Ming,
I tried affine only normalization by setting "non-linear frquency cut
off"="inf" Alternatively, you can try "non-linear iterations=0", but I
haven't tied that.
I'm also wondering about the unit of period in "non-linear frquency cut
off". I appreciate if someone can help me with this. Is this given by
the number of voxels so that if I were to normalize with t1w template
(91x109x91), having cut off frequency=25 is 4x5x4 harmonics of cosine
functions?
thanks,
Hedok
