Hi everybody,
Quick question. In the attached images there is pronounced banding present in the outside the head in the EPIs and appears to be introduced by running 3dvolreg as follows:
3dvolreg -Fourier -1Dfile T0245.breathing1_vr_motion.1D -base 'T0245.breathing1+orig.HEAD[249]' -prefix T0245.breathing1.reg T0245.breathing1+orig.HEAD
++ 3dvolreg: AFNI version=AFNI_2011_12_21_1014 (Feb 16 2012) [64-bit]
Anybody know what it is and whether I can safely ignore it (I don're recall having seen anything like it before)?
Thanks,
Colm.
