I Want a GPU for Computational Analysis! Which One Should I Get?

         April 14, 2011

A GPU can produce an enormous boost in performance for many scientific computing applications. Since we announced the availability of SNP & Variation Suite’s incorporation of GPUs to dramatically speed up copy number segmentation, we’ve received numerous inquiries on recommendations for what GPU to purchase. Unfortunately the technical terminology and choices can be a bit confusing. In this article I… Read more »

Checking Relatedness and/or Inbreeding in Samples as a Quality Assurance Measure

         February 10, 2011
James' whiteboard with IBD calculations

Almost every statistic that is used for significance testing in scientific research comes with a set of assumptions. If the test is applied to data that does not meet those assumptions, then the results of the test may not be valid. The statistics commonly used in genome-wide association studies (GWAS), such as the Fisher’s Exact Test or the Chi-Square Test,… Read more »

A Hitchhiker’s Guide to Next Generation Sequencing – Part 3

         January 19, 2011

The advances in DNA sequencing are another magnificent technological revolution that we’re all excited to be a part of. Similar to how the technology of microprocessors enabled the personalization of computers, or how the new paradigms of web 2.0 redefined how we use the internet, high-throughput sequencing machines are defining and driving a new era of biology. Biologists, geneticists, clinicians,… Read more »

A Hitchhiker’s Guide to Next Generation Sequencing – Part 2

         December 9, 2010

When you think about the cost of doing genetic research, it’s no secret that the complexity of bioinformatics has been making data analysis a larger and larger portion of the total cost of a given project or study. With next-gen sequencing data, this reality is rapidly setting in. In fact, if it hasn’t already, it’s been commonly suggested that the… Read more »
