From: Levenshtein error-correcting barcodes for multiplexed DNA sequencing
Deficiency of Levenshtein Codes in DNA context. Classical Levenshtein-based codes fail in DNA context as the word boundary is not decodable. Here, the original barcode “CAGG” becomes corrupted through a deletion. The new barcode “CGGC” is now closer to the wrong barcode “CGTC” on the left as opposed to the original barcode “CAGG” on the right.
