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?
