Roland,
If your partial hemisphere does not include the anterior commissure,
it will probably be important to DE-select the Disconnect Hindbrain,
Disconnect Eye and Skull, Cut Corpus Callosum, and Fill Ventricles
options, as these rely on stereotaxic coordinates relative to the AC.
We don't have a lot of experience with segmentation of partial
hemispheres using Caret 5.x, so let us know if you encounter problems.

Hi Roland,
In Caret5, you proceed with segmentation of a partial hemisphere
just as if you had a full hemisphere (Volume Menu:SureFit
Operations (Segmentation). At the very last step, when you
generate surfaces, a dialog will query you for partial hemisphere
padding. We no longer save the padded volume.

Hi,
I just wanted to segment a partial (occipital) hemisphere which
used to be a
lot easier than segmenting an full hemisphere and is enough for my
purposes.
Unfortunately the tutorial doesn't mention how to do this with
caret and I
didn't find any options to tell the surefit in caret to assume
partial hem.
and pad the anterior. The Volume->Segmentation->Pad Volume didn't
have a
visible effect.
Is this option still hidden somewhere?
Regards,
Roland
