I'm looking for a bit of clarification/help using the PPI-Pipeline from here [
afni.nimh.nih.gov]
For starting the PPI pipeline I should not use 3dDetrend initially but instead use 3dSynthesize on my input dataset to making a dataset of my baselines/regressors of no interested then use 3dcalc to make a timeseries with those removed? I would believe this covers the detrending as my polorts were removed as effects of no interests in 3dSynthesize.
From here i can extract my ROI with using 3dmaskave, and continue with deconvolution of the time series
