Hi, the new versions of MinKNOW allows to demultiplex with the option “requiring barcodes at both ends”, which is what we need for the artic pipeline. However, recently not just the fastq files but also the fast5 files…

</div>

If we run rampart, can we “skip ahead” in the informatics? Or should we re-base call the Fast5 and re-demux, per the bioinformatics SOP. It seems redundant, but it also seems like it what people are doing?

We have historically used fast basecalling on laptops for small scale ONT work, but ultimately would like to use high accuracy basecalling (HAC) going forward. We have therefore moved to HAC (gridion) for our production …

ARTIC tools use porechop to re-demultiplexing the samples obligatorily. However it take too much time in my SERVER like 8G fastq per day. Anyway to accelerate the process?
