hi Rick

Thanks for the quick response!

I agree that it is not a lot of stimulus per class. and actually it's worse because the stims are presented for 2 s and I guess I had added 1s as -post_stim_rest. The design is 29 color patches and the idea is to correlate the response to each color with some external variables (I don't know which ones as I am only helping out with the timings, or at least trying to--I think they are like personal preferences and the like).

Of course, I kind of imagine that the differences in BOLD between the stimuli is going to be small. Perhaps they could use fewer colors. In the meantime, we'll see about adding a few more minutes, but if not then they can go with what they have.

thanks so much for your help, and for make_random_timing.py--it's a great program.
