¥ The experiment analyzed here in fact is more complicated
H There are 4
related visual stimulus types
H One goal is
to find areas that are differentially activated between these different types of stimuli
H We have 4
imaging runs, 108 useful time points each (skipping
first 2 in each run) that we will analyze together
o Already registered and put together into dataset rall_vr+orig
H Stimulus
timing files are in subdirectory stim_files/
H Script file waver_ht2 will create
HRF models for regression:
¥ cd stim_files
¥ waver -dt 2.5 -GAM
-input scan1to4a.1D > scan1to4a_hrf.1D
¥ waver -dt 2.5 -GAM
-input scan1to4t.1D > scan1to4t_hrf.1D
¥ waver -dt 2.5 -GAM
-input scan1to4h.1D > scan1to4h_hrf.1D
¥ waver -dt 2.5 -GAM
-input scan1to4l.1D > scan1to4l_hrf.1D
¥ cd ..
H Type source
waver_ht2 to run this script
o Might also use 1dplot to check if input .1D files are reasonable
