  • Computer hardware requirements

    Hello everybody,

    I am new to the next generation sequencing thechnology, and guess that I will be harassing you for a while.
    Let me start off with my first question. As I need to buy a new computer soon, withwhich I'll be performing the analysis of the tremendous sequencing data, I was wondering about the minimal requirements of the computer hardware.
    Hope to read from you soon.
    Greetings,
    Najim

    What organisms are you working on? Small genomes like viruses, modest things like bacteria, or complex genomes like eukaryotes? This has an enormous impact on the amount of data and the amount of memory you'll need.

      I'll be working on the human genome. I want to investigate the possible implementation of NGS for molecular diagnostics of genetic disorders involving large genes and/or multiple genes.

        Najim, I'm doing lots of solexa sequencing of ChIP DNA and only need basic peak finding and bioinformatics so the requirements are modest for me. I built a workstation with a quad-core CPU and 8GB of RAM with velocipartor drives and it screams. For what you are doing I would suspect you will need lots more RAM. I forget where I read it but I think one person doing whole genome sequencing was using an 8-core system with 32GB or RAM. You'll have to have tons of storage space, though. Don't skimp. Get a 16TB RAID array and come up with a good backup/archiving solution for all your data. I quickly filled up a 2TB array, expanded it to 4TB and am working on getting an 8 or 16TB array. This line of experimentation isn't cheap.

          Hi Najim:

          We have been working to develop turn key cluster solutions for different NGS platforms. You may be familiar with our GS FLX Titanium Cluster (www.pssclabs.com/roche) that is available from Roche and works in conjunction with their Titanium sequencer. Based on your sequencing of human genome you may want to consider a cluster based solution. Do you have a time restraint (ie 24 hours) for run time?

            Can you tell us what sequencer instrument are you getting?

              Thanx for the info guys.

              The main purpose of the computer will be mutation detection in specific genomic regions. I didn't realize I'll need that much of RAM memory (32Gb).
              I reckon the sequence data assembly and partial data analysis (base-calling) happens on the workstation, which is coupled to the sequencer.

              We are probably going to get the Illumina sequencer. Firstly, I am planning to perform a pilot sequence run of about 12 multiplexed samples on one lane (about 1 Mb of sequence each). The samples contain several mutation types, such as nucleotide substitions (heterozygous as well as homozygous), micro indels, and large deletions (ranging from one exon to several exons). The run is a success if all mutations feeded to the machine are detected (easily). By the way, I am considering using CLC-bio software. Any suggestions/comments on that matter is greatly appreciated.

              The computer I have in mind has the following specs:
              - memory: 6 Gb RAM
              - Processor: AMD Phenom II X4
              - Hard disk: 1 Tb
              - Videocard: 1 Gb

              What do you guys think?

                Hi Najim,

                Due to the large file sizes there is a lot of IO going on in NGS bioinformatics analysis. For this reason it is a good idea to purchase a machine with fast discs.

                For inspiration, you can have a look at the specs of the machine we have put together:

                      Get your systems administrator to give you some space on one of their racks (another reason to be nice to sys-admins). You should be able to get such a system (depending on how many Us and vendor) for $2,500 - $5,000.

                        Ummm ... where do you get 2 x X5550 and 48 GB RAM for USD 5k? Quotes I've seen were more in the USD 9-9.5k range.

                        B.

                          I wish it was so simple.
                          And yes, that box is not going to be 2k5/5k.. more close to 7k.

                            I'll PM you since I haven't received my commission from that company.

                              Our 2 Xeon quad core, 32GB, 1.5TB Raid5 cost less than 3grand. You have to shop around for the memory and hard drives. And don't forget if you order a tower server the FANs are seriously loud.

                                Exploring the Dynamics of the Tumor Microenvironment
                                by seqadmin




                                The complexity of cancer is clearly demonstrated in the diverse ecosystem of the tumor microenvironment (TME). The TME is made up of numerous cell types and its development begins with the changes that happen during oncogenesis. “Genomic mutations, copy number changes, epigenetic alterations, and alternative gene expression occur to varying degrees within the affected tumor cells,” explained Andrea O’Hara, Ph.D., Strategic Technical Specialist at Azenta. “As...

                                In 2003, researchers from the Human Genome Project (HGP) announced the most comprehensive genome to date1. Although the genome wasn’t fully completed until nearly 20 years later2, numerous large-scale projects, such as the International HapMap Project and 1000 Genomes Project, continued the HGP's work, capturing extensive variation and genomic diversity within humans. Recently, newer initiatives have significantly increased in scale and expanded beyond genomics, offering a more detailed...
