if you have defects that large you should look at the inflated.nofix surface to see what they are.

What is your voxel resolution?

Thanks Bruce for your reply. I did run it thru' recon-all. It went for more than 2
days and then exited with XL defect error (convex hull was more than 14000 and vertex
size about 54000). So today I started by running the recon-all in parts. I did not
find anything wrong with brainmask files after running autorecon1. I am presently
running the autorecon-2 process. Will get back with the surf files when this process
is over.
Thank you again for your reply and support.

Kind regards, 

Sampada
