I have an fMRI data set made up of 500 slices, 5 slice for each volume, TR(repetition time)=3 s.
The stimolation task (only 1 task) is:
0-20 s --> ON
20-40 s --> OFF
40-60 s --> ON
...
480-500 --> ON
so the number of volumes for each semiperiod (ON or OFF) is not integer, because TR=3 s.
Which is the best way to analyze this data?
In particular, when I use 3dDeconvolve, how must be the 'stim_file'?
Thank you in advance for your kind reply.
