Demultiplexing refers to the step in processing where youd use the barcode information in order to know which sequences came from which samples after they had all be sequenced together. Barcodes refer to the unique sequences that were ligated to your each of your invidivual samples genetic material before the samples got all mixed together. The DADA2 and u-/v-search tutorials on this stie both take off assuming your samples have already been demultiplexed. Demultiplexing refers to the step in processing where youd use the barcode information in order to know which sequences came from which samples after they had all be sequenced together. Web-based database system for flow cell management (incl. Accurate Demultiplexing Unique dual indexes reduce per-sample cost and sequence libraries with the highest accuracy compared to other indexing strategies. The nanopore sequencing analysis workflow is simple and easy to follow: with five steps from raw data acquisition to analysis completion and experimental interpretation.
