Hi Ziad,

Thank you for your answers!

I tried to use "MapIcosahedron" to convert the thickness dataset into standard mesh, but I received this error:

** num_dim violation: num_dim = 2, yet dim[1] = 1
** num_dim violation: num_dim = 2, yet dim[1] = 1
-- Error MapIcosahedron (SUMA_MapIcosahedron.c:1211):
Failed to load lh.thickness.gii.dset


Could you help me understand what this means, and how I can fix this?
