Hi,
It is likely to be the masking that is the difference.
Try fslstats -M instead of fslstats -m
All the best,

Dear FSL experts,
As for grand mean scaling, I find that there is a difference between using fslmaths -ing option and manual computation. For example: (1) fslmaths func -ing 10000 func_norm
(2) Mean=$(fslstats func -m); fslmaths func -mul 10000 -div $Mean func_norm
The above two methods would get unequal results and the latter one could scale grand mean to 10000. I wonder how the -ing option is implemented and why?
Best,
Yang Hu
