Member seqan3::sam_record< field_types, field_ids >::alignment () &&: Please access cigar() and then use seqan3::alignment_from_cigar to retrieve the alignment.
Member seqan3::sam_record< field_types, field_ids >::sequence_position () &&: This member is deprecated please access the seqan3::sam_record::cigar() information directly and check the value for soft clipping (S) at the front of the CIGAR string. It is synonym to the offset. If not soft clipping is present at the front, the offset is zero.
