Hi Geena,
Yes, the modern one just applies the modern version of make_random_timing.py.
I would think that in your case, the modern version might still be reasonable to apply, as you would be able to specify the min/mean/max of the ITIs, which would presumably tend to be long.
The created 3dDeconvolve script will use BLOCK, but you might just pipe that through a "sed" command to convert BLOCK(A,1) (for whichever A) to the appropriate MION response function.
Try setting that up as you see fit, and then I can comment more directly on the commands you are trying. If you also post the -stim_times lines of the 3dDeconvolve command, along with your preferred MION function, I can suggest how to convert it.
