Installation
============

NPAT is available through the `Python Package index`_, which allows installation using Python's standard command line utility `pip`_.  Assuming Python and Pip are installed already, you can install NPAT with the command::

	pip install --user npat


or::

	python -m pip install --user npat


If you'd like to install the most recent (unreleased) version of NPAT, you can clone the NPAT `github`_, and install by either running ``python -m setup.py install --user`` or ``make install``.

Troubleshooting
---------------

NPAT should download about 1GB of nuclear data during setup, however if this download fails for some reason the databases can be downloaded by downloading the `setup`_ file and running it with the command::

	python setup.py install --user

If this fails, you can alternatively download npat as a .zip file from `dropbox`_ and unzip it into the appropriate site-packages directory.  If you're unsure where that is, the following `StackExchange`_ is a useful reference.
