I'm a happy user of the DNABarcodes package by Tilo Buschmann. I came across the paper by Hawkins, John A., Stephen K. Jones, Ilya J. Finkelstein, and William H. Press. 2018. “Indel-Correcting DNA Barcodes for High-Throughput Sequencing.” Proceedings of the National Academy of Sciences 115 (27): E6217–26. https://doi.org/10.1073/pnas.1802640115 where they state that
... but an error in the derivation of these codes [Buschmann & Bystrykh 2013] often causes the decode spheres to overlap, resulting in wrong barcode decodings (SI Appendix) ...
Buschmann & Bystrykh 2013 is the paper on which the DNABarcode package is based. I coudn't quite follow the argument but does anyone know if this (still) the case? And if so, under which circumstances?
