# Define the chemical shift relaxation interaction.
value.set(-172 * 1e-6, 'csa', spin_id='@N*')
</source>
==== Let us try to execute ====
Now add the following lines in "sam_script.py"
<source lang="python">
# Execution.
############
# Change some opt params.
# COMMENT THESE OUT FOR REAL CALCULATION. THIS IS ONLY TO SPEED UP THE PROCESS IN ERROR SEARCHING.
dAuvergne_protocol.opt_func_tol = 1e-5
dAuvergne_protocol.opt_max_iterations = 1000
# Do not change!

</source>
Now we are just going to try this AND using a log file
<source lang="bash">
relax sam_script.py -t log.txt
</source>
==== The whole script file looked like this ====
