Hello,
I've been attempting to use the pre-threshold masking for an individual
level analysis but I'm having a bit of trouble. I transformed my mask into
the functional space before using it but I'm not seeing any difference in
activation within the masked region. It's properly masking any activation
outside of the ROI, but shouldn't I be seeing more activation (even just a
couple of voxels) due to the reduced number of multiple comparisons?
I've seen questions in the archive talking about the z-scores not changing,
but I couldn't find anything addressing whether the number of voxels within
the region should be changing. I've tried using a smaller mask too and that
didn't change anything either. Am I doing something wrong?
