Hi Gwenaelle,
Thanks for that.
I'm writing direct to you rather than burden the forum with this...
We have 60 subjects, and there is no defined control group - we expect to
regress several different clinical and psychometric parameters between the
subjects to see what falls out.
With this in mind, do I have to make the template from ALL of the cases?
This looks like it would be a big and very long computational task. Is it
reasonable to make the template from a smaller subset, selected randomly? If
so, how many subjects do you think would be OK?
Did you go to the SF course? I see it was heavily attended.
Cheers
J
