  • Won’t bore you with the entire history of Edge Bio. Its been around 20 …I am sure there are several of you in this room that found yourself doing something you didn’t expect because NGS has provided new challenges to typical thinking and infrastructure.
  • I am sure you all have seen some sort of variation of this. You, like us, see the value in exploring the next gen landscape, but with such an infection – something has to give.Figure 1 The number of publications with keywords for nucleic acid detection and sequencing technologies. PubMed (http://www. ncbi.nlm.nih.gov/sites/entrez) was searched in two-year increments for key words and the number of hits plotted over time. For 2007–2008, results from January 1–March 31, 2008 were multiplied by four and added to those for 2007. Key words used were those listed in the legend except for new sequencing technologies (‘next-generation sequencing’ or ‘high-throughput sequencing’), ChIP (‘chromatin immunoprecipitation’ or ‘ChIP-Chip’ or ‘ChIPPCR’ or ‘ChIP-Seq’), qPCR (TaqMan or qPCR or ‘real-time PCR’) and SNP analysis (SNPs or ‘single-nucleotide polymorphisms’ and not nitroprusside (nitroprusside is excluded because sodium nitroprusside is sometimes abbreviated as ‘SNP’ but is generally unrelated to genetics)).
  • From the base of the inflection (or tipping point) in 06 - innovation and technology have been in a constant state of flux. Costs per base have plummeted.Still remains as significant capital expenditure in many areas
  • Lets hone in on a couple of those areas.- These are the players in the sequencing field as it is, and as it is emerging. - Where do you start – each are provide data at lower costs,- Each have their strengths and weaknesses, - How do you make sure you choose the right platform for your application.
  • Now, you have a platform – with the high throughout comes an immense range of applications – how do you become proficient?
  • Now you have an application, how do you design your project? And what many here are talking about today – how do you effectively analyze the data?To illustrate the complexity – this is a partial list of read mapping software from SeqAnswersSo testing, comparing, and honing in on an app is important. Then each one can be run in a multitude of ways. How many errors, colorspace, base, space, etc, Daunting,
  • Then there is the execution and operations of the projects, - We all wish we had a bag of money to do the science “in the right way”compromises are made to suit funders, timelines, quality standards, etc.How do we balance those limited resources – lets touch on that later.
  • I tend to start with the inherent challenges of the next gen landscape to lay the ground work for possible solutions.
  • I was lucky to grow up in genomics. 16 was high throughput. Infrastructureas we know it was rendered obsoletesheer scalechemistries (flows and colorspace data) error models.– significant issue lie ahead for next next gen in these areas.
  • Distributing the Problem- lower barrier to entry than before- it has somewhat democratized sequencing,
  • - Service based models becoming common in IT- They allow abstractions, so you don’t have to care about the hardware, or the software, or the platform that is built to accomplish the goals of the research organization or company.
  • Edge abstracts it to the most basic of levels. Our aim is to help researchers with all these considerations, to come out with optimal results. DNA/RNA in  answers out.
  • Though leaders in fields of genomics and bioinformatics.
  • Lets focus a bit more. Bioinformatics is a piece of the puzzle.
  • More recently, it just so happens to be a larger piece.
  • With limited time and so many cool things to talk about – I am going to touch on several. I would love to continue any one of these in a hallway or over coffee. My group’s goal is to leverage many technologies – commercial, academic, and internal to help our clients. Some of the areas we are focusing on are on this slide.
  • SO the first, and probability hottest topic out there is cloud.
  • ScalablePay as you GoRedundant data storageUbiquitous accessLower upfront and capital costs
  • Access resources in non-traditional ways.Paradigm shift needs to happen with funding agencies,think in traditional ways of funding capital infrastructure. We need to continue to educate.
  • - Oneneeds to be nimble in their ability to leverage computes from many pools. - With the ESG, we have built a flexible and scalable infrastructure
  • ESG is built around This plug and play architecture- continue to explore tools - Chef and other virtualization mechanism that ease the burden of infrastructure maintenance.
  • Note how each is a node which we can hotswap tools as needed.
  • This isn’t Panaceathough. There are are costs, whether front or back loaded. SO how do we minimize them? Spend time making things better, not just building pipelinesI’ll touch a bit more on each of these in the upcoming slides.
  • - Best of Breed. - Changing so rapidly. SOwhether we, or someone else figures out a way to do something better we can take advantage.- With software, make it better or run it less
  • How many times have you tried to install software that was sent to you or you downloaded from SourceForge that wouldn’t build or run as planned?We quickly learned with a community based AMI is very serial in its adoption and addition. Chef allows for developers to construct infrastructure much like SW
  • So, lets wind this down by looking at some examples. I guess if you take one term away – I would like it to be Science as a Service. This is a concept, an abstraction for a method of building infrastructure and transparency. So – does it work?
  • Note how each is a node which we can plug in tools as needed.
  • Balance between cost and coverage – this provides a talking point for a slide coming up in a few.
  • What is the best way to do this with what you have?If money not an object, get high coverage and 100% accuracyIn reality, What is the best way to do it with what you have?PlaftormBfx
  • What is the best way to do this with what you have?If money not an object, get high coverage and 100% accuracyIn reality, What is the best way to do it with what you have?PlaftormBfx
