Hi Taha

none that I can think of. The medial wall is pretty substantial region though - I am more concerned about your subject with only 53 vertices in it. You can visualize it by loading the ?h.cortex.label onto the inflated surface. Everything not in the label should be set to 0


cheers

I see now, thanks for the answer. If I may, is there any particular reason why 
such a disparity between
two subjects, is this due to anatomical variability between individuals? I was 
surprised by the 9,000
values that was missing.

      The entire medial wall has thickness values of 0 because there is no 
cortex there. There
      needs to be a surface in that area because we need a closed surface.

      Hello All,
Quick question, I ran recon-all with the qcache option and after converting the
?.thickness.fsaverage.mgh to an ascii text file via mri_convert I am noticing 
some vertices
have 0mm thickness and it varies, for example, one subject had 53 vertices 
labeled as zeros
while another had over 9,000 vertices. Is there a method I can use to have a 
thickness value
for each of the 163000+ vertices? I am not sure if this is a possible 
registration issue to
mni305. 

Thanks in advance,
Taha
