[MINC-users] label from 2 objects

[Mishkin Derakhshan]

Hi,
I have two .obj files, and I'm assuming one is completely contained
within the other. For example, a white matter surface and a grey
matter surface for a single hemisphere.
I'm interested in obtaining a mnc file that is a binary label that
contains all the voxels between the two surfaces.
My first attempt was to load things up in Display, scan the objects to
volume and then use 3D Fill to get all the voxels in between, however,
because the scanned objects sometimes touch on the volume, the 3D fill
area, is not contiguous ie. i have lots of holes that i would need to
fill manually.
My next idea is to resample my volume to a 0.1 mm^3 grid and then try
again, but I'm wondering if anyone has done something like this before
and has a better solution.

thanks,
mishkin
