Hi Allison - There's no quantification of motion built in right now, although we're looking into this issue and perhaps it'll be included in a future version. You could look at the transformation matrices from eddy_correct (in dmri/dwi.ecclog) and quantify the frame-by-frame motion from that. Motion would be more catastrophic for the FA/MD/etc values than for the tract reconstructions themselves.
