Hello,
I preprocessed my rs-fMRI data with fMRIprep. This software applies high-pass (128s / 0.008 Hz), then it computes aCompCor components and saves them to a .tsv file.
Now, I am denoising the data with XCP-D (pipeline . In principle, I would use those pre-filtered aCompCor components in my XCP-D pipeline, but I’m concerned about excessive filtering.
Question: Applying high-pass filter and regresing out with CompCor is redundant or inconsistent? this is my pipeline: aCompCor + motion regression + high-pass filter (0.01 Hz) Interpolation + scrubbing (FD > 0.5mm) + smoothing (6mm FWHM).
