CAOS-R : character-based barcoding

CAOS-Barcoding is a culmination of traditional taxonomy and modern DNA barcoding. CAOS identifies taxa by diagnostic characters as is done in traditional taxonomy and produces an identification matrix for taxon discrimination similar to DNA barcoding distance matrices. Here, I describe how to set up the CAOS-Barcoder and CAOS-Classifier software, which input data is needed, and how to interpret the output data. With the CAOS-Barcoder, single marker or concatenated data can be processed into diagnostic barcodes for taxon discrimination. The CAOS-Classifier can use the diagnostic barcodes for specimen identification.
