What software exists for sorting multiplexed sequences by their barcode from the same next-generation sequencing run?
(Note: this is talking about DNA barcoding as in distinguishing sequences by an artificial sequence added to an existing sequence, not as in identifying the species of a biological sample based on DNA analysis, the latter described by Wikipedia here)
Try this one https://100bp.wordpress.com/2013/05/08/barcode-splitting-of-ngs-data/. Allows flexible match (several mismatches and redundant DNA characters), two-sided barcoding (to get rid of contamination) and extraction of molecular counter regions (for error correction).
