Thanks Edward for your information. I am only familar with modelfree and just started to use relax since when I run modelfree using axially symetric models and got some problems. I only have data in 600 MHz and should only fit m0, m1-m5 and m9 in this case. I have tried to run modsel.py using these models, still error occurred as I posted previsouly. Not sure how to fix the problem.
