Thanks for this information. There are a couple preprocessing steps that I want to look at (especially filtering using 3dFourier) and want to think through the polort value (we are using the number of runs right now, but it seems that since we have long runs [~8 minutes], we should use a larger number). It is good to know that the setup is correct for the timings though. which will make evaluation of the results more trustworthy.
Best,
Wil
