Mission Bio Launches Tapestri Single Cell Platform

written 1 day ago by Omics! Omics! by Keith Robinson

The fact that tumors and their immediate environment is genetically heterogeneous has long been known, but tools for high-throughput assessment of this heterogeneity have only recently become available. The whole field of single cell RNA-Seq has seen spectacular growth, as new methods enable greater and greater numbers of cells to be profiled from a sample. Profiling the DNA content on an individual cell basis has not been quite as much in the spotlight, but now a start-up called Mission Bio is launching a microfluidic library prep workflow, Tapestri, to enable amplicon panels to be run in single cell mode.Read more »

Preview and where to find me at ASHG 2017

written 2 days ago by MassGenomics by Dan Koboldt

This week I’ll be at the American Society of Human Genetics annual meeting in Orlando, Florida. This meeting is the largest gathering of human genetics professionals (over 7,000 attendees) and offers, in my opinion, one of the best educational opportunities for our field. One reason it’s so valuable is simply the diversity of scientific content […]

iGenomX Riptide Kits Promise a Sea of Data

written 5 days ago by Omics! Omics! by Keith Robinson

A theme for me in my six years on Starbase has been addressing the challenge of cost-effectively sequencing many small genomes. While sequence generation bulk prices have plummeted, all-in library construction cost has tended to stubbornly resist dramatic change. Large genome projects don't face quite such a pinch, but if you want to sequence thousands of bacteria, viruses or molecular biology constructs, paying many-fold more for getting a sequence into the box than you're paying to move it through the box ends up being a roadblock. Illumina's Nextera approach dropped prices a bit, but not really a sea change. Various published protocols drop costs further via reagent dilution, but these can suffer from variable library yield and an increased dependence on precise input DNA quantitation and balancing. Even then, the supplied barcoding reagents for Nextera handle at most 384 samples, and that is only a relatively recent expansion from 96. I previously profiled seqWell's plexWell kits, which like Nextera use a transposase scheme but with modifications to enhance tolerance to input sample concentration variation. plexWell also enables very high numbers of libraries, which better mates projects with large numbers of small genomes to sequencers with enormous data generation capabilities. Now comes another entrant in the mass Illumina library generation space: iGenomX, which has reformatted their chemistry from a microdroplet mode intended for linked read generation to a 96-well plate format requiring no unusual hardware.Read more »

XML parsing made easy: is that podcast getting longer?

written 6 days ago by What You're Doing Is Rather Desperate by Neil Saunders

Sometime in 2009, I began listening to a science podcast titled This Week in Virology, or TWiV for short. I thought it was pretty good and listened regularly up until sometime in 2016, when it seemed that most episodes were approaching two hours in duration. I listen to several podcasts when commuting to/from work, which … Continue reading XML parsing made easy: is that podcast getting longer?

A reminder that when idle queries pop into your head, the answer can often be found using R + online data. And a brief excursion into accessing the Weather Underground. One interesting aspect of Australian life, even in coastal urban areas like Sydney, is that sometimes it just stops raining.

PacBio's Frankenpatent on Error Correction

written 13 days ago by Omics! Omics! by Keith Robinson

Well, here we go again. Pacific Biosciences launched yet another patent lawsuit towards Oxford Nanopore at the end of September, and already the hounds are baying for me to look at the patents -- which I've foolishly established a reputation of doing. I will remind readers that, to use a construction that exasperates my son, I have no memory of these topics being covered during the time I was in law school. (said construction also works for divinity school, seminary, yeshiva, dental school, military academy, etc). Read more »

Dispatches from CDC AMD Day 2017

written 16 days ago by Omics! Omics! by Keith Robinson

I had the singular honor and pleasure of speaking this past Monday at the Center for Disease Control and Prevention's Advanced Molecular Detection(AMD) program's annual confab in Atlanta. Just visiting the CDC campus was already a bit magical -- along with the Kennedy Space Center and Cold Spring Harbor it's one of mythical places of human exploration to me. But to actually stand at the podium? Wow!I've collected below a bunch of separate mental threads, many of which probably should be expanded out to a full post in the future.Read more »

Use annovar to annotate variants

written 20 days ago by Diving into Genetics and Genomics

Annovar is one of the widely used variants annotation tools. It was cited for over 2000 times which is amazing. It annotates the variants in a tabular format which is easy to parse. Other tools such as VEP and VCFanno are alternatives.First download the annovar package (you will need to register and an email with downloading link will be sent to you)wget http://www.openbioinformatics.org/annovar/download/0wgxR2rIVP/annovar.latest.tar.gztar xvzf annovar.latest.tar.gzDownload the databasescd annovarperl annotate_variation.pl -buildver hg19 -downdb -webfrom annovar refGene humandb/perl annotate_variation.pl -buildver hg19 -downdb cytoBand humandb/perl annotate_variation.pl -buildver hg19 -downdb -webfrom annovar snp129 humandb/perl annotate_variation.pl -buildver hg19 -downdb -webfrom annovar exac03nontcga humandb/perl annotate_variation.pl -buildver hg19 -downdb -webfrom annovar gnomad_genome humandb/perl annotate_variation.pl -buildver hg19 -downdb -webfrom annovar cadd13 humandb/perl annotate_variation.pl -buildver hg19 -downdb -webfrom annovar clinvar_20170130 humandb/perl annotate_variation.pl -buildver hg19 -downdb -webfrom annovar cosmic70 humandb/perl annotate_variation.pl -buildver hg19 -downdb -webfrom annovar dbnsfp33a humandb/AnnotateFirst download the annovar package (you will need to register and an email with downloading link will be sent to you) only 5 columns are needed for input: chr, start, end, ref, alt.

Why Is LISP So Rare in Bioinformatics?

written 24 days ago by Omics! Omics! by Keith Robinson

LISP is one of the oldest computer languages and perhaps one of the most influential of the early ones. Some of the other well-known Eisenhower era languages -- Fortran, COBOL and ALGOL, have certainly left their mark, but LISP and derivatives such as Scheme or Common LISP certainly carries more cachet among "serious" programmers. COBOL has always been a bit of an easy joke and Fortran tends to mark you as old-school; use of APL (once a language of mine) would mark you as dangerously reactionary. ALGOL begat Pascal and Modula II and clearly had impact on the C syntax family of languages (including bioinformatics mainstays Python, Perl and Java) As I'll detail below, learning LISP has embarrassingly ended up stuck seemingly permanently on my future plans queue. But that's also because life never forced the issue: while LISP has certainly been used in bioinformatics (as covered in a review from 2016 ) , its mindshare in the community would seem to be very minimal.Read more »

Teaching Biology Evidence: Old or New?

written 29 days ago by Omics! Omics! by Keith Robinson

I've been toying over a week with writing something based on an interesting Twitter discussion started by Dr. Laura Williams (@MicroWavesSci) of Providence College pondering the best way to approach teaching molecular genetics (really, science in general) at the undergraduate level. In particular, Professor Williams wondered about the dangers of branding various key experiments with the names of the experimenters, such as Hershey-Chase or Meselson-Stahl. The risk she points out is that this can devolve into an exercise in memorizing names and dates without assimilating concepts, or conversely that some students will find the names more of a hindrance than a help. I'm going to play a bit with this, but I do emphasize that for her this is reality and for me it is a hobby (or perhaps a retirement fantasy, if I should ever actually retire). Or in other words, for the academic this is her industry but for this industrial scientist it is academic.Read more »

Infographic-style charts using the R waffle package

written 5 weeks ago by What You're Doing Is Rather Desperate by Neil Saunders

Infographics. I’ve seen good examples. I’ve seen more bad examples. In general, I prefer a good chart to an infographic. That said, there’s a “genre” of infographic that I do think is useful, which I’ll call “if X were 100 Y”. A good example: if the world were 100 people. That method of showing proportions … Continue reading Infographic-style charts using the R waffle package
