Automask Problem

Dear Dr. Yan,

I've encounted a prolem with automask generation. I know that I can skip Automask. But I am still very curious about its causes.

(1) My generated automask is like the attachment file 2 named 'automaskAfterFillCompletely.png (6.12 KB)'. For most slices, no-brain area was also included.

(2) In debug mode, I found that the mask before running   [mask , kk]=w_mask_fillin_completely(mask , nmm) (in line 106 of function [mask Header_Out] = w_Automask(Data, OutputFile, Verb)) seemed normal, which is uploaded as attachment file 1, ' automaskBeforeFillCompletely.png (17.06 KB)'.

(3) Is it possible that the function w_mask_fillin_completely() overdo the filling in?

Any piece of advices would be very much appreciated. Thanks.

Merry Xmas,

Dongcui Wang.
