Hi,
In that case you will be optimizing everything, modelfree models and tensor,
at the same time, correct? So, the optimization will run not only on the
diffusion tensor parameters but also on the nature of the diffusion model
itself, is this it?

Subject: Re: AIC to select diffusion model
Hi,
I haven't found a way to make this totally obvious yet. To select
between these global models, you need to set up the global model. For
this, the diffusion tensor should not be fixed. If not fixed, then
the tensor is part of the model and all the model-free models for all
spins are linked together with the diffusion tensor into the one
global model. So for each data pipe containing the selected
model-free models, you just need to call the user function:
relax> fix('all', fixed=False)
I hope this helps!
Regards,
Edward

Hello everyone,
Can anyone help me on how to use AIC to select between diffusion models
instead of model free models (modelsel.py). Couldn't find any sample
script
that would give me a clue on this.
Best regards
