I've come across a curious normalization issue using the "normalise to
MNI" option in SPM8 (with recent updates) on partial-coverage EPI
scans. Segmentation, coregistration, and template creation seem to
work ok (see struct_c1_exampfun.png).
Applying the flow field to the segmented structural image seems to be
fine. However, when I apply the flow field to the functional data, I
get the strange warping attached (see avg152_mwc1_swf.png). This came
up at least once previously on the list, but I didn't see any replies:

Have others run into this issue? Any idea what this might be due to,
and (even better) possible suggestions for ways to fix? Thanks!
