    Yikes! You probably know your sales person well by now. It is possible that (s)he may not have been aware of the new sequencer until this week. At least that was my impression from some past conversations.

    With AGBT so close, it remains to be seen if we will see another major announcement there.

    And while sequence is sequence regardless of instrument, $/Gbp do matter to researchers. We were loosing business because we had a 2500 as our top instrument and researchers were going elsewhere to get cheaper sequencing done on a 4000. I fear the in a year's time, when enough NovaSeq's are in the field we will be right back in the same boat.
    That is a true concern. Some institutions subsidize their cores in creative ways and competing fairly (on price) with such cores becomes very hard. Unfortunately these are things that you can't control.

    All that said, after digging into the specs (as sparse as they are) it looks to me as though the NovaSeq flow cells are single sample, like the NextSeq. Not a single bit of the literature uses the word "lane". If that is the case then its target market isn't a core like ours. If indeed each flow cell is loaded with a single sample then it would not be a nightmare for a core like ours to coordinate multiple projects to fill up one massive sample load.
    Specs talk about 132 exomes/transcriptomes per run so perhaps the idea is to load one single pool (of many) on every run, if there are no independent "lanes" See next post.

    Creating a big pool with compatible samples would be a headache for a core as some customers like to make their own libraries to save costs.

    Having seen a string of new sequencers over the years I feel that I would rather have someone else do the bug hunting/fixing in the first year with a new instrument. It may be better to buy the sequencer in the second year, when you are much less likely to face these "growing pains".

    If one is going for the "bragging rights" then there is no space for above logic.

    Our core just bought a new 4000, and by just, I mean installed last week. Explains why Illumina was pushing us all throughout December to get the PO submitted.

    Small cores like ours appreciate the flexibility of the 2500, which can accommodate 16 samples per run (minimizing staff time) or two (good for uncommon sequencing requests). It's essentially a 4000 plus NextSeq in one instrument (without the limitations of two-color chemistry associated with the latter), albeit with less data output. Since many of our users already obtain more data per lane than needed (think RNA-Seq/ChIP-Seq with limited number of samples), it's an acceptable tradeoff.

    Illumina will of course say it is impossible to do the same with the current sequencers (reduce distances between nanowells).

    Similar there seem to be no single end flow cells and only PE150 read kits for two the highest read number flowcells.

    Summary of NovaSeq Specs

    Biggest change is NovaSeq's reduction in space between nanowells, designed to increase cluster density and data output (up to 2-3x more per flow cell than HiSeq X). Notable is the omission of Nextera based exome and Nextera DNA library prep in the initial compatibility line up.

    Summarized specs here: https://blog.genohub.com/2017/01/10/...5000-and-6000/

    Novoseq-a terminator for ALL HiSeq platforms???

    started a topic NovaSeq from Illumina

    NovaSeq from Illumina

    Illumina just announced a new type of sequencer: NovaSeq

    Specifications are here.

    NovaSeq 6000 - 6 Tb data/20 billion reads in 2 days
    NovaSeq 5000 - 2 Tb data/1.6 billion reads in 2.5 days

    Flowcells

    S1,S2 - Flowcells for counting applications

    For S2 - PF 1775-2070 cluster/mm^2

    S3,S4 - High coverage applications

    Same cartridges on both sides (three total).

    Reagent Cartridge - Will take one library tube (200-300 pM) per FC
    SBS Reagents - Frozen
    SBS Buffers - Room temperature ship/store. Ready to use.

    - FC looks huge, like NextSeq. Easy to place. No futzing needed.

    - Run setup identical to current HiSeq sequencers.

    - Mix/match flowcells.

    - Two sides of the instrument can work independently (stream data to BaseSpace on on side, store locally on other side).

    - Automatic post-run wash once sequencing is complete

    - Run times includes cluster generation.

    - Network speed (200 mbps)

    - ONE library pool per flowcell. Lanes visually distinct but fluidically identical

    - Both 5000/6000 are dual FC systems. For 5000 systems run times slightly longer

    - Custom primers possible

    - Asymmetric runs possible (e.g. 100 x 75)

    - No "Rapid" run capability needed (Illumina's take)

    - FC's can be used for single and paired-end recipes

    - ExAMP, all self contained in the sequencer

    - 200/240V, adequate HVAC

    Test NovaSeq data is available on BaseSpace.
