External Email - Use Caution Hello FreeSurfer Developers,
While I am using [vec,labels,cnames] = read_annotation('lh.aparc.annot'), I am getting values in labels which are not found in cnames.table(:,5). These values are 0. I assigned the values to the unknown area. However, when I looked at the number of vertices per brain regions I found that corpuscallosum has no vertices in the DK atlas. This is my first week using a neuroimaging software and Freesurfer is my first software to work on, so I just don't know if that's ok or if there is something wrong. I am attaching the output of a python code I wrote to count the number of vertices per brain region in the left hemisphere of a structural MRI image from our dataset. Thanks in advance, Mohamed T. Ali Ph.D. student, Bioengineering, University of Louisville.
