Hello SPMers-- 

I've created a mask image where all the significant voxels were assigned with '1' and others with '0'. 
However, after the mask image was created, I found those significant voxels were assigned with 0.9831, not 1. 
I don't know where the particular value came from and I'd like those voxels within the mask to be '1' to avoid any further confusion. 
Is there any way of doing it? Any help would be appreciated. 

Glen
