Dear Fs experts,
I am running a longitudinal dataset through the longitudinal pipeline, and noticed that for one subject, although we kept everything the same (sequence, coil etc) the two timepoints' brainmasks look different: timepoint one (in the attached snapshot, gs_tp1) looks as if it has been smoothed, compared to timepoint two (gs_tp2). I have checked some other images from this subject, and the same seems to occur for orig.mgz, but not for rawavg.mgz.
Any idea on what could be causing the difference would be greatly appreciated.
Thanks in advance, Irene
