Oops i just realized I only sent this to Bruce:
Thanks! It looks like this involves some manual intervention. Matt., I assume you're not manually making control points on 1000s of subjects (I imagine this is for the human connectcome project). Is your code public somewhere?
Cheers, Michael

sure, here's mine. Matt's is probably a lot more polished as they intend to run it on hundreds or thousands of subjects

Hi Bruce,
Sounds cool, I'd be very interested in checking out the script.
Cheers, Michael

It's a bit complicated as you need to intensity normalize and register the hires volume to the surfaces first. I have an example script if anyone is interested, but no one has used it yet but me I don't think (unless Matt Glasser has gotten his version working, which on second thought he probably has)

Haven't tried it on the aseg yet, but if you upload a sample dataset I could see how hard it is. cheers Bruce On Mon, 14 May 2012, Joshua Lee wrote: > Dear Freesurfers, > > Over the last years, MR imaging technology hasimproved such that sub 1-mm > isotropic scans can be obtained with good signal to noise characteristics. > For example, our lab uses 0.7mm isotropic structural MR images.
