_end_second{std::true_type{}}}};
}
