Hi,
I would like to compare the mean head motion between two groups.
Just to clarify the values found in the mcprextreg file: 1. Do the six columns represent translationX, translationY, translationZ and rotationX, rotationY, rotationZ?
2. Are the values found in each time-point (i) absolute, i.e. the absolute difference in displacement between this time-point and the middle time-point, or (ii) relative i.e. difference between consecutive time-points?
Thanks, Newfei
