As an Ensembl Outreach Officer I get asked a lot of questions. Mostly questions about our data and interfaces but occasionally, just occasionally, something a bit more blue sky.

A couple of weeks ago I was teaching an Ensembl Browser workshop at the Erasmus MC in Rotterdam. I was just explaining that all our data and code was completely free to use, open source and open access, when someone asked me: Why? What’s in it for you?

Why indeed? Why are there forty people dedicated to producing this project? Why do our funders give us all this money to do it? Why do we just give it all away for free?

Why do science at all?

The fundamental answer varies for all of us. Things like improving people’s lives, curiosity, discovery. These are the motivations that got most of us into careers in science at all. Ensembl may not be directly be doing research, but we’re enabling it.

The Economic argument

There’s also an economic answer – in terms of time, money and infrastructure. How much does it cost to annotate a genome? To do pairwise sequence comparisons of over a million genes? To annotate variation? To make regulatory data meaningful? How much does it cost to put this into an easily accessible format? How much does it cost to regularly update this with new data? How many terabytes of memory do you need to actually store this stuff?

Even though these are non-trival costs, infrastructure projects in bioinformatics are about saving money overall. Funders and scientists understand that lots of different labs need the data and the analysis that we produce. However, it would be horribly inefficient if each lab who needs the resources we provide had to produce it themselves, repeating work that somebody else has already done, spending money that has already been spent, spending time that they could be spending doing other experiments or doing other analysis. Therefore, we have a system where we do it for them and put it all up where they can find it. Nothing’s repeated. Plus, our experience, expertise and raw computing power means that we can do it more cheaply and quickly than most labs can.

Free to be serendipitous

By giving the data away for free, we allow serendipitous discovery. If we charged people to use Ensembl in some kind of per-use manner, then they’d only use Ensembl to look for things they knew they were looking for. Yet we know that much of scientific discovery occurs when people accidentally stumble across things, like Alexander Fleming’s mouldy Staphylococcus plates. By allowing people to browse Ensembl freely, without worrying about costs, they may stumble across the tool or data that will be exactly what they need.

A relatively big group of people work for the project and they don’t work for free. But overall, we save the research community money by enabling science to be built on our foundation.

So, the answer to “what’s in it for me?”: I work for a project that makes science happen as efficiently as possible.

  • Are you new to Ensembl and want some help on using the browser?
  • Have you used Ensembl before, and want to learn more about it?
  • Do you want to get data quickly using BioMart?

These Online Tutorials are helpful for beginners looking for pointers in browsing their favourite gene, variation or region of interest, or those looking to further develop their skills.

The Quick Tour. A good place for beginners, this gives a brief overview of the kinds of data you can find on Ensembl and where to look for it. There are also links throughout to more detailed tutorials. This is only a thirty minute course so don’t expect to be an Ensembl expert at the end of it!

The Beginner’s Ensembl Course. This is a good place for beginners, or for Ensembl users wanting to expand their knowledge about the browser. In total, this three-hour overview covers Ensembl genes, variation, comparative genomics, and regulation. You’ll learn where the data comes from and how to access it.


Video Tutorials. These videos range from 2 minute clips to 20 minute overviews on a particular topic in Ensembl. This is a good place for anyone from beginners to frequent users to increase knowledge and understanding of the wealth of data and resources Ensembl provides. All of our videos are found on our YouTube channel, and our YouKu channel if you’re accessing Ensembl from China.

Looking for more? Have a look at our tutorials page.

Don’t forget, we run customised browser and API workshops if you want an Ensembl expert to take you first-hand through the site.
