If you would like to play with relax branch rather than the main [http://www.nmr-relax.com/download.html relax downloads], the [httphttps://subversiongit-scm.tigris.orgcom/ SubversionGit] program should first be installed. <br>You can see the different branches [http://svn.gna.org/viewcvs/{{relax/ source|text=here}}.] <br>

=== Using subversion git ===To check out the relax_disp or relax trunk branch using the subversion git client, simply type:<{{#tag:source lang="bash">|svn co svn://svn.gna.org/svn/{{relax/branches/relax_disp relax_dispclone}}svn co svn://svn.gna.org/svn/relax/trunk relax_trunk</source> If this svn command does not work, try:<source | lang="bash">svn co http://svn.gna.org/svn/relax/branches/relax_disp relax_dispsvn co http://svn.gna.org/svn/relax/trunk relax_trunk</source>}}

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_disprelax_trunk

cd relax_disprelax_trunk

==Test installation = In multiprocessor mode ===<source lang="bash">set RELAX=`which relax`# Normalmpirun -np N+1 $RELAX --multi='mpi4py'# In guimpirun -np N+1 $RELAX --multi='mpi4py' -g</source>where N is the number of slaves {{caution|After an installation you have.
