Wondering what SVS can do for a PhD student? Just ask Sander.

         September 14, 2011

Sander van der Laan is like many Ph.D. students in the genomic analysis space. He has a lot of data and a lot of ideas about how to analyze it. His professor wants results. He’s the only one doing genetics (everyone else in his department is doing proteomics), so there’s always too much to do. And he finds command-line tools… Read more »

Ever since the release of SNP & Variation Suite (SVS) 7.4 back in January, our software engineers have been hard at work developing new functionality for the next version, to enable researchers to have even more control over their data. (Okay, well really, they started working on it before 7.4 even came out.) While the full details of 7.5 are… Read more »

Summary and Q&A: “A Genome-wide Comparison of the Functional Properties of Rare and Common Genetic Variants in Humans”

         May 24, 2011

The common disease-common variant hypothesis has established the foundation of SNP-basis genome-wide association studies for the last several years. However, with few strong associations found, researchers are beginning to consider the effects of rare variants through the burgeoning availability of DNA sequencing. Qianqian Zhu and Dongliang Ge, of the Center for Human Genome Variation at Duke University, and others recently… Read more »

“Dammit Jim, I’m a doctor, not a bioinformatician!”

Academic Software, Productivity, and Reproducible Research httpv://www.youtube.com/watch?v=pGMLCxKPMSE&NR=1 Do you ever feel like Dr. McCoy on Star Trek, where your job and expertise is to do x, but to achieve your goals you also have to do y and z, which you either don’t want to do or don’t have the skills to do? Genetic researchers are faced with this every… Read more »

NGS Tools and Formats for Secondary Analysis: A Primer

         April 20, 2011

In a series of previous blog posts, I gave an overview of Next Generation Sequencing trends and technologies. In Part Two of the three part series, the range of steps and programs used in the bioinfomatics of NGS data was defined as primary, secondary and tertiary analysis. In Part Three I went into more details on the needs and workflows… Read more »

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 »
