Hi,
I am looking for a
method to test for differences in the BOLD-time course between two groups.
Ideally, I would like to test for differences in time to peak, full width half
maximum, time to onset etc.
Perhaps FLOBS can be
used to do this. I have one condition only: when I use FLOBS using the default
functions, I can ask for 3 contrasts (one for each regressor) and for the F-test
giving me a linear combination of the 3 functions.
My question now is:
how can I use these FLOBS results at second level? Are there ways to
compare the best fit of the BOLD response between group A and
B?
Is there perhaps a
way to extract measures such as time to peak, fwhm etc, and then use these at
second level?
Thanks,
Serge.
