gedit test.py

Then we build the script onwards.<br>
We run relax repeatedly, to execute code. Then we write new code in the script, and run again.
relax test.py
When we are satisfied, one can then do like this.
Start relax
relax -g -t log.txt
Then do
User functions -> Script -> test.py
THEN do:
View -> Data pipe editor -> Right click on pipe -> Associate with a new Auto analysis
'''This should bring you to a window, where all settings have been set.'''
Set
* Relaxations dispersion models: ['R2eff', 'No Rex', 'CR72', 'NS CPMG 2-site expanded']
* Grid increements: 11 (For speed-up in test phase)
* Monte-Carlo simulations number: 5 (For speed up in test phase)
Then a quick click on spin.isotope function, and GO.
