As always, very interesting. And above all: Thank you! :-D Can I ask you a few questions? Who are the long read customers and who are the short read customers? Or when do you use what? If long reads are so cheap, why doesn't everyone move to long reads in the future? And you talk about "all these new technologies". What else is worth mentioning? And what about Pacific Biosciences? At the same stage/level as Oxford Nanopore? Perhaps you could touch on some of this in your next videos. Greetings from Germany 🙂

Thanks so much asking and great questions, sorry I didn't cover them in this video! Long reads are used to detect changes in DNA that occur over larger regions or for analysing entirely new DNA sequences (hence we might not have a "reference" to compare it to). Because it covers a larger region, they are more complex to analyse as well, so it's partly a question of knowing what to do with the data plus they require more computational power to analyse. Long reads are "cheaper" in a relatively sense that for Nanopore specifically, it is possible to get started with just the basic kit (called the Minion) without having to purchase a big sequencer to get started, having said that, there is still a bit of work need to "prepare" the DNA sample before feeding it into the the sequencer. The small form factor has meant it's been possible to set up multiple labs in Indonesia during COVID (rather than ship them to a central lab), also they've run Nanopore sequencing in space, and rapidly set up Nanopore to sequence Ebola. I have to confess my knowledge of PacBio is a bit dated and I need to beef up my reading on this. But I am planning to do a comparison between the different long read technologies. It's just that I've had more contact with Nanopore these years, but this is a great prompt for me to look further outside my expertise. Thanks for the great feedback!

@@bad.genome to tag onto BG's response. My background is not necessarily genomics, its techniques or analysis - rather its application, as such my background is haematology. My thought would be not to divide this between who would be LR and SR customers, rather, why would the current body of application jump from SR to LR? Why would I encourage my genomics lab to jump to or have access to this in a practical sense?

Oxford MinION has an application paper in AML targetted sequencing, have also announced PromethiION which technically could run up to 24 sequences simultaneously (If I understood that correctly), and are ambitious to promote their aim to enable 'all context modification sequencing' - the ability to sequence in any context.

Just as a suggestion: when you are putting out some information, you should be careful. Like higher resolution in the case of ONT, that's not true.

Great question! It's how many DNA letters in a row the machine can read at a time. Longer reads are helpful in detecting DNA changes that happen over a large region. They are also great for sequencing DNA that we've never seen before. Having said that, machines that sequence short reads do them at very high resolution (many many short reads) resulting in higher accuracy. So both have their advantages depending on what we're trying to detect. Thanks for asking this.

😂The illumina sales prep told me today that it’s basically just another synthetic long read tech. Useless compared to pacbio and ont.
