Design of the barcoding system. 36 forward and 24 reverse tags were dispensed into nine 96-well plates producing 864 unique combinations of 6-nucleotide sequences named barcodes. 1: reverse tags forming a homopolymer GG with the "key" sequence. 2: reverse tags that could not be recovered because of homopolymer formation (see text for more details).
