We also have a number of these probability maps constructed on the
surface, and I think they are now part of the distribution (is that true
Nick?). We have maps for BA17, 18, 1, 2, 3a, 3b, 4a, 4p, 6, 44, 45, area MT
and entorhinal cortex (the last of which we built ourselves from ex vivo
MRI). Note that the surface maps are much more accurate than the volume
maps, so you are better off using them as opposed to taking say the map in
Tal coords and mapping it to your subject.

We have a program called mri_vol2surf which does the projection, and tksurfer
which does the visualization. But you need to make sure that the surface and
volume are in registration. This is done with tkregister2. Usually, the
volume you are sampling to the surface and the surface itself are from the
same subject.

Dear Freesurfer Community,
I am quite new in freesurfer, getting just acquainted with the tools.
What I am currently trying to do is, projecting 3-D voxel data (i.e.
postmortem probability maps of Prof. Katrin Amunts and Prof. Karl Zilles in
Research Center Juelich -Germany) onto the cortical surface.
For the time being, I assume that both types of data are registered to a
reference space (e.g., Collin27-brain).
Which functions I would/could need for the calculations and visualization?
Which data format(s) is/are required in order to be able to make use of the
available freesurfer functions?
Any guidance and all tips are very welcome :-) And sorry for any
inconvenience using the terminology!
Thanks, Eylem Kirlangic
