Installation

Installation from the Python wheel

A Python wheel is provided for an easy installation. Simply download the wheel (.whl file) and install it with pip :

pip install --user wheel.whl

where wheel.whl is the wheel of the current version.

If you are updating PORTAL, you have to force the re-installation :

pip install --user --force-reinstall wheel.whl

Installation from the sources

Alternatively, you can build and install this package from the sources.

git clone git://github.com/pierrepaleo/portal

To generate a wheel, go in PORTAL root folder :

python setup.py bdist_wheel

The generated wheel can be installed with the aforementioned instructions.

Dependencies

To use PORTAL, you must have Python > 2.7 and numpy >= 1.8. These should come with standard Linux distributions.

Numpy is the only component absolutely required for PORTAL. For special applications, the following are required :

• The ASTRA toolbox for tomography applications
• pywt for Wavelets applications. This is a python module which can be installed with apt-get install python-pywt
• scipy.ndimage is used for convolutions with small kernel sizes. If not installed, all the convolutions are done in the Fourier domain, which can be slow.

Note : Python 3.* has not been tested yet.
