Hello —

It's my first time working on the resting state data, and I would like to ask about which file to use as the ort input.
To note this first, I'm not using afni_proc.py (sorry!) and using the output from fmriprep and have deobliqued and blurred the data as a preprocessing step.

I put my motion parameters in a 1D file where each column has each parameter's info, which I usually use in 3dDeconvolve. Can I use this 1D file directly in 3dTproject, or should I run 3dDeconvolve to create the x matrix (probably with x1D_stop option)?

I tried both and they appear similar but different — I would love to know which is recommended/what is the difference.

Also, should I detrend the data using 3dDetrend before using 3dTproject?

Thank you!
