Hi Thomas, 1) We will be releasing version 2 of these data in the relatively near future, so you'll want to update to that.
2) Movement_Regressors.txt are in the output of the 4dfp tools: mmx mmy mmz degx degy degz dmmx dmmx dmmz ddegx ddegy ddegz (where the extra d in the front means derivative) _dt has means and linear trends removed from the above. Everything is corrected to the single band reference image SBRef (which is not a part of the time series), so there is no guarantee that the first row will be zero. I don't yet know how to use this mailing list either. Matt House can tell us more. Thanks, Matt.
