Hi Edward. You asked to change the order of model names, after the year. I guess that you mean to change these files: gedit ./specific_analyses/relax_disp/variables.py ; gedit ./user_functions/relax_disp.py ; gedit ./lib/dispersion/__init__.py ; gedit ./target_functions/relax_disp.py ; gedit ./specific_analyses/relax_disp/api.py ; Is the meaning: CPMG - After year R1rho - After year Best Troels Emtekær Linnet
