From: BARCOSEL: a tool for selecting an optimal barcode set for high-throughput sequencing
Nucleotide balances of optimal sets with varying number of barcodes. Horizontal axis is the barcode position, total indicates the nucleotide balance over the entire barcode length. In Illumina sequencing, nucleotide groups A/C and G/T should be in balance for optimal detection in each position. Total balance is important for equal consumption of nucleotides during sequencing. a 10 barcodes. b 11 barcodes. c 12 barcodes. d 75 barcodes
