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
