Are labs moving quickly to so-called "third-generation" sequencers with accordingly long read lengths? Or is this only used by a handful of people for the time being, for various reasons (too new, too expensive, etc.)? If your lab will soon use this technology, which platform do you intend to use and for what kinds of experiments?
We are using the MinION and are expecting the PromethION in a few months. Since we work on human genetics, the MinION hasn't been of enormous use, yet, because the throughput isn't sufficient for genome sequencing and enrichment for long reads is not really easy. But we're working on that, too.
We are also using MinION essentially for some targeted sequencing of custom long-range librairies or to solve complex badly annotated genomic regions.
Its use is still quite marginal for us but it seems like something really promising.
We will be getting a Promethion soon, but that's not really because we've found Nanopore reads particularly useful so far. They are much harder to deal with than PacBio. I don't think anyone here is really clamoring for it... it's probably more to hedge out bets and stay cutting-edge than anything. That said, the PacBio RSII data has been indispensable in producing high-quality assemblies of repetitive genomes, but we are throughput-limited.
I would rather see a high-quality 2x500bp platform from Illumina, myself, compared to a Promethion.
