None barcode

[BOM86]

Dear rrwick,

I have been using Porechop for some time now and it works very well! However, now I tried to demultiplex a sample which contains only one barcode and all my reads end up in the None.fastq file. I have checked the sequences and it is not a problem that the barcode could not be found, they can be identified but for some reason they are not binned...

I have attached a part the output (verbosity 3):

Do you know how to solve this problem?
