Intro to Bioinformatics

Intro to Bioinformatics

A short series offered by to members of Fred Hutch.

Overview of class

Class outline:

  1. Overview & remote server access
  2. Unix Shell I - overview
  3. Unix Shell II - scripting
  4. Version Control with Git
  5. Python I - syntax and data types
  6. Python II - building data structures
  7. Python III - writing a program

The class will be loosely following Bioinformatics Data Skills for the overview, unix, and version control sections. For the python sections, we'll be following our own curriculum, and referring to the Codecademy course as a reference and for additional practice with the concepts.

Prerequisites (connecting to the remote server)

You will need to bring a laptop to class to participate in the interactive sessions. However, all our work will be happening on a remote server to which we connect. Thus, it is vital that you ensure you can connect to this remote server before coming to the first class. (Specifically, make sure you can connect over the Marconi wifi network while on the Hutch campus.)

Connecting to the remote server requires the use of a terminal program, which let's us control a computer with text based commands. How you open the terminal program depends a bit on what operating system you are using. However, once you have the terminal open, you'll execute the following command

ssh <username>@rhino

Here, <username> should be replaced by your Fred Hutch network username. When this command runs, you'll be prompted for a password; use your Fred Hutch network password. You should see an informational message about the system, followed by a prompt that looks something like:


Try typing echo "it is working", and hitting enter. The terminal should print out "it is working" on the following line, and return a new prompt.

Next, try typing cd ~ and hitting enter. The terminal should return a new prompt.

If instead of this behavior you see something that looks like an error message, please notify us so we can help you get set up before the first class starts. (Note that you may get rhino01, rhino02 or rhino03 instead of rhino04; this is ok).

Below are the details about how you can get a terminal program with SSH, given your operating system.

Linux or OSX

Linux operating systems (such as Ubuntu) and Mac OSX come with SSH-capable terminals pre-installed. It should be straight forward to Google how to find and run the terminal program for your particular operating system.

Note that if you are using a Linux operating system, you may have problems with the wifi on campus, due to some unusual network settings. If you are unable to connect via wifi on your laptop, please ping the Fred Hutch computing Help Desk or Sci Comp to get you running.


Windows does not ship with an SSH capable terminal. As such, you will need to do one of the following:

Other prereqs

You should also be able to copy and paste text to and from the terminal. In Mac OSX, you can do this with Command-c and Command-v, as you normally would. On a Linux terminal, you need Ctrl-Shift-C and Ctrl-Shift-V. For Windows/PuTTY users, copying and pasting is accomplished using select and right click (see here). Make sure to try pasting and copying from the terminal before coming to the first class, so that you can copy and paste longer commands from the slides.

You will also need a GitHub account for the course. You can sign up for free here.

We also ask that you read the first two chapters of the book (particularly the first) before coming to class, as they'll give you some nice big picture context to work from.

Technical Notes

The slides (source code here) are written in a little extension of Markdown. After processing, the Markdown gets converted to a reveal.js presentation. HTML is rendered by the brilliant pandoc.

Source files are in the src/ directory, and have extension .mds. You can compile the file src/somefile.mds by typing make somefile.html, and open the file with firefox or chromium. You may need to install pandoc and some python related things to run this code. See the Makefile for some demonstration of make, if you're interested in using that as a replacement for building bioinformatics pipelines, or for customizing details of where files go and such in your fork. I may rewrite the build in SCons as well, so you have an example of that (and so I can work with this project more sanely).
