For each section of the tutorial, there is a subfolder containing the necessary source files, plus one subfolder, data, containing the data files. To follow along with the tutorial, do the following:
Create a folder to work in.
Unpack the tutorial files into the folder.
At the beginning of each section of the tutorial:
Set default to your tutorial folder.
Copy the sources for that current tutorial into the your working directory, like so:
$ cp -r tutorial1/* ./
