Hi ,
This is somewhat related to my previous question. I want to compare the same
16s/32s on/off block fMRI data with 3 different models. Model1: Block-On=16s
, Model 2: Block-On=10s and Model3: Block-On=4s. Each convolved with Double
gamma Hrf. I want to compare the PE values across these 3 models in
different ROIs. The PP heights of these three models are different. Would i
need to rescale each regressor to the same height?
I would run 3 separate analysis on the same data, however is there a faster
way i can do this?
Thanks!
-Vish
