Hi Mishkin
it depends what you want to do. We do have some tools (mostly Koen's) for generating cortical models from ex vivo data, but nothing really for subcortical segmentations. The high resolution actually doesn't help as you can start to see structures like intracortical myelin bands that we don't segment. We have some tools for using the highres data to adjust the surface models that could benefit, but they aren't ready yet.
cheers, Bruce

Hi, I have three questions regarding some postmortem data at high resolution (0.35 mm^3 isotropic).
- A question was asked about the possibility of using postmortem
scans in freesurfer back in sept 2007 and Bruce said:
Not easily, although we have some tools for doing this. They aren't
packaged and distributed though. Any updates?
- Is there a way to take advantage of this resolution and not
resample to the 1mm^3 grid?
- I only have one hemisphere. I am trying to flip the hemisphere to
create a whole brain that can be used as input, but seeing as most of the pipeline splits things up into two hemispheres, is there a way to run Freesurfer with just one hemisphere from the start?
