Hello!

I was wondering if instead of the options listed for extracting the ROI time series and detrending (from [afni.nimh.nih.gov]), it would be alright/equivalent to run 3dDeconvolve to remove the trend and account for motion, collect the residuals, then use the residuals for ROI time series extraction and proceed as outlined? Sample script below

Thank you for your time!
