Hello,

Thanks for the advice. So I decided to run afni_proc.py and add regression steps, rather than do 3dDeconvolve separately. I used the regress_stim_times option and am getting a fatal error. I will paste most of the afni_proc.py script below as well as the fatal error below it. Please let me know what I'm doing wrong. Thanks so much!!!

cd ${EXPDIR}${SUBNUM}
afni_proc.py \
-subj_id $SUBNUM \

This is the fatal error: ** FATAL ERROR: '-stim_times_IM 1 stimuli/scan1to2NPB.1D' has 1 amplitude modulation parameters - not legal! [nopt=13]


My stim files are in this format:
156.767800:3.785400 198.038800:5.475900 545.896000:3.857900 28.026700:3.782000 508.694400:5.247900
where the first number is the onset and the second number 'married' to it is the duration of the trial.

Thoughts??

Thanks!
