No. You could it in matlab by setting all of the left (or right)  segments to 0, eg,

a = MRIread('aseg.mgz');

ind = find(a.vol == 17); % Left hippo

a.vol(ind) = 0; % Set all left hippo to 0

and so on for the other segments

Dear Experts,

I'd appreciate your help with this question.

Are there any files which contain the left and right hemisphere segmentation of aseg.mgz separately? 

Thanks in advance.

Regards,

Fereshte
