Hi Freesurfers,
I have tried to obtain a flat surface as described by the upper part (full cortex) of the following page:
http://freesurfer.net/fswiki/FreeSurferOccipitalFlattenedPatch
However, I failed to load the results in freeview (it took forever), nor can I read in matlab with read_surf. The error in matlab is as following ====== Error using reshape To RESHAPE the number of elements must not change.
Error in read_surf (line 77) vertex_coords = reshape(vertex_coords, 3, vnum)' ; ====== Thus I suspect in the newly generated surface, the number of vertices in the header does not meet that indicated by the data. I did sth wrong.
Questions: 1 Is this webpage still up-to-date or I shall try something new to flatten the surface? 2 Probably there are "frequently made mistakes" during my manual process, would you please give me a hint? I my case afterwards mris_flatten took 2-3 hours.
btw: the inflated surface is OK either checked by freeview or matlab.
best Peng
