Hello,
There is currently a difference between the criterion for masking between fslmaths and fslstats ( fslstats binarising at >0.5, fslmaths binarising at >0 ),
Hope this helps with what you are seeing,
Many Regards
Matthew

I was previously under the impression that this option would use any non-zero voxels in the masking image to mask the input image, similar to the -mas function in fslmaths. However, it appears as though it only uses voxels greater than 0.5 or so in the masking image.
