Installing the relax dependencies

The python-devel and scons packages are only required if the C modules need to be compiled for your system.

  • Grace software is used for visualisation of 2D data sets.
  • subversion is only if you wan't to checkout the source code.
  • matplotlib is not a necessity, but is likely to be implemented later for extended plotting.

RHEL 5 and compatible distributions

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

yum install python
yum install python-devel
yum install numpy
yum install scipy
yum install scons
yum install wxPython
yum install grace
yum install subversion
yum install python-matplotlib

# We can manage python package installations with pip
sudo easy_install pip

If you do not have root access but are in the sudo group, then add a sudo before each of the above commands.

Minfx and Bmrblib

  1. Minfx
  2. Bmrblib
  3. mpi4py

Testing the Python installation

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

Python commands: Testing modules by importing them.

Checking out a relax branch

If you would like to play with relax branch rather than the main relax downloads, the Git program should first be installed.
You can see the different branches here.
First the relax sources can be checked out of the source code repository and the C modules compiled:

Using git

To check out the relax trunk using the git client, simply type: 

git clone git://git.code.sf.net/p/nmr-relax/code/ relax

Compilation of the C modules

For the R1 and R2 and relaxation dispersion analyses, the relax C modules must be compiled. This is done using the scons program, by simply typing: 

cd relax_trunk
scons

You must be in the base relax directory for this to work.

In addition, if you would like to compile the relax user manual via LaTeX, you can also use scons. See the wiki page manual.:

Add to path - C_shell / Tcsh

cd relax_trunk
echo "setenv PATH $PWD"':$PATH' >> $HOME/.cshrc

Restart the terminal, to load the new variables.

Start relax

Normal

# Normal
relax
# See help
relax -h
# In GUI mode
relax -g
# Execute script
relax -g

Test installation

Caution  After an installation you should really run an Installation_test.

Trouble shooting

The menu icons are missing in Linux.

On some Linux systems, the icons for the menu items are not shown. This was a decision taken by the Gnome developers at some point to keep the GUI minimal, though in recent versions this behaviour has been reverted.
If you suffer from this problem, to reactive the icons simply type in the shell: 

gconftool-2 --get /desktop/gnome/interface/menus_have_icons
gconftool-2 --type boolean --set /desktop/gnome/interface/menus_have_icons true

For GNOME 3 

# Get schemas
gsettings list-schemas
gsettings list-schemas | grep org.gnome.desktop
gsettings list-schemas | grep org.gnome.desktop.interface

# Get keys
gsettings list-keys org.gnome.desktop.interface 
gsettings list-keys org.gnome.desktop.interface | grep icon
gsettings list-keys org.gnome.desktop.interface | grep desktop

# Get value
gsettings get org.gnome.desktop.interface icon-theme

# https://wiki.archlinux.org/index.php/GNOME/Tips_and_tricks#Enable_button_and_menu_icons
# Since GTK+ 3.10, the GSettings key 'menus-have-icons' has been deprecated. Icons in buttons and menus can still be enabled by setting the following overrides: 
gsettings set org.gnome.settings-daemon.plugins.xsettings overrides "{'Gtk/ButtonImages': <1>, 'Gtk/MenuImages': <1>}"

# Check
gsettings list-keys org.gnome.settings-daemon.plugins.xsettings
gsettings get org.gnome.settings-daemon.plugins.xsettings overrides
