In SPM2, the thresholding of the preprocessed data is set to 0.80 times
the grand mean: in spm_fmri_spm_ui, there's this code:
%-Masking structure automatically set to 80% of mean
%=======================================================================
try
TH = g.*gSF*defaults.mask.thresh;
catch
TH = g.*gSF*0.8;
end
I can't find anything similar in SPM99. Am I overlooking a piece of code
somewhere, or is this a true difference between SPM99 and SPM2?
