Hi Freesurfers
I have a few questions about gammafit flag in mkanalysis-sess command and I appreciate if you could respond whenever you had time. -How should we decide which function is best to apply on hemodynamic response signal? I have used both spmhrf and gammafit and I see slightly different results. -Does Freesurfer has a default function that applies on hemodynamic response signal if I don't use these flags? -Where should I get gfdelta and gftau from?
