Hello,

I am trying to perform duration and amplitude modulation together, and according the the 3dDeconvolve help file, the best option for this is the -stim_times_AM2 option. My main question is in relation to the ordering of the stim_times files when I specify this part of the 3dDeconvolve command:

-stim_times_AM2 1 Timing_Files/Cond1.txt 'dmBLOCK(1)' -stim_label 1 Cond1 \
-stim_times_AM2 2 Timing_Files/Cond2.txt 'dmBLOCK(1)' -stim_label 2 Cond2 \

Assuming I have 6 runs, should my Cond1_timing.txt file look something like this (where I have the onset times of the stimuli and their corresponding durations)?
