Blankenberg et. al. section 2.4.2: "This requires the genomic positions of each species in the blocks-to-be-joined to have genomic positions that start and end directly adjacent to each other. When joining, the strand of each sequence is important, as positions listed in opposing orientations are considered different even if they are equivalent locations."
