If you’re new to next gen sequencing, figuring out what to do with your results can be a daunting process. Luckily, you’re not alone—plenty of people have been in your shoes, and there is tons of information about data analysis out there. Here are some free resources you can use to get up to speed…
Next gen sequencing is a powerful technique, one that now lies at the heart of many scientific projects. This power comes with some special challenges, however, and by recognizing them you can ensure that your NGS results are robust. No one wants to publish findings that other scientists fail to replicate, but unfortunately it happens…
You’re applying for your first tenure-track position, and you’ve heard that your dream department uses something called the h-index to decide who will get interviews. It’s an increasingly common scenario: institutions are now regularly using the h-index to help make hiring and promotion decisions, especially when they have to screen many applicants. For that reason,…
You’ve got an advisor, you’re done with classes, you’ve finally passed your qualifying exams and your dissertation project is underway. Life is looking good, but it’s not too early to start thinking about how to tackle your dissertation. Chances are this is the biggest writing project you have ever undertaken, so breaking it up into…
The NIH grant that you are working on only gives you five pages to describe your research strategy. You’re wrestling with a research report for Science that has a maximum word limit of 2500. And the abstract for the conference you’d like to speak at this spring only allows you 300 words to summarize the…
In my previous article ‘Choosing a scripting language for next gen sequencing: Python, Perl, and more’ I discussed several of the more common programming languages used for next generation sequencing and things to consider when picking which one to learn. But now that you know WHAT you want to learn, HOW do you go about…
Large amounts of data? Check. Repetitive tasks? Check. If you work with next gen sequencing data, you have probably already realized it’s a good idea to learn a scripting language. But learning a programming language is a major endeavour, and with lots of languages available how do you decide which one to study? And once…
The Rise and Fall of the 454 Sequencer The GS20 454 sequencer, released in 2005, was the first next-generation DNA sequencer to hit the market, and its feats quickly dazzled the scientific community. As new sequencing platforms proliferated, however, many researchers opted for less expensive options and 454 market share fell. About a year ago,…
What do these three seemingly disparate studies have in common? After publication, the high-profile findings in each one were questioned due to the presence of batch effects. Batch effects are ever-present and insidious in science, so as researchers we need to always be on guard against them. Keep reading for a run-down of how they…
You’re about to start that big project you’ve been dreaming of for years. You’ve identified a potential miracle compound and want to figure out how it affects gene expression. But how are you going to do it: with next gen sequencing or a microarray? Especially if you are new to this area of research, the…
Whole genome sequencing (WGS) is becoming increasingly common. Doctors now routinely order it for patients with puzzling diseases. The NHS (National Health Service in the UK) has declared that it will sequence 100,000 genomes over the next few years. Increase WGS…increase ethical questions The direct-to-consumer company 23andme has been experimenting with whole exome sequencing (WES), and another company, DNA…
