Dear FSL expert: 
Firstly, I would like to thank for the reply from Douglas. Thank you for your suggestion! aparcstats2table is working!. 

Then, I have another question about the brainstem substructures. 
According to the guideline, https://surfer.nmr.mgh.harvard.edu/fswiki/MatlabRuntime
I download the environment and successfully installed. However, when I running command 
" recon-all -s subject -brainstem-structures"

it shows wrong message 

"ERROR: Flag -brainstem-structures unrecognized.
-s 201 -brainstem-structures" 

So how can I fix it? Is that due to FSL version problem? If yes, how can I update to freesurfer 6.0?


thanks!
Lawrence
