Accurate sequencing data analysis for under-represented populations: The Pan-African genome

We are excited to announce the release of our GRAF Population Solution, a set of tools, services, and workflows  that enable the construction of genome graph references for targeted populations and/or studies. In this blog post, we discuss some of the advantages of population-specific graphs compared to  methods that rely …

The Annotation Explorer: 1 billion variants, hundreds of annotations, and just a few minutes

With the ongoing proliferation of genome sequencing data, the number of rare variants found is growing rapidly. To detect associations between phenotypes of interest and these rare variants, researchers employ mechanisms to increase statistical power in association testing. Variant annotation information can be used to combine variants into biologically-relevant units …

GATK Best Practice: RNA-seq Variant Calling Workflow on the Seven Bridges Platform

Whether or not variant calling should be performed on RNA-seq data and its possible benefits is a debatable topic. One thing is for certain, if you have already sequenced the transcriptome with the intent to analyze gene expression, but you are also interested in exploring variants existing in the same …

Assessing State of the Art Bioinformatics

The Oxford English Dictionary defines bioinformatics as “the science of information and information flow in biological systems, especially of the use of computational methods in genetics and genomics.” In common vernacular, it is often defined as the use of statistical and computing methods to solve or better understand complex biological …

Enabling Workflow Reproducibility in the Cloud with New Pipelines from the Genomic Data Commons

When analyzing genomic data, there is a vast range of bioinformatics tools and workflows to choose from. However, making an informed selection from so many options can be overwhelming, even within a relatively narrow topic, such as harmonization to a reference genome. One approach to selecting the right tool for …

Bioinformatics Workflow Portability is Critical to Achieving Reproducibility

With the explosion of genomic data in recent years, the number of bioinformatics workflows has seen a corresponding proliferation. Researchers and developers now have a wealth of analysis options, from building their own tools to taking advantage of those developed by others. However, a workflow developed in one environment may …
