Author: Alex, October 19th, 2012

• Install the software

Base OS: Ubuntu 12.04.1

For Ubuntu repository versions:

sudo apt-get install ipython python-numpy python-scipy python-mvpa2 python-matplotlib git python-pip python-nibabel cython python-statsmodels python-sklearn python-skimage

For updated versions we can use Python Package Index (PyPI):

sudo apt-get install python-pip python-dev build-essential 
sudo pip install -U pip
sudo pip install -U ipython
sudo pip install -U cython
sudo pip install -U numpy 
sudo apt-get install build-essential gfortran libblas-dev liblapack-dev libumfpack5.4.0
sudo pip install -U scipy 
sudo pip install -U pandas
sudo pip install -U scikit-image scikit-learn statsmodels

Neuroimaging:

Nipy

sudo pip install -U sympy
sudo pip install -U nibabel nipype nipy
sudo pip install -U dipy nitime
