pyrfu 2.2.6

Python Space Physics Environment Data Analysis

The Python package pyrfu is a software based on the IRFU-MATLAB library to work with space data, particularly the Magnetospheric MultiScale (MMS) mission.

It is distributed under the open-source MIT license.

Full documentation can be found here

Instalation

The package pyrfu has been tested only for Mac OS. pyrfu requires FFTW3 . Install FFTW3 using homebrew and set temporary environmental variables, such that pyrfu finds fftw:

brew install fftw
export DYLD_LIBRARY_PATH=/usr/local/lib
export LDFLAGS="-L/usr/local/lib"
export CFLAGS="-I/usr/local/include"

Using PyPi

pyrfu is available for pip.

pip install pyrfu

From sources

The sources are located on GitHub:

https://github.com/louis-richard/irfu-python

1. Clone the GitHub repo:

Open a terminal and write the below command to clone in your PC the pyrfu repo:

git clone https://github.com/louis-richard/irfu-python.git
cd pyrfu

2. Create a virtual env

pyrfu needs a significant number of dependencies. The easiest way to get everything installed is to use a virtual environment.

• Anaconda

You can create a virtual environment and install all the dependencies using conda with the following commands:

pip install conda
conda create -n pyrfu
source activate pyrfu

• Virtual Env

Virtualenv can also be used:

pip install virtualenv
virtualenv pyrfu
source pyrfu/bin/activate

3. Install the package via the commands:

python setup.py install

5) (Optional) Generate the docs: install the extra dependencies of doc and run the setup.py file:

pip install pyrfu
python setup.py build_sphinx

Once installed, the doc can be generated with:

cd doc
make html
