Thank you!!

BTW, is there any way to blur a mask made by using the TT Daemon? Some of the masks that I made with it are very small and cutting off areas that are still part of the ROIs of the brain. I used the following commands (samples down below).

3dcalc -a TT_Daemon::Brodmann_area_4 -expr 'step(a)' -prefix ba4
3dcalc -a ba4+tlrc. -expr 'step(a*x)' -dicom -prefix ba4_left
3dcalc -a ba4+tlrc. -expr 'step(a)*not(step(x))' -dicom -prefix ba4_right
3dcalc -a TT_Daemon::Brodmann_area_6 -expr 'step(a)' -prefix ba6
3dcalc -a ba6+tlrc. -expr 'step(a*x)' -dicom -prefix ba6_left
3dcalc -a ba6+tlrc. -expr 'step(a)*not(step(x))' -dicom -prefix ba6_right

3dcalc -a ba4_left+tlrc -b ba6_left -expr 'step(a)+2*step(b) -prefix LeftMultiRegion_mask1

3dfractionize -template GroupMCI_mask_group+tlrc -input LeftMultiRegion_mask1+tlrc -prefix LeftMultiRegion_mask1_fr -vote -clip 0.2+tlrc
