Hi,

I have a question about regressing out the motion parameters produced by 3dvolreg. It seems there are several ways to do this:

1. Using the -ort option in 3dBandpass
2. Using -vector in 3dDetrend
3. Using -stim_base in 3dDeconvolve
etc

Do these all perform effectively the same operation? Is there any advantage to removing the motion components earlier on in the pipeline, i.e., prior to 3dDeconvolve? If you do regress out the motion parameters in 3dDetrend/3dBandpass, is it completely redundant to then include them as nuisance regressors in 3dDeconvolve?

Thanks!
Sam
