SVS, Population Genetics, and 1000 Genomes Phase 3

One frequent question I hear from SVS customers is whether whole exome sequence data can be used for principal components analysis (PCA) and other applications in population genetics. The answer is, “yes, but you need to be cautious.” What does cautious mean? Let’s take a look at the 1000 Genomes project for some examples.

VarSeq: A bioinformatics Swiss Army knife

If you’ve seen the recent webinars given by Gabe Rudy and Bryce Christensen, you’ve no doubt been impressed by the capabilities of VarSeq when it comes to annotation and filtering. However, we sometimes forget that the power that enables all this complex analysis can also be used in more mundane tasks like VCF subsetting. And although these day-to-day tasks don’t… Read more »

A little known fact about Box Plots

A helpful tool that is included in SVS, but many of our customers may not know about, is the ability to create Box Plots or box-and-whisker plots. These are effective visualizations for comparing groups of numerical data through the data quartiles. I’ll take you through a couple different cases with examples.

Turning SRA Files Into Usable BAMs and VCFs

In our recent webcast, Advancing Agrigenomic Discoveries with Sequencing and GWAS Research, Greta Linse Peterson featured bovine data which she download from the NCBI website. The data was downloaded in SRA format and in order to analyze the data in SVS, the files had to be converted to BAMs and then merged into a single VCF file. Since many of… Read more »
