å-mrange 1 4: in this example, our mask dataset ROI_fred+tlrc has four ROIs draw within
it. This option tells the program
to take those 4 ROIs and compute an
overall average (collapsed across ROIs) for each voxel that falls within
the ROIs
í The exact numbers to average is
determined by the sub-bricks (#2, #5, #7) specified in our
functional dataset, fred+tlrc
åAdd the -q option to the above command line to suppress the voxel count printout (in this
example, -q suppresses Ò[137 voxels]Ó from appearing in the
shell
íE.g., 
44.287
44.28727.021-33.22íThis way you can
copy and paste the single column of averages to a 1D (i.e., text) file for later use in AFNI
åInstead of having
the results of 3dmaskave spewed into the shell, you can redirect ( > )the results into a text file and save them for later
use:
3dmaskave -mask ROI_fred+tlrc
-mrange 1 4 -q `func_fred+tlrc[2,5,7]`
