The option you looked at:
> matlabbatch{1}.spm.util.voi.roi{1}.spm.mask
is a special case of the solution I presented in my previous email: if
your mask image was obtained by thresholding an SPM{.} with an
uncorrected threshold then the two approaches are equivalent.
You have the option to specify a threshold when using a mask for the
situation where the image you want to use hasn't been binarised yet.
Best wishes,
Guillaume.
