Hello everyone:
I'm looking for help/input for ways to handle GLM design matrix regarding zscore and censor operations.
In the way our team understands, we see in it that AFNI applies the censoring to the fMRI data after subtracting the mean from baseline columns which are our 6 motion parameters. In this case, we don't have our columns centered around zero. We compared with data from computing zscore on our baseline parameters beforehand and it seems 3Ddeconvolve handles the matrix differently giving a non-zero centered matrix.
Any insight on how AFNI orders these operations using 3dREMLfit /3dDeconvolve would be appreciated.
Also, is this something where we can use any existing option to apply censor operation before/after the matrix adjustment?
Thanks!
