Hi Noah,
If you are trying to compare average head motion between groups,
then the question becomes how to compute the average head motion.
Note that when using afni_proc.py to process the resting state data,
it will output the average motion (both uncensored and censored) at
the end of the processing. Those averages come from the enorm
dataset, which is the Euclidean norm time series of the derivative of
the motion params.
