Hi Community,

I have run Guppy on naopore reads for the basecalling and generated a final merged fastq file. Next, for demultiplexing I have seen a couple of option available, such as Porechop, Last and qcat. Can anyone suggest me from their earlier experience which tool I should use for demultiplexing of the basecalled fastq reads? As an input data i have the a .fastq file and one fasta file with all the barcode.

Could you please let me know the running command. I checked the manual it looks like : porechop -i input_reads.fastq.gz -b output_dir here, how i should provide my input barcode fasta file?

Scroll down at the link above. Looks like you need to edit adapters.py script and add them if you use custom barcodes.

Do you use Guppy for basecalling or any other tool?

Sorry, I didn't notice your first comment. You should manually edit the adapters.py file to add barcodes. I use guppy for basecalling and then porechop for demultiplexing or trimming when non-standard adapters are used.
