Hi Akiko,
The likely reason you can't post is that you're not a member of
caret-users. The subscriber list doesn't show a [EMAIL PROTECTED], which is
the address you're posting from (although there are some hidden addresses).
I've copied caret-users. A couple of things come to mind:
1) Your volume is rotated significantly off AC-PC line.
2) There are "bridges" connecting the cerebellum to the ventral
occipital cortex.
Create a zipped or tar/gzipped archive of your dataset (cropped
anatomical volume header and brik/img; params file; and spec file) and
upload it here:
http://pulvinar.wustl.edu/cgi-bin/upload.cgi
I'll take a look at it when I get a few minutes.

Hello,
I have been using Caret to segment brains and recently encountered a
problem of getting either "Hindbrain segmentation error", or
segmentation that is missing most of the structures (esp. posterior part).
We have been using FSL's susan_smooth twice on structual, and also
correcting for signal intensity inhomogeneity before loading into Caret,
and these procedures seem to give us good results in segmentation in the
past. However, there is one brain (both hemispheres) that does not go
through. During the segmentation, I usually set the peaks a little bit
to the left, but it gives the same errors. I have also tried different
peaks, and low/high thresholds for hind brain segmentation.
Any idea what might be going wrong, and any suggestion for the better
segmentation tips?
Thanks in advance, Akiko
