Hello Rahul, Thank you for your reply. I tried to combine the different regions to create one label for each lobe but could not figure it out. Can you suggest how I can combine different regions using tksurfer? Is there a wiki page where the steps are explained?

Hi Dhruman,
If you are interested in lobe-wise comparisons, you can indeed add up the individual regions of a specific lobe, create one massive label for that
lobe, and get statistics on those. For example, if you were interested in the temporal lobe, you could combine:
lateral occipital cuneus lingual pericalcarine
and generate an *h.occiptal.label (you can use tksurfer to combine the regions). You could do the same for the other labels and thus create a 'lobe based' parcellation. Once you are done, you can use mris_anatomical_stats to generate stats on the new labels you have generated.
best,
Rahul

Hi all,
I am interested in lobe wise surface measurement. I read Desikan et
al.
paper to understand that their atlas divides the lobes into different region and freesurfer uses that atlas to gets measurement for each region. Is it possible to load the Desikan label and edit it to fuse
all
the region belonging to each lobe and create a new label, which I
could
use to get surface measurement? Thanks in advance.
