Installation linux

Installing the relax dependencies

For RPM-based Linux distributions with access to the YUM installer, first install the relax dependencies with:

yum install python
yum install scons
yum install wxPython
yum install grace

If you do not have root access but are in the sudo group, you can type:

sudo yum install python
sudo yum install scons
sudo yum install wxPython
sudo yum install grace

The [Grace] software is used for visualisation of 2D data sets. Next the [minfx] and [bmrblib] libraries can be installed on all Linux systems by typing:

wget http://download.gna.org/minfx/minfx-1.0.5.tar.gz
tar -xzf minfx-1.0.5.tar.gz
cd minfx-1.0.5
python setup.py install
cd ..

wget http://download.gna.org/bmrblib/bmrblib-1.0.3.tar.gz
tar -xzf bmrblib-1.0.3.tar.gz
cd bmrblib-1.0.3
python setup.py install
cd ..

Testing the Python installation

Before installing relax, it is best to be sure that the Python modules are functional by importing them:

$ python
Python 2.6.6 (r266:84292, Oct 12 2012, 14:23:48)
[GCC 4.4.6 20120305 (Red Hat 4.4.6-4)] on linux2

>>> import wx
>>> wx.__file__
'...'

>>> import bmrblib
>>> bmrblib.__file__
'...'

>>> import minfx
>>> minfx.__file__
'...'
