Hiya, no we actually haven't - yet. They have only been demeaned. Sorry for my poor understanding of this issue, but would I need to do the same for the confound variables (CSF, WM, and global mean)?
Is this a particular requirement for randomise, or does this need to be done before feat (and before afni's 3dcluster) as well?
Thanks for your input - I am quite glad to be pointed to errorenous steps in our data processing stream.
Cheers,
Torsten
