 The tool is a simple look up of sequences to find any barcodes that match.

 This is why the same barcodes are found for two different sequences.
+==== A note about old style 10x indexes ====
+// This section is relevant for the single index, four barcodes per sample 10x systems, namely SIGA and SINA. //
+These barcodes, where there are four sequences per sample that are all individual i7 indexes, are searched for any one of the four barcodes: you will be able to find the barcode with any one of the individual sequences used by that barcode. You should not enter four barcodes on a line, as this will locate nothing.
