External Email - Use Caution
Dear Dr. Fischl
Thank you for your reply. I was going through the same reference earlier. However, as per my understanding, this page talks about converting a single point on cortical surface to another space. What I want to achieve is to extract all the vertices from the cortical surface in some form of displacement vector field, where I have the 3 dimensional co-ordinates for all the vertices in a matrix. Once I have this matrix, I can then convert it into MNI or any other space as mentioned in the page. However, I am not clear on how to extract all of these vertices from the cortical surface in some sort of matrix. Can you recommend some way to achieve this?

want to map each vertex on
the surface mesh to its corresponding voxel in the volumetric atlas. Any
help how to go forward with
it?
