Hi Dr. Klein,
The Van Essen Lab has a tutorial showing how to register Freesurfer
generated surfaces to the Van Essen macaque atlas. The same process
could be applied to the human colin atlas. See the link to Caret User's
Guide and Tutorial Part 2 at http://brainmap.wustl.edu/caret.
The applicable tutorial is #11:
REGISTRATION OF FREESURFER MAPS TO MACAQUE ATLAS MAPS USING CARET
PART I. FreeSurfer to Caret file conversion
PART II. FLATTENING AND SPHERICAL MORPHING
PART III. DRAWING LANDMARKS FOR REGISTRATION WITH ATLAS
PART IV. Registration of new data sets to atlas left or right hemispheres
This tutorial describes how to take FreeSurfer-generated surface maps
and associated fMRI data from individual hemispheres and register
(deform) these maps to a surface-based atlas generated in Caret. ... The
atlas data set is from a surface-based atlas (Macaque.F99UA1) generated
in the Van Essen lab and includes cortical areas, connectivity patterns,
etc. ... Once the surface-based registration process is finished, data
can be mapped in either direction (e.g., from the atlas to the
individual, and vice versa).
David Van Essen has used Caret's mapper to map functional/activation
data to surfaces imported from Freesurfer, but this requires steps to
align the volume and surface grids which are not documented.
I suppose it would be possible to generate surfaces in SureFit; somehow
import the resulting surface to Freesurfer; and map/register in
Freesurfer, but I'm not aware of anyone who has done so.
Other posts to this thread also would be of interest to the SureFit
mailing list ([EMAIL PROTECTED]).
Thanks,

Hi Johannes,
sorry, we don't have anything for converting from one to the other, but I
think David Van Essen might, as I gave him and Heather Drury our surface
formats some years ago for this purpose. There was also a poster at HBM
comparing the two packages by a group at the NIH, so they might have tools
for doing so.
Sorry.
Bruce

Hi everyone,
has anybody successfully converted surfaces and activation data between
Freesurfer and SureFit? Does that work reasonably well?
Thanks
Johannes
