I have a question regarding an approach discussed on an earlier thread:

>My plan was to run 3dDecon with all the event regressors (200 in my case) and just output the coefficients (not all the model stats).
In order to do this analysis, would something like this work to get the betas?
3dDeconvolve -input s11_norm+tlrc \
-polort 7 \
-num_stimts 4 \
-stim_file 1 FAtimes.1D -stim_label 1 FA \
-stim_file 2 FAtimes.1D -stim_label 2 FF \
-stim_file 3 FAtimes.1D -stim_label 3 NF \
-stim_file 4 FAtimes.1D -stim_label 4 MF \
-bout \
-bucket s11_betacoefs
Each 1D file would have 1s at TRs that matched its condition, and 0s at the other TRs.
thanks,
Lesley
