I see. Getting FS working is going to be a case-by-case thing then. For
holes extending into the ventricles you will probably need to fill the
hole in the wm.mgz to make the topology closer to what we expect it to be.
For the gliomas it depends on where they are

In some cases this is a hole in the cortex extending to the ventricle...in
others it 8s a low grade
glioma which substantially enlarges ....and distorts the cortex

Hi Matt
yes, we have done this a number of times but of course it depends a lot
on the details of the abnormality so it is hard to give generic advice

Basically, this

However, I wonder if
