Hello,
We're trying to use FLOBs to optimize the HRF for the rat fMRI data. According our understanding, the individual HRF can be calculated by pe1*h1+pe2*h2+pe3*h3, where pe is parameter estimate and h is FLOBS basis functions. Could we average these HRF between subjects to get an HRF model generalized for the population? If we're interested in the double gamma function specific for our subject population, is it valid to fit the averaged HRF with double gamma function?
Thank you,
Pei
