By the way, I just ran 3dROIstats with a mask with 0-3 values but just got one average value (Mean_1). According to the explanation of 3dROIstats, I am supposed to have 3 different means (Mean_1, Mean_2, Mean_3) because I have 3 mask values. Am I right?
But I got only Mean_1. uh... this is so confusing. Would you please someone explain why this happens? I ran the command like this:
3dROIstats –nzmean –mask tstat2_mask+tlrc sub+tlrc >> avg.txt
