Hi,

I'm running an experiment where I have two 12-min runs, and then I concatenate them (which is my first step in preprocessing). This results in a run that is 1435 seconds long. AFNI's 3dDeconvolve tells me to use a polort of 10 (which matches the formula of t/150). 10 seems very, very large... should I be using a polort of 5, since it's really two runs combined and not really one long run?

Thanks,

Jodi
