Configuring SNP detection pipelines for accurate analysis of clinical samples

Webinar of the Month Series: Configuring SNP detection pipelines in Avadis NGS for accurate analysis of clinical samples Presenter:  Dr Vamsi Veeramachaneni, Vice President, Strand Life Sciences Abstract: Running a SNP detection pipeline and identifying high quality variant calls quickly is challenging. This is especially true in the case of clinical labs where multiple panels … Continue reading “Configuring SNP detection pipelines for accurate analysis of clinical samples”

Mapping RefSeq transcripts to the genome using UCSC

Transcript annotations are extensively used in NGS data analysis. In RNA-Seq, they are used at every step of the pipeline – to map spliced reads against the genome, perform quantification, detect novel exons etc. In DNA-Seq, they are used to predict the effect of variants detected in the sample. Clearly accurate transcript annotations are vital … Continue reading “Mapping RefSeq transcripts to the genome using UCSC”

From yeast to mice to chicks to stem cells – 4 ways RNA-Seq analysis sheds light on the world around us (a four part series)- Part II

In my previous blog post, I had walked you through a yeast paper where the authors had mapped its mitochondrial trancriptome. They had used the RNA-Seq analysis tool from Avadis NGS in clever ways to figure out details about the transcriptome that played a key role in piecing together the final map. In this week’s … Continue reading “From yeast to mice to chicks to stem cells – 4 ways RNA-Seq analysis sheds light on the world around us (a four part series)- Part II”

From yeast to mice to chicks to stem cells – 4 ways RNA-Seq analysis sheds light on the world around us (a four part series) – Part I

Last month, as in my wont, I was taking a look at publications that had very recently used our software for analysis of NGS data. Of these, four were by groups who had used the RNA-Seq workflow from the Avadis NGS suite to run the analysis of their data. Intrigued by the fact that this … Continue reading “From yeast to mice to chicks to stem cells – 4 ways RNA-Seq analysis sheds light on the world around us (a four part series) – Part I”

A Sneak Peak at Avadis NGS Version 1.5’s New Features!

The release date for the next version of Avadis NGS is just around the corner. Not only does the software include a lot of refinements in some of the older features, but it also boasts of a number of cool new ones! So here is a sneak peak at some of these features in version … Continue reading “A Sneak Peak at Avadis NGS Version 1.5’s New Features!”

The Need for Realignment to dbSNP

We’ve been using Avadis NGS to analyze a number of clinical samples and ran into an interesting case for InDel detection that could lead to false interpretation unless handled properly. The case at hand involves a child who suffered from Pulmonary Hypertension, Pulmonary Infections, and a few other abnormalities, all at birth or in the … Continue reading “The Need for Realignment to dbSNP”

How Identical are Identical Twins?

We’re looking at exome sequencing data on whole peripheral blood DNA of monozygotic twins (this data was generated by our collaborators, Jan Dumanskiand his group at Uppsala University in Sweden). Monozygotic twins were earlier thought to be genetically identical; now we know that isn’t completely true. How does one identify small mutations (SNPs and small … Continue reading “How Identical are Identical Twins?”

Welcome to our blog

Our goal for this blog is to be a distraction that is useful for you as well as for us. We will use this venue to express our bewilderment and discoveries as we traverse the genome. Mostly, we’ll geek out over puzzling challenges in bioinformatics, but we may also delve into other relevant topics – … Continue reading “Welcome to our blog”
