Lingyan,

To convince yourself, add two or more separate lines like the following in 3dDeconvolve:

-gltsym 'SYM: +a1 -a2 \ +a2 -a3 \ +a3 -a4 \ +a4 -a5 \ +a5 -a6 \ +a6 -a7 \ +a7 -a8 \ +a8 -a9'
-gltsym 'SYM: +a1 -a2 \ +a1 -a3 \ +a1 -a4 \ +a1 -a5 \ +a1 -a6 \ +a1 -a7 \ +a1 -a8 \ +a1 -a9'
...

and check if you get the same F-stat value.
