3B: Create a voxel-by-voxel mean for each timeseries
dataset with 3dTstat
GFor each voxel, add the intensity values of the 136 time
points and divide by 136
GThe resulting mean will be inserted into the ÒBÓ slot of
our percent signal change equation (A/B*100%)
foreach
run (1 2 3 4 5 6 7 8 9 10)
3dTstat
-prefix mean_r{$run} \
ED_r{$run}_vr_bl+orig
end
åUnless otherwise specified, the default statistic for 3dTstat is to compute a
voxel-by-voxel mean
íOther statistics run by 3dTstat
include a voxel-by-voxel standard deviation,
slope, median, etcÉ
