Dear list,
I want to do some statistics at the group level, hence I have to work
in the MNI space. However, on inspection of the normalization results,
I see that the subjects' normalized anatomicals don't match well, and
actually that they don't match the MNI template well (which is why
they don't match well...). I believe I'm using the recommended steps:
segment, make sure origin is close enough to AC, then use segmentation
parameters to estimate non-linear warping parameters. I attach here
results for 2 subjects: T1.png is the bias-corrected anatomical for
the first subject; normalizedT1_vs_templateT1.png is the result of
normalization compared to the MNI template. Same for second subject,
with _2 at the end of the filename.
Is this kind of result expected, or is there clearly something going
wrong (that's my hunch)? does any have an idea of what I should do to
make it better?
- Julien
