Instance Method Details

#check_for_barcodes_unique ⇒ Object

For plate manifests the barcodes (sanger plate id column) should be the same for each well from the same plate, and different for each plate. Uniqueness of foreign barcodes in the database is checked in the specialised field sanger_plate_id.
