Greg, We’ve observed very similar issue in our Sinai non-compliant subject data. I briefly discussed the issue with Greg Burgess at WU, which didn’t lead to a conclusive solution. I think it may be worthwhile for us to put the troublesome motion correction data together and cross-check our examination methods to get to the bottom of this issue.

I’m assuming this is the 4D file which should be motion corrected, undistorted, and skull stripped. And that this file should be able to be used directly in stats processing without any further steps? However, I still see significant motion when viewing the 4D file in a cine view. The brain mask is constant, but the image under the mask moves. Did the mcflirt step not work, or is this normal?
