1. The translations are in mm. I don’t recall off the top of head whether the rotations are in degrees or rotations, but I believe that is documented in the release manual. (Or check the HCP Pipeline code).
2. RMS is based on a combination of both the translations and rotations. 3. Yes.

For the file Movement_RelativeRMS_mean.txt: 1) what's the unit of the number in it? 2) How was the number calculated? Does the RMS include only the 3 translations or all the 3 translations and the 3 rotations? 3) Is the mean taken along the temporal dimension? Thank you very much in advance.
