Hi Jason,
Sounds like some catastrophic problem. First, are you using the atlas
target dataset cited here:
http://brainvis.wustl.edu/help/landmarks_core6/landmarks_core6.html
Second, check your landmark border polarity.
Third, while handles are unlikely to cause holes in the cusrface,
they'll cause other trouble (i.e., inaccurate results), so you should
fix them.
If you toggle on the "Show first link in red" option in the Borders menu
and generate some captures of you landmark borders on the inflated
surface, it will help us figure out what is going wrong. Views like the
ones shown in the web site above are what we're looking for.

Dear Caret-users,
I have "successfully" warped a set of individual subject right
hemispheres to the PALS sphere. Problem? There is a huge whole in each
of the deformed images around the central sulcus. In the inflated
brains, the image looks "scrambled" in a portion of the central sulcus.
Is this a handles issue? I do not recall having any existing handles
in this region. Second, when the deform process was running, it said
that I had roughly 200 cross-overs. What is a cross-over and is that
related to the above problem? Thank you. Jason.
