In an experimental design, we know which locus-specific barcodes go with which regional barcodes, so to avoid using the same locus-specific spot multiple times when 2 regional barcodes' spots happen to be close and both overlap it, and to avoid exacerbating the potential problem of sample autofluorescence causing false locus-specific spots, we should use that a priori knowledge to ignore locus-specific spots for which (expected_ref_frame(frame) =!= ref_frame).
