Hello again! I'm having some difficulty figuring out which sub-brick is which in the output functional file of my AM Regression script. I'm looking at the effects of Age of Acquisition ("AoA") on the BOLD signal amplitude in stroke patients with aphasia who performed an object and action naming task in the scanner. The script goes like this (with asterisks in place of patient initials):


3dDeconvolve -input **_AllEpis+orig -num_stimts 2 -polort 2 \
-stim_times_AM2 1 AoA*ObjectTimes.1D GAM -stim_label 1 Objects_AoA \
-stim_times_AM2 2 AoA*ActionTimes.1D GAM -stim_label 1 Actions_AoA \
-concat Runs.1D \
-full_first -fout -tout -nobout \
-bucket Func_**_AoA -fitts Fit_**_AoA

The sub-bricks in the output file are:

0 Full_F-stat
1 Actions_AoA#0_Coef
2 Actions_AoA#0_Tstat
3 Actions_AoA#1_Coef
4 Actions_AoA#1_Tstat
5 Actions_AoA_Fstat
6 Stim_2#0_Coef
7 Stim_2#0_Tstat
8 Stim_2#1_Coef
9 Stim_2#1_Tstat
10 Stim_2_Fstat

I believe that the first two sets are the mean activations for objects and actions, respectively, and that the two "Stim_2" sets refer to the actual effects I want, first for objects, then for actions. Is this correct?
Thank you!
Yours in modulation,
Whitney
