Dear Experts, I tried to extract vertex coordinates information from 'fsaverage/surf/lh.pial' file using matlab function 'read_surf', but I found that the coordinates returned by the function are different from what I saw in tksurfer, here are the screenshots:
The vertex index starts from 0 in tksurfer, so I select the second elements in matlab. Why is the result different from what has been shown in tksurfer(also different in freeview)? Which one should I report? Is there any way to transform the surface coordinates to the MNI152 space? Thank you very much! Dong
