Make sure you have followed the installation instructions. You will need Git, Python and the various Python libraries installed.
cd $HOME/Documents
If you get `The system cannot find the path specified`, and you are on Windows,
make sure you are running a **Powershell** shell, not the much older Windows `cmd` shell.
Make a new directory to store your work, if you have not already done this in the installation instructions.
mkdir nipraxis-work
Change your shell to that directory:
cd nipraxis-work
Next go to this page : https://github.com/nipraxis/first-validation
Click on the "Fork" button on the mid-top-right.
Accept the defaults and click on "Create fork"
You will find yourself at the page for your new Fork. In my case that is https://github.com/matthew-brett/first-validation but the address will have your username in it, rather than matthew-brett.
Copy the URL.
Clone the repository from the command line, by typing git clone at the
terminal and then copy-pasting the URL. For example, for me, that would be
git clone https://github.com/matthew-brett/first-validation but you need to
make sure you clone your own fork, with your own URL.
cd first-validation
python get_data.py
You should see something like this:
Saving files to "data" directory

You will see a different cache directory in the printout above. My cache
directory was /Users/mb312/Library/Caches/nipraxis/0.4/ but your directory
will be specific to you, and the current version of the nipraxis module.
If there are any errors, let us know.
Check the files are in the data sub-directory with:
ls data
You will see and extra file in that directory, called data_hashes.txt.
Next run the data validation script:
python first_validation.py
