Bioinformatics Books!

With the start of 2017 Fall semester, the same standard stream of queries on twitter and linkedin comes along - what are some good reference books for bioinformatics Now that is indeed a good question. Bioinformatics itself is something that elicits wows from new acquaintances showing complete ignorance at the term. Moreover folks from all sorts [...]


Bioinformatics tools for VCF files

With the ever growing abundance of Next Generation Sequencing (NGS) data there continues to be a challenge faced by the research community to not only standardize best practices and analysis methods, but to embrace the foray of open-source tools and file formats. Having been engaged since almost the beginning of this NGS data outburst with [...]

The Ebola outbreak of 2014 (Contd.)

Following up on the previous post here are some more detail on the recent Science paper along with a round-up of "what do we know, what have we learned" thus far. The Gire et al paper in Science was huge amount of work and a giant collaborative research effort. Being a computational biology researcher, I [...]

Exomes vs Genomes (re-visited)

The paper by Lupski et al in Genome Medicine provides fuel to the perpetual debate of Whole Exome Sequencing (WES) vs Whole Genome Sequencing (WGS). It takes me down the memory lane to my own presentation "Genomes or Exomes: evaluation of cost, time and coverage" at Beyond the Genome 2011 conference. (If you would like [...]

#ASHG2013 Platform and Poster abstract tag-clouds

With more than 6000 scientists (genetics, bioinformatics, clinicians, statistics, genetic counselor...) and more than 200 companies at Boston for this year's American Society for Human Genetics conference, there is a lot of great science to catch up on. Very quickly, I just pulled out the selected platform talk abstracts, and the poster abstracts (too many [...]

Venn Diagrams Simplified

Not a week goes by without me having to compare multiple lists to evaluate overlap. Re-analyzing any data and comparing that with previously computed data, comparing results from multiple tools or multiple samples. Sometimes the unix commands diff, paste and join come handy, but most times am looking for some additional information. Almost always, am [...]

Journal Club: False-positive signals in exome sequencing

Detecting false-positive signals in exome sequencing Human Mutation I cannot believe that this paper is already a year old. There was a printed copy on my desk, but never got transmitted from the eyes into the brain!! Finally, there was enough time to review the paper and collate all the valuable information to share here. [...]
