I've theoretically had access to the data since Saturday, but a series of events (computer-free weekend, a crashed home computer, a personal day & a good but unbloggable conference) have meant that ambitious plans to analyze it are still in progress. So, what I discuss below is either from Ion's provided information or other sources, so take it with appropriate caution. The first statistic of note is that their dataset has 1.69M reads, with 1.53M of those >=50 bp long and 1.07M 100bp or longer. No enormous gains in read length in this dataset, though the curve might be shifted towards longer (one of the many analyses still being done). Now, the question immediately arises as to how typical this run is; their public dataset from the prior 314 chip with >400K reads is clearly an outlier.

This approach marries simple chemistry to proprietary semiconductor technology—it's Watson meets Moore. The result is a sequencing technology that is simpler, faster, and more cost effective and scalable than any other next-generation sequencing technology available.

An integrated semiconductor device enabling non-optical genome sequencing : Nature. IonTorrent: Benchtop Sequencing, Streamlined. New, smaller sequencing instruments are finding niches everywhere.
Earlier this year in Less Is More: Sequencing on the Benchtop, I profiled three pint-sized sequencing instruments designed for next-gen sequencing on the benchtop: IonTorrent’s PGM, the Illumina MiSeq, and 454′s GS Junior. I must admit that I’m most intrigued by the PGM, probably because the idea of semiconductor sequencing is just so fascinating. One concern that I’ve heard about the PGM, however, was sample preparation. The time requirement and difficulty of sample prep was an immediate question at AGBT when Jonathan Rothberg first presented the instrument.
He dodged the question, and I don’t think there’s been a satisfactory answer since. Priced at under $5,000, and measuring 1′ x 1′ square, the OneTouch requires “five minutes of hands-on time” and takes a few hours to run. PGM Applications. First Look: Data from IonTorrent’s 316 Chip. I got an early look at data from IonTorrent’s forthcoming semiconductor sequencing chip, called the 316.
The data comes from a single sequencing run of E. coli, specifically the laboratory reference strain DH10B, not to be confused with the hybrid E. coli strain in the European outbreak that IonTorrent sequenced earlier this year. According to the run report, some 1.69 million reads were generated, of which 1.35 million were 100 base pairs or longer. It’s a nice, shiny report with color images, and of course I summarily ignored it in favor of looking at the data myself. The data package included an SFF file, a data format often used for Roche/454 data that contains read sequences and base qualities.
There was also a BAM file, which included the read sequences aligned to the E. coli reference, indexed for random access. Distribution of Read Lengths. Life Technologies. Job als Account Manager / Sales Rep Ion Torrent Germany » Experteer. Diese Stelle ist nicht mehr verfügbar!
Serotype O104:H4, which has not been detected in animals, has rarely been associated with HUS in the past. To prospectively elucidate the unique characteristics of this strain in the early stages of this outbreak, we applied whole genome sequencing on the Life Technologies Ion Torrent PGM™ sequencer and Optical Mapping to characterize one outbreak isolate (LB226692) and a historic O104:H4 HUS isolate from 2001 (01-09591).
Reference guided draft assemblies of both strains were completed with the newly introduced PGM™ within 62 hours. Open-Source Genomic Analysis of Shiga-Toxin–Producing E. coli O104:H4. Nutzerprofil: Keith Robison. Education Home. Nature.
