In Reply to: how to get the average time course in ROI posted by jian on April 05, 2001 at 15:47:02:
ROIs were added after the main AFNI manual was written.
To get the average you want, you need to use the 3dmaskave
program; for example
3dmaskave -mask mmm+orig -q epi+orig > epimmm.1D
will average all the voxels in the mask mmm+orig from each
sub-brick of epi+orig, and write the results (one number per
line) to the standard output, here re-directed to the file epimmm.1D.
