Hi there,

I have a question about where to apply GLM on the resting-stat fMRI data when I have a regressor.
Solution 1: Apply GLM after finishing all preprocessing steps of afni_proc.py.
GLM will be just 3ddeconvolve with only my regressor applied to the errts.subj.fanaticor+tlrc .
Solution 2: Modify the outcome of afni_proc.py (proc.subj) and add the regressor to the GLM step applied after volume registration. Then estimate the stat from the outcome of the GLM analysis.
What is the recommended approach? And what are other regressors should be included besides my regressor (motion, ventricle signal, …) in this case?

Really appreciate your help!

Thank you,
