Hello,

I have a question including different durations for each block in an fmri run using 3dDeconvolve (or even afni_proc.py)

The run has 10 trials. 8 trials are 15 seconds in duration.

For this particular run, the majority of the blocks are of the same duration, 15 seconds. For 2 trials, there was a machine malfunction where the stimuli was too short,12 seconds,and too long, 17 seconds. We want to include those 2 trials and model them with the correct duration. Using BLOCK, we cannot do this since it has a fixed duration for each block in a run.

Looking at the help for 3dDeconvolve, would the -stim_times_FSL option work in this scenario. If so, is there an option to incorporate this into afni_proc.py?

Thanks.

Michael
