Dear Dr Wallius,
>Is it so that inclusive masking eliminates the voxels from current

Yes. To survive, a voxel must survive the thresholding of both contrasts,
as Karl mentioned in response to your previous query.

>height threshold?
Yes. To survive, a voxel must be above threshold in the test contrast, but
below threshold in the masking contrast, again as Karl pointed out
previously.

You're welcome.
Best wishes,
Richard Perry.
