Hi FSL users -
I must admit that I have very little a priori justification for using a
particular convolution shape for specifying my statistical model. I was
wondering if anyone could give me some help on weighing the relative merits
of using a gamma versus a double-gamma HRF or perhaps even one of the other
convolution shapes. I have used AFNI before so I am familiar with the use of
a FIR convolution as well, though given the additional work needed to recover
a single percent signal change statistic from a FIR convolution, I think I'd
prefer to stick with a one of the others for now.
thanks,
Ed
