Hi all,
I was wondering about how to find a suitable order for modeling baseline in general (the option -polort in 3dDeconvolve). Is there a general rule about it?
In any case, when trying different orders, how can I operatively judge the goodness of my fitted data?

I am working specifically with a continuous run lasting 14 minutes (very long, eh?). I tried with -polort 1 and with -polort 2 and I obtained very different activation maps (keeping constant the threshold on the p value). Which is the right way of behaving in this case?

Thanks for your help!

Regards,

Silvia
